• Refereed, Archives of Environmental Contamination and Toxicology, Springer New York LLC, Children’s Hair Mercury Concentrations and Seafood Consumption in Five Regions of Japan, Emiko Kusanagi; Hitoshi Takamura; Shing-Jen Chen; Mayumi Adachi; Nobuko Hoshi, Exposure to methylmercury (MeHg) during the foetal and postnatal periods is known to have adverse effects on children’s development. However, little attention has been paid to MeHg exposure during early childhood in Japan. To examine the regional differences in MeHg exposure and seafood consumption and the association between MeHg exposure and seafood consumption and dental metal restorations, we measured the total mercury (T-Hg) concentration in hair as an MeHg exposure index, and using questionnaires, we measured the frequency and amount of seafood consumption and the presence of dental metal restorations in 118 children aged 3–6 years in five regions of Japan. The arithmetic and geometric means of the T-Hg concentrations in hair were 1.03 and 0.87 ppm, respectively, and approximately 40% of the children exceeded the United States Environmental Protection Agency recommendation of 1.0 ppm. Significant regional differences in the hair T-Hg concentrations were found among the five regions, and the regional differences were consistent with the traditional regional patterns of eating fatty fish. According to the regression analysis, the consumption of fatty fish, particularly tuna/swordfish, had a significant effect on hair T-Hg concentrations, whereas age, sex, the materials used for dental metal restorations, and other types of seafood or fish/shellfish had no significant effects., 01 Feb. 2018, 74, 2, 259, 272, Scientific journal, 10.1007/s00244-017-0502-x

Sericin supplementation resulted in decreased specific volume and darker crust color of the bread. No significant difference was observed in other physical properties. Sensory evaluation revealed that bread with up to 2 g of added sericin tended to be preferred. In a comprehensive evaluation of specific volume, crust color and preference rating by sensory evaluation, the optimal amount of added sericin was determined to be 2 g. Further, approximately 330 mg of sericin can be consumed in 1 slice of bread. We thus propose sericin-added bread as a desirable processed food that enables the effective ingestion of sericin., 2014, 20, 5, 1021, 1026, Scientific journal, 10.3136/fstr.20.1021

Oleifera Group)は奈良県在来のツケナである。コマツナのように草丈25cm前後で収穫され，収穫盛期は秋冬期である。在来種は収穫後に外葉が黄化しやすいという欠点を有し，このことが周年栽培，特に高温期の生産出荷を阻んできた。一方，大和マナは他のアブラナ科植物と同様にグルコシノレートを含有する。大和マナに含まれるグルコシノレートは，マウスを用いた実験で脂肪吸収を抑制することが見出され，抗肥満作用を有することが期待される機能性成分である。そこで，奈良県，ナント種苗，奈良先端科学技術大学院大学および奈良女子大学が協力し，収穫後の外葉の黄化が少なく，グルコシノレートを安定して含有するF1品種の'夏なら莱'と'冬なら菜'を育成した。その結果，大和高原南部地域と五條市を中心に周年栽培が急速に普及し始め，奈良県内に工場を有する大手薬品製造会社が大和マナの乾燥粉末を青汁の原料に利用するようになった。乾燥粉末の製造には，他の乾燥法と比較して運転費用が安価なドラムドライ法が利用されているが，本法で大和マナを処理すると，前処理の粉砕によって細胞内のミロシナーゼが作用し，機能性成分であるグルコシノレートの多くが揮発成分であるイソチオシアネートに分解され失われる。そこで，ドラムドライ法による乾燥に供する前のミロシナーゼを失活させる加熱方法として，製造現場で実践容易な蒸し加熱処理とゆで加熱処理を検討した。, Mar. 2013, 44, 44, 33-36, 36

The antioxidant activity, 1, 1-diphenyl-2-picrylhydrazyl (DPPH) radical-scavenging activity and oxygen radical absorbance capacity (ORAC) of the samples were also measured. The water and ash contents were not significantly different between Yamatoyasai and common vegetables, while the ascorbic acid content of some Yamatoyasai samples was lower than that of common vegetables. The total phenol contents of the Sensujimizuna and Hanamyouga samples were respectively 1.8 and 1.5 times higher than those of Mizuna and Myouga. In respect of the antioxidant activity, the DPPH radical-scavenging activity of Sensujimizuna and Hanamyouga was also higher than that of common vegetables. A 1.5-2 times higher ORAC value was found in Udakingobou, Hanamyouga, Kaorigobou, Yamatokikuna, and Sensujimizuna than that in common vegetables. It is clear from the results of this study that a substantial number of Yamatoyasai show higher antioxidant activity than common vegetables., Jun. 2012, 45, 3, 197-203, 203

Influent water samples, primary sedimentation tank water samples, and final effluent water samples were collected from sewage treatment facilities in Nagoya, Japan and their NIR spectra obtained. Partial least squares (PLS) models for total phosphate (TP), total nitrogen (TN), biochemical oxygen demand (BOD), total organic carbon (TOC), and turbidity of sewage water were constructed from the NIR data. The models provided good correlation between measurements obtained conventionally and those predicted from spectroscopy. Spectral variation induced by background interference in samples affected accuracy. Loading plots and score plots derived from PLS regression analysis resolved the background interference and allowed highly accurate predictions. Spectral variation induced by contamination in the sewage was a main predictor of sewage quality. These results show that NIR spectroscopy shows potential for in-line, non-destructive measurement of sewage quality., 2010, 61, 8, 1957, 1963, Scientific journal, 10.2166/wst.2010.070

• Refereed, FOOD CHEMISTRY, ELSEVIER SCI LTD, Effect of cooking on the antioxidant properties of coloured peppers, Ai Mey Chuah; Ya-Chi Lee; Tomoko Yamaguchi; Hitoshi Takamura; Li-Jun Yin; Teruyoshi Matoba, Pepper (Capsicum annum L.) has long been recognized as an excellent source of antioxidants, being rich in ascorbic acid and other phytochemicals. This study was conducted to investigate the effect of different cooking methods on the antioxidant properties of coloured peppers. Six varieties of peppers were subjected to different cooking methods, such as microwave heating, stir-frying and boiling in water, for 5 min individually. The cooked and raw peppers were analyzed for radical-scavenging activity (RSA) and total polyphenol content (TP) using 1,1-diphenyl-2-picrylhydrazyl-high-pressure liquid chromatography (DPPH)-HPLC and Folin-Ciocalteu methods, respectively. The samples were also evaluated for ascorbic acid content (AsA) by HPLC. Total carotenoid content was determined spectrophotometrically. Results suggest that there is no significant (P > 0.05) difference in RSA, TP, AsA and total carotenoid contents between the cooked and raw peppers when processed for 5 min. However, the cooked peppers show marked differences (P < 0.05) in the RSA, TP and AsA when cooked for 5 min in boiling water with further reduction observed after boiling for 30 min. This may be due to the leaching of antioxidant compounds from the pepper into the cooking water during the prolonged exposure to water and heat. Therefore, it is vital to use less water and cooking time and also to consume the water used for boiling so as to obtain the optimum benefits of bioactive compounds present in peppers. It is concluded that microwave heating and stir-frying without using water are more suitable cooking methods for pepper, to ensure the maximum retention of antioxidant molecules.

Hirohara; A. Bhadra; T. Ishida; H. Matsuda; H. Takamura; T. Matoba, Generally the main component of fishy flavor is considered to be trimethylamine. On the other hand, carbonyl compounds, produced from oxidation of polyunsaturated fatty acid by lipoxygenase or by autoxidation, might have some contribution to the fishy flavor. Since sardine skin contains high levels of polyunsaturated fatty acids and lipoxygenase, carbonyl compounds may be generated more easily than trimethylamine. In this study, volatile flavor compounds of sardine were analyzed by gas chromatograph-mass spectrometry and gas chromatograph olfactometry combined with solid phase microextraction. Then, the flavor components that contribute to fishy flavor were identified. At normal pH (6.2), trimethylamine was not detected or sensed from the fresh sardines. When the pH was raised, the amount of trimethylamine became higher. Trimethylamine flavor was weak at pH 9 and strongly sensed at pH 11 or higher. On the other hand, 33 other compounds were positively or tentatively identified, including 8 hydrocarbons, 5 ketones, 1 furan, 1 sulphur compound, 12 aldehydes, and 6 alcohols in fresh sardines. Among them, 2,3-pentanedione, hexanal, and 1 penten-3-ol were the main components. Forty-seven flavors were detected by gas chromatograph-olfactometry. Among them, paint-like (1-penten-3-one), caramel-like (2,3-pentanedione), green like (hexanal), shore like ((Z)-4-heptenal), citrus note (octanal), mushroom like (1-octen-3-one), potato-like (methional), insect-like ((E,Z)-2,6-nonadienal), and bloody note (not identified)were strongly sensed. From the aforementioned results, it can be concluded that these compounds rather than trimethylamine contributed to fresh sardine flavor., Jan. 2008, 73, 1, S83, S88, Scientific journal, 10.1111/j.1750-3841.2007.00608.x

Most of the spices showed high 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical-scavenging activity (4-1353 mu mol Trolox eq./g), peroxy radical-scavenging activity (31-1019 mu mol Trolox eq./g), and total phenol content (5-1267 mu mol gallic acid eq./g). Clove was found to have the highest radical-scavenging activity followed by allspice and cinnamon. After heating, both DPPH and peroxy radical-scavenging activities as well as the total phenol content increased in most of the spices. A distinct increase in the activities was found in some spices such as black pepper, red pepper and turmeric. A high correlation coefficient was found between the total phenol content and peroxy radical-scavenging activity., Aug. 2006, 12, 3, 178, 185, Scientific journal

• Refereed, FOOD SCIENCE AND TECHNOLOGY RESEARCH, KARGER, Stabilizing effect of grape seed extract on ascorbic acid, Satoshi Kitao; Madoka Teramoto; Tomoko Yamaguchi; Hitoshi Takamura; Teruyoshi Matoba, L-Ascorbic acid (AsA) has numerous biological activities. It is known that AsA is unstable under neutral and alkaline conditions, degrading almost completely within several hours, whereas it is relatively stable under acidic conditions. The present study investigated the effect of grape seed extract (GSE), which contains proanthocyanidins, on the stability of AsA under neutral and alkaline conditions. The addition of GSE to AsA solution in 3,3'-dimethylglutaric acid-tris(hydroxymethyl)aminomethane-2-amino-2-methyl1,3-propanediol (GTA) (50 mM, pH 7.0 or 10.0) buffer significantly increased the remaining amount of AsA and the 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical-scavenging activity, compared with those of AsA alone. In particular, it was clarified that GSE contributed to the stability of AsA at an alkaline pH. We also investigated the effect of GSE on the stability of AsA under quasi-physiological conditions. It was revealed that GSE stabilized AsA in simulated intestinal juice (pH 8.5) at 37 degrees C. DPPH radical-scavenging activity was closely correlated with the remaining amounts of AsA. The present results, although not directly transferable to in vivo conditions, suggest that GSE may stabilize AsA under neutral and alkaline conditions and affect the physiological activity of AsA., Feb. 2006, 12, 1, 15, 21, Scientific journal

In this work, the changes of radical-scavenging activity in shredded red and green cabbage leaves during storage were determined as well as ascorbic acid and polyphenol contents. Shredded cabbage leaves were stored at 10degreesC for 7 days in the presence or absence of oxygen. Radical-scavenging activity, ascorbic acid content, and polyphenol content of shredded cabbage leaves remained for 7 days in the presence and absence of oxygen. These results demonstrate that the radical-scavenging activity, ascorbic acid, and polyphenols are stable in shredded cabbage leaves and that oxygen does not affect the activity and active components., 2004, 21, 1-4, 297, 299, Scientific journal

The contribution of ascorbic acid to this activity was also determined. All dried fruits contained DPPH radical-scavenging activity with hawthorn, apricot and blueberry having the highest. Other dried fruits containing rind also had high activity.

Even though they rapidly decomposed at 180 degreesC, some decomposition products still had radical-scavenging activity. When rutin was heated in the presence of chlorogenic acid, decomposition of rutin was almost totally inhibited at 100 degreesC, but was reduced at 180 degreesC. These results suggest that the radical-scavenging activity is more stable than the content of original polyphenolic compounds in foods during cooking and processing., Jan. 2004, 69, 1, C7, C10, Scientific journal

The activity and active compounds in home-made wet-ripened (jukushi), commercial dry-ripened (hoshigaki), and commercial alcohol-treated (sawashigaki) persimmon samples were also examined. The activity of astringent persimmon during dry-ripening decreased with a reduction in the astringent taste. resulting in that the activity after 5 weeks of dry-ripening being about 1% of that, of the original persimmon. The amounts of ascorbic acid and polyphenols after 5 weeks of dry-ripening respectively decreased to 0 and 5% of those in the original persimmon. The activity of the commercial dry-ripened and alcohol-treated persimmon was similar to that of the home-made dry-ripened persimmon prepared in this study. However, the activity of wet-ripened persimmon having no astringent taste was comparable to that of fresh astringent persimmon., Jun. 2003, 54, 6, 449-456, 456

In the case of burdock and lettuce, which have a high activity of polyphenol oxidase, the radical-scavenging activity and the content of total phenol and chlorogenic acid decreased drastically within 1 min. In the case of broccoli, however, only a small decrease of radical-scavenging activity was observed, and total phenol and chlorogenic acid decreased almost not at all. The decrease of the activity in broccoli depended on the oxidation of ascorbic acid by ascorbate oxidase.

We also determined color, acid value, anisidine value, polymerized compounds, and polar compounds. The viscosity-increasing ratio was highly correlated with the amount of polymerized compounds (correlation coefficient: 0.980). The traveling distance in PCtester was also highly correlated with the amount of polar compounds (correlation coefficient: 0.921). However, the acid value and the anisidine value were less correlated with the amount of polymerized or polar compounds. Polymerized compounds and polar compounds were determined usually by HPLC, which needs long time. However, the determination of viscosity-increasing ratio and the PCtester method are simple and rapid. Therefore, these methods in combination with acid value determination can be used as an easy comprehensive frying oil control method for business use. We recommend the viscosity-increasing ratio 15-20% and the PCtester traveling distance 24-27mm as the criteria for wasting deteriorated frying oil., Jun. 2002, 49, 6, 422-427, 427, 10.3136/nskkk.49.422

The deoxyguanosine oxidation method could not determine the activity since food polyphenols were pro-oxidative in this assay.

Although radical-scavenging activity was found in the early stages of the Maillard reaction, the scavenging activity appeared before the formation of the pigments.

The content of ascorbic acid having radical-scavenging activity was highest in burdock among the 18 fresh vegetables tested. In some vegetables, the activity increased in spite of the loss of ascorbic acid content after boiling, while in other vegetables, the activity had decreased after boiling. This decrease may be due to release of the activity from cooked tissue into the cooking water during boiling. Both activity and ascorbic acid content of the vegetables cooked in a microwave were generally higher than in those cooked by boiling., 2001, 7, 3, 250, 257, Scientific journal, 10.3136/fstr.7.250

The beverages were preserved at 5℃, 25℃, and 35℃ in the air or in a vacuum. The decrease in radical-scavenging activity and ascorbic acid content was found to be greater with increasing preservation temperature, this being more apparent in the air than in a vacuum. Long-term preservation, however, resulted in the radical-scavenging activity and ascorbic acid content decreasing even at a low temperature in a vacuum. Those beverages with a higher content of sugar retained a high level of ascorbic acid, which may have been due to the protective effect of sugar against ascorbic acid oxidation., Feb. 2001, 34, 1, 68-72, 72

In this study, we examined effects of various beverages and seasonings on the stability of HPOD. Teas, carrot juice, tomato juice, and 5% soy sauce showed the suppressive effect on the decomposition of HPOD. This may be due to the radical scavenging activity of tea polyphenols, carotenoids, and amino-carbonyl reaction products. However, 50% soy sauce showed the accelerative effect on the decomposition of HPOD because of iron ions., Dec. 2000, 51, 12, 1137-1143, 1143

Matoba, The storage stability of a Bangladeshi traditional semi-fermented fish product, chapa shutki, was evaluated. The product was stored for 3 months at 20°C and 35°C under 40% and 80% relative humidity, which were apparently similar atmospheric conditions to those of the winter and summer in Bangladesh, respectively. The fatty acid composition did not change markedly during storage. The initial carbonyl value (COV) and thiobarbituric acid reactive substances (TBARS) value of the sample were 28.4 meq/kg and 36.1 mg malondialdehyde (MDA)/kg of oil, respectively. These values only slightly changed during 3 months of storage regardless of the storage conditions. The COV and TBARS values were in the range of 19.8-22.0 meq/kg and 31.4-36.4 mg MDA/kg of oil, respectively. These results indicate that the lipids of chapa shutki were essentially not susceptible to oxidative deterioration. No mutagenic activity was detected ever in a very concentrated solution of chapa shutki. The initial radiacal-scavenging activity of chapa shutki was 373.8 mg Trolox eq/100 g of fish on a dry weight basis. The activity gradually decreased throughout the storage period. Storage conditions had no effect on the decrease of the radical-scavenging activity. (Received January 28, 1999 ; Accepted in revised form June 19, 2000), Aug. 2000, 51, 8, 683-690, 690

Matoba, It is important to know the behavior of lipid peroxidation products in foods because lipid hydroperoxide are known to decrease food quality and safety. We have reported that the stability of linoleic acid hydroperoxide (hydroperoxyoctadecadienoic acid ; HPOD) in the water system. Although the hydroperoxides have been believed to be so unstable at high temperature that they decomposed immediately, the stability of HPOD at high temperature has not been exactly provided. In this study, we examined HPOD decomposition in the oil system kinetically. In tri-n-caprine as the model of oil system, HPOD was lost completely within I h at 170℃, while only 20% was lost for 2 h at 100℃. Moreover, 40% remained after 72 h at 50℃. Then, HPOD was stabler in oil than in water. According to activation energy, however, it was estimated that HPOD decomposition mechanism in oil was similar to that in water. Thus the homolytic cleavage of the hydroperoxy group to alkoxy and hydroxyl radicals was responsible for the decomposition of HPOD in both systems. Besides, butylated hydroxytoluene is such a strong radical scavenger that it could suppress the decomposition of HPOD., Aug. 2000, 33, 3, 377-380, 380

This result suggests that daily eating of commercially prepared box lunches cannot satisfy the required intake of calcium, iron, potassium, manganese, and zinc. In addition, the commercially prepared box lunches and daily dishes contained more sodium than the home-prepared equivalents.

We used various starches and powder foods as the model. NIR spectra of various solvents containing water showed a clear band due to water around 1930 nm, Of the solvents used, this band in N,N-dimethylacetamide (DMA), N,N-dimethylformamide (DMF) and dimethyl sulfoxide (DMSO) systems was not shifted by the change of the moisture content. Then, the moisture was extracted from starch by these solvents. Approximately 60% was consistently recovered in a single-step extraction by DMA or DMF. The extraction by DMSO was too viscous to handle. The calibration equation was developed from the results for the extraction from starch by DMA, Then, moisture contents of powder foods were predicted using the calibration equation. For six of eight foods, good correlations were obtained between the laboratory values and the predicted values. These results suggest that this NIR method coupled with extraction is useful for the determination of moisture content with a common calibration equation for various kinds of foods., 1998, 6, 1-4, 235, 240, International conference proceedings

The activity was evaluated by measuring the decrease of DPPH detected at 517 nm. By using this novel method, we determined the free radical-scavenging activity of several antioxidants: ascorbic acid, alpha-tocopherol, Trolox, and cysteine. The results gave good correlation between the radical-scavenging activity determined by HPLC and by conventional colorimetry. This methodology was applied to determine the free radical-scavenging activity of 8 beverages. The activity of coffee was the highest, followed by red wine, green tea, oolong tea, black tea, rose wine, white wine, and orange juice. The results well agree with those of previous reports. This method is expected to be useful for a simple and rapid determination of free radical-scavenging activity in colored foods, because coloring substances in foods do not interfere with the measurement., Jun. 1998, 62, 6, 1201, 1204, Scientific journal

The fish sauce was rich in both taste derived from fish and flavor like soy sauce. In this study, browning reaction during processing of the fish meal-fish sauce was determined. Five kinds of the fish sauces were prepared from sardine meal by 6-month fermentation with different kinds of koji. Soy sauce was also prepared for control. Color intensity of the fish sauces increased during fermentation, but was much lower than that of soy sauce. It was reported that browning of soy sauce is derived mainly from amino-carbonyl reaction between amino compounds and reducing sugar. However, reducing sugar amount varied among five fish sauces and was not related with color intensity. Amino acid and amino compound levels in the fish sauces were lower than those in soy sauce. Polyphenol oxidase activity and polyphenol compound level were also lower in the fish sauces than in soy sauce. In addition, iron content in the fish sauces was lower than that in soy sauce. These results demondstrate that color intensity of the fish meal-fish sauce was lower than that of soy sauce due to lower levels of amino acids, amino compounds, polyphenol oxidase activity, polyphenol compounds, and iron., May 1998, 31, 2, 96-102, 102

(3Z)-alkenals have a fleeting existence. In this study it was shown that soybean seeds possess two pathways that metabolize (3Z)-alkenals. One is a soluble (3Z):(2E)-enal isomerase that transformed (3Z)-hexenal and (3Z)-nonenal into the corresponding (2E)-alkenals. The other was a membrane-bound system that converted (3Z)-hexenal and (3Z)-nonenal into (2E)-4-hydroxy-2-hexenal and (2E)-4-hydroxy-2-nonenal, respectively. The latter conversion was shown to absorb O-2 with a pH optimum of 9.5. Little effect observed with lipoxygenase inhibitors suggested that oxidation was not catalyzed by lipoxygenase. Instead, a specific (3Z)-alkenal oxygenase was implicated in forming intermediate alkenal hydroperoxides. Hydroperoxide-dependent peroxygenase (epoxygenase) is known to reduce hydroperoxides to their corresponding hydroxides and is also known to be inhibited by hydrogen peroxide preincubation. Consequently, intermediate 4-hydroperoxy-2-alkenals could be observed after inhibiting hydroperoxide-dependent peroxygenase by preincubation with hydrogen peroxide. Because 4-hydroxy-2-alkenals are potent toxins, these compounds may be produced as nonvolatile plant defensive substances., Sep. 1996, 1303, 2, 83, 91, Scientific journal

The samples were examined in the intensities of color, saltiness, sweetness and umami. As a whole, the results varied widely, indicating that the local character of the taste has been losing due to the development of commerce and traffic. The other factors except localization would effect on the preference of the taste. But samples in Kansai area, especially Osaka, exhibited lower level of the intensities of color, saltiness and sweetness than those in other cities. This suggests that Kansai area, especially Osaka, has the characteristic preference of the taste., Jan. 1996, 47, 1, 59-64, 64

Isomeric pentene dimers were also produced and were presumably derived from the combination of two pentene radicals. 13(S)-Hydroperoxy-9(Z),11(E)-octadecadienoic acid (13S-HPOD) was, by contrast, a poor substrate. Activity with 13S-HPOT increased 24-fold under anaerobic conditions reminiscent of a similar anaerobic promoted reaction of 13S-HPOD catalyzed by lipoxygenase (LOX) in the presence of linoleic acid. However, prior to ion-exchange chromatography, cleavage activity did not require linoleic acid. After separation by gel filtration followed by ion-exchange chromatography, cleavage activity was lost but reappeared in the presence of either linoleic acid or dithiothreitol. Under these conditions cleavage activity was coincident with the activity of types 1 and 2 LOX. LOX inhibitors suppressed the cleavage reaction in a manner similar to inhibition of LOX activity. Heat-generated alkoxyl radicals derived from either 13S-HPOT or 13S-HPOD afforded similar products and yields of 13-oxo-9(Z),11 (E)-tridecadienoic acid compared to the enzymic reaction. The product 1-penten-3-ol may be the precursor of the ''raw-bean'' volatile ethylvinylketone., Jul. 1995, 108, 3, 1211, 1218, Scientific journal

However, the relationship between the molecular structure and emulsification properties of edible oils is not understood. To analyze this relationship, the emulsification susceptibilities of various kinds of single triacylglycerol molecular species and edible oils were systematically measured. The emulsification susceptibility increased as the carbon number and double bond number of triacylglycerol molecular species consisting oils increased. In addition, the effect of the double bond number was predominant. These results demonstrate that the emulsification property is affected by the molecular structure of oils. Furthermore, the emulsification susceptibilities of edible oils modified by enzymatic interesterification were changed as compared with those of native oils. This shows that emulsification property can be changed by the modification of the molecular structure of edible oils., Jul. 1994, 58, 7, 1258, 1261, Scientific journal

The intensities of the absorption due to peptide bonds were different depending on the kinds of proteins examined. The absorption of bovine serum albumin at 2170 nm decreased by reducing its disulfide (S-S) bonds. The absorption of poly-L-glutamic acid in the alpha-helix state at 2170 nm was stronger than that in the random coil state. These results suggest that the secondary structures of proteins affect the absorption at 2170 nm. The extent of contribution of the secondary structures to the absorption intensity was statistically predicted using 9 proteins which have different contents in secondary structures such as alpha-helix, beta-sheet and random coil structures. It was found that the relative extent of the alpha-helix, beta-sheet and random coil structures to the absorption at 2170 nm was approximately 2:1:1., 1994, 41, 1, 65, 69, Scientific journal

As the carbon number of the fatty acid moieties of triacylglycerol increased, the initial rates of oil absorption and dehydration decreased ; however, the maximal oil absorption and dehydration were similar. According to the oil drainage behavior, the oils were classified into two groups, i.e., solid fats and liquid oils. In the case of solid fats, the maximal oil drainage increased as the melting point dropped. On the other hand, the oil drainage rate for liquid oils increased with decreasing viscosity. These results demonstrate that the molecular structure of edible oils affects the deep fat frying properties., Dec. 1993, 44, 12, 1027-1032, 1032

The analysis is based on the reaction of 2,4-dinitrophenyl-hydrazine with aldehydes and the subsequent formation of the quinoidal ion under basic conditions. The aldehydes react with 2,4-dinitrophenylhydrazine in both ethanol and aqueous-ethanol media. The optimal wavelength to determine the total carbonyl compounds is 425 nm where the molar absorption coefficient of saturated aldehydes equals that of unsaturated aldehydes. The method can be used to determine all aldehydes in aqueous food media., Sep. 1993, 70, 9, 881, 884, Scientific journal

Molecular sizes of the polymers were not affected by a reducing agent, dithiothreitol. The blockage of amino groups by succinylation prevented the polymerization of lysozyme. The cleavage of disulfide bonds by carboxy-methylation of sulfhydryl groups changed the conformation of lysozyme and promoted the polymerization. These results indicated that not disulfide bonds but amino groups of lysine residues contribute to the polymerization of lysozyme. It was also suggested that the conformational change of lysozyme affects the polymerization., Feb. 1993, 44, 2, 103-108, 108

The accuracy of the corrected calibration was tested against separate data sets with each oil content.

This study elucidated the effects of grilling on total polyphenol content (TPC), antioxidant capacity, and the inner structures of eggplant. After identical hollowing, cylindrical eggplant samples were prepared and were then grilled until their center temperatures (CT) respectively reached 50, 65, 75, 85, and 95 degrees C. Chemical assays and observations of the inner structures clarified that TPC and 1, 1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity decreased as CT increased when CT was below 65 degrees C. Results also showed that TPC and DPPH radical scavenging activity increased as CT increased when CT was between 65 degrees C and 95 degrees C. For CT 65 degrees C, the samples retained polyphenol oxidase (PPO) activity up to 40% of the raw state activity. The 3 grilled eggplant models, chlorogenic acid, chlorogenic acidsugar and chlorogenic acidamino acid model, yielded results showing that phenol functional groups on chlorogenic acid were thermally stable and that phenol functional groups on chlorogenic acid reacted neither with sugar nor with amino acids. Results show that PPO activity is a primary reason for the decrease of the 2 indices. Optical microscopic and scanning electron microscopic observations revealed collapsed cells and inter-tissue cracks around the surface area for CT 85 and 95 degrees C. Scanning electron microscopic observations clarified that intercellular bonds for CT 85 and 95 degrees C became thinner than those for CT 75 degrees C around the middle area. The phenomena explained above are reasons for the increase of TPC and DPPH radical scavenging activity. Practical Application The findings of this research can support the development of healthier cooking practices that directly benefit consumers. The results of this research are expected to be illustrative to investigators of academic and commercial sectors who are interested in heat-induced changes that occur in eggplant during grilling. Moreover, the results reported herein can facilitate understanding of the heating effects and changes occurring in other cooked vegetables., Jan. 2017, 82, 1, 202, 207, Scientific journal, 10.1111/1750-3841.13567

   【結果】脱水率は、豚カツ、サツマイモともに「シャロウ1/2」で低かった。吸油率は、豚カツでは油量による差はみられなかった。中心温度は「シャロウ1/2」では温度上昇が遅かった。官能評価の評点法は、豚カツ、サツマイモともに外観、におい、揚がり具合、テクスチャーおよび総合において「シャロウ1/2」が有意に低い評価であった。順位法では、豚カツは、「ディープ」、「シャロウ1」、「シャロウ1/2」の順に好まれた。サツマイモの「シャロウ1/2」では仕上がりが不均一で水っぽく感じられ、脱水率の結果と一致していた。以上の結果から、油量の違いは揚がり具合に影響を及ぼすことが明らかになった。, 2012, 24, 0, 59, 59, 10.11402/ajscs.24.0.59.0

  【目的】これまで鶏肉が有するラジカル捕捉活性とその活性成分について検討してきた。最近、ハーブ中のポリフェノールが第三次機能成分として有効であることが報告され、鶏の飼料にハーブを給餌したハーブ鶏が飼育されている。そこで本研究では、鶏を肥育する飼料に注目し、通常肥育のブロイラー、ハーブ鶏、地鶏（南部鶏）のラジカル捕捉活性を比較することで、鶏肉への飼料の影響を検討した。
  【方法】鶏肉について、モモ肉、ムネ肉、ササミ、手羽元、皮、肝臓、砂肝の部位別に水溶性画分（水抽出）および脂溶性画分（クロロホルム・メタノール抽出）のラジカル捕捉活性および活性成分を測定した。ラジカル捕捉活性として、DPPHラジカル捕捉活性をDPPH-HPLC法で、酸素ラジカル捕捉活性をデオキシグアノシン酸化法で測定した。また、活性成分として、アスコルビン酸、トコフェロール、総ポリフェノール、グルタチオンを測定した。
  【結果】三種の鶏肉とも、全ての部位においてラジカル捕捉活性を示した。特に肝臓が高い活性を示した。いずれの部位においても水溶性画分の活性がほとんどを占めていた。ハーブ鶏や地鶏については、ムネ肉のラジカル捕捉活性が通常肥育のブロイラーと比較して有意に高かった。活性成分として、グルタチオンが少量含まれていたが、アスコルビン酸とトコフェロールはほとんど含まれなかった。また、DPPHラジカル捕捉活性および酸素ラジカル捕捉活性は、いずれも総ポリフェノール量との相関関係がみられた。ハーブ鶏では、モモ肉およびムネ肉においてポリフェノールがブロイラーよりも有意に多く、ハーブ給餌の影響が示唆された。地鶏についても、ムネ肉、肝臓においてポリフェノールがブロイラーよりも有意に多かった。, 2009, 21, 0, 1057, 1057, 10.11402/ajscs.21.0.1057.0

  【目的】これまで日本調理科学会近畿支部揚げる・炒める分科会では、家庭での揚げ調理に関して、多様化、健康志向、簡便化が進みつつあることを報告してきた¹⁾²⁾。しかし依然として揚げ物は多くの消費者に好まれており、健康志向や簡便化が揚げ物を作る・食べる等の個人の行動に及ぼす影響は明らかではない。そこで今回は、揚げ物の調理頻度及び食べる頻度と食生活に対する健康観との関連を明らかにすることを目的とした。
  【方法】調査時期：2007年5～6月、調査対象：近畿地区の大学に在学の自宅通学生の家庭（回答者は主調理担当者）、調査法：質問紙による自己記入式留置法、有効回答数506部（回収率61.5％）。
  【結果】揚げ物を作る頻度・食べる頻度により3群に分け、A群（作る頻度・食べる頻度とも週2～3回以上、n＝127）、B群（作る頻度週1回以下、食べる頻度週2～3回以上、n＝120）、C群（作る頻度・食べる頻度とも週1回以下、n＝259）とした。作る頻度・食べる頻度が高いほど揚げ物を好み、特に「好き」はA群で多く、好きだからよく作ることが窺えた。C群では食べない理由として「油っぽい」「高カロリー」等が多かったが、好きな理由として59％が「おいしい」を挙げており、C群は揚げ物が嫌いなのではなく、油を避けていると考えられた。B群では食べる理由として57％が「弁当・定食に入っている」を挙げており、A群に比べて受動的であった。一方、健康な食生活に重要と考えることは3群でほとんど差がなかったが、実行していることは「食物繊維を多くとる」等でA、C群が多く、「揚げ物を避ける」等でC群が多いといった差が見られた。以上より、A、C群はいずれも健康意識が強いが、揚げ物に対しては、C群は「避ける」、A群は「自分でコントロールして食べる」という違いが明らかになった。

The results were compared with those of our previous questionnaire conducted in 1998. The results show that those edible oils claimed to be good for health are well recognized to reflect the strong concern about life-style related diseases. As was the case in the previous investigation, each household regularly stores on average three kinds of edible oil such as rapeseed (canola), safflower and corn oils. The proportion of rapeseed oil was higher in the second survey, while that of safflower and corn oils was lower. More households now purchase edible oils based on their value to health than before. The number of households that cook fried dish has increased. In the case of deep-fried dish, however, the households were divided into those with a higher frying frequency and those with a lower frying frequency. These results indicate that health consciousness has become stronger in the purchase, use, cooking method and disposal of edible oils., 20 Aug. 2003, 36, 3, 274, 283, 10.11402/cookeryscience1995.36.3_274

After boiling of vegetables, the radical-scavenging activity increased in burdock, green pepper, asparagus, eggplant, and carrot, while the activity in other vegetables decreased. In most cases, however, the total activity of cooked vegetable and cooking water was higher than that of fresh vegetables. Microwave heating increased the radical-scavenging activity in 9 of 14 vegetables. These results suggest that the intake of vegetables with cooking water or microwave-cooked vegetables can be recommended to use radical-scavenging components efficiently. In the process of curry cooking, the radical-scavenging activity of spices decreased, while that of vegetables increased. The radical-scavenging activity of curry also decreased after heating., 2002, 816, 34, 43, Scientific journal

  The respondent used an average of three types of edible oil, the most popular combination being salad oil, sesame oil and olive oil. The oil most commonly used for deep frying was salad oil, with safflower and rapeseed oil also being used for this.
  The criteria applied for buying oil for deep frying were the price, variety and expiration date. The parameters used for determining the life of the frying oilswere, in the order of number of answers, color (light brown), number of times used, smell and foaming property. It was apparent that the criteria for purchase and the frequency of deep frying for home cooking affected the utilization of edible oils for deep frying.
  These results indicate a perception of health and convenience in the utilization of edible oils for deep frying in home cooking., 20 May 2000, 33, 2, 236, 243, 10.11402/cookeryscience1995.33.2_236

Soybean oil (500 g) was heated at 170°C using an electric fryer. Fifty gram of three types of foods, Spanish mackerel, chicken fillet and potato, were deep-fat fried every 15 minutes. Frying was continued until the flavor score of oil dropped below 3.
  The life spans of the frying oils defined as the frying time until the flavor score reached to 3 were shorter by fish and meat frying than potato frying. The life spans were not significantly different between Spanish mackerel and chicken, in spite of a marked difference in their polyunsaturated fatty acid contents.
  The flavor scores of the fried foods tended to be affected extensively by the flavor of frying materials and by personal preference. On the other hand, the flavor scores of frying oil decreased with the progress of frying independently of the frying materials. In the sensory test, the foods fried in the oils with a flavor score 5 or 4 showed good flavor. However, the flavor of the foods fried in the oils with a flavor score 3 began to deteriorate. These results suggest that the flavor score of frying oil is useful to determine the life span of frying oil., 1998, 31, 3, 214, 219, 10.11402/cookeryscience1995.31.3_214

  方法 まず、未乾燥のジュース残渣はパン生地の水分量に影響するため、乾燥方法を検討した。次に、グルテンフリー米粉パン製造に適した発酵時間・発酵温度の検討を行い、グルテンフリー米粉パンの製造方法を確立した。その後、ネーブルオレンジから得られたジュース残渣を乾燥して得られた粉末をグルテンフリー米粉パン製造の際に添加した。ジュース残渣を添加したパンを調製し、物性値（生地の膨化度、生地の粘度、焼成パンの比容積、焼成パン切断面の観察、テクスチャー解析）の測定、および官能評価を行い、ジュース残渣の最適添加量を検討した。
  結果 ジュース残渣の乾燥は電子レンジを用い、乾燥後、ミルで粉砕しふるいにかけることを繰り返すことで、ジュース残渣粉末を調製することができた。ジュース残渣粉末を添加した米粉パンは未添加の米粉パンと比べ、生地の膨化度、生地の粘度、焼成パンの比容積の測定において高い値を示し、官能評価において高い評価を得た。これらの結果から、ジュース残渣は、グルテンフリー米粉パンの製パン性を高めることが示唆された。, 2017, 29, 144, 144, 10.11402/ajscs.29.0_144

Effects of freezing on the formation of the structure and that of the presence of fibers on the texture were evaluated, showing the properties similar to animal meat one. Sensory evaluation also showed that the texture was significantly preferable to that of conventional soy-based meat analogue and was closer to animal meat. These results suggest that the proposed method would be promising for realizing soy-based meat substitutes with a texture closer to animal meat., 15 Mar. 2022, 23, 1, 35, 44, Scientific journal, False, False, 10.11301/jsfe.22606

  【方法】一年中入手が可能で、且つ脂質含量が高い魚の代表であるマサバに、抗酸化性を持つ香味野菜を加え、焼く、煮る調理操作を行い、調製した試料をホモジネートし、揮発性成分を固相微量抽出法で抽出した。それをGC、GC-MS、GC-Olfactometoryで分析し、揮発性成分の定量とスニッフィング分析を行った。機能性の測定では、ORAC法を用いて抗酸化活性を測定した。
  【結果】揮発性成分の定量において、香味野菜を加えて調理することにより脂質劣化に由来する揮発性成分が減少した。スニッフィング分析では、香味野菜を添加して調理した試料で、腐敗臭、魚臭が軽減する傾向がみられた。また機能性の測定では、香味野菜を加えることにより抗酸化活性が増加する傾向がみられた。これらの結果には、香味野菜由来の抗酸化成分が寄与していると考えられる。以上の結果から、香味野菜を加えて調理したサバは嗜好性及び機能性においてより優れていることが示唆された。, 2014, 26, 182, 182, 10.11402/ajscs.26.0_182

  【方法】試料はジャガイモ（長崎県産）を用いた。調味液として醤油（濃口）は0～20％溶液、みりん（本みりん）は0～40％溶液とし、ガスコンロおよび電子レンジを用い調理器具と蒸らし操作の有無を組み合わせた５種類の「煮る」「蒸らす」調理法について比較した。破断応力値はレオメーター（山電製）にて測定した。消費ガス量・電力量から、消費一次エネルギー量及びCO₂排出量を算出し、比較検討した。
  【結果】すべての調理法で破断応力がほぼ同様の試料を得ることができた。ガス調理では、消費一次エネルギー量、CO₂排出量ともに、醤油濃度およびみりん濃度の違いによる有意差はなかった。一方、電子レンジ調理では、みりんを使用した場合は濃度による違いは認められなかったが、醤油を使用した場合は、CO₂排出量のみ醤油濃度が高くなるにつれ有意に増加したことから、醤油に含まれる塩分の影響が示唆された。さらに、どの場合も蒸らし操作を組み合わせることにより消費一次エネルギー量およびCO₂排出量が削減されることが明らかとなり、エコロジー調理につながることが期待される。, 2014, 26, 76, 76, 10.11402/ajscs.26.0_76

The differences in composition and quantity of carbonyl compounds were measured to assess whether a sample oil could be identified by a sensory evaluation. Although it was possible to recognize the difference of carbonyl value in the initial stage of deterioration of the oil, this became more difficult as the deterioration advanced. The influence of such other factors as viscosity and polar compounds is thought to have been the reason for this., 2009, 42, 2, 117, 122, 10.11402/cookeryscience.42.117

We first examined the relationship between deterioration of frying oil and its flavor by using flavor scores 5, 4, 3, 2 and 1 (flavor score 5 was defined as fresh oil ; flavor score 1 as the most deteriorated oil). Flavor score 3 was defined as the frying oil's rancid point (heavy flavor reversion, slighty rancid and buttery). To determine the heating time for the oil to reach flavor score 3, potatoes were successively fried every 4 hours in soybean oil at 180℃ for 4 minutes. Anisidine and carbonyl values of the frying oil with flavor score 3 were also measured. This experiment was carried out 11 different laboratories, and the data varied : the shortest and longest times for the oil to reach flavor score 3 were 16 and 50 hours, respectively. To minimize this difference in time, soybean oils with different stages of thermal oxidation were prepared flavor scores 5 to 1 ; and all the researchers decided upon the standard flavor of those oils. After standarization, the second experiment was carried out in the same manner as that of the first experiment. The data were relatively consistent : the shortest and longest times for the oil to reach flavor score 3 were 16 and 22.5 hours, respectively, and the average time was 19.5 hours. Frying oil with flavor score 3 had anisidine and carbonyl values of 150 and 13. 7, respectively. These results suggest the possibility that this organoleptic test can be used to determine the limit for using frying oil. This test may help us to get fried foods with good flavor., 1993, 26, 4, 304, 309, 10.11402/cookeryscience1968.26.4_304

Soybean oil (500g) was heated at 170℃ for 8 hours a day using an electric fryer. Six types (pork fillet, chicken fillet, sardine, Spanish mackerel, sweet pepper or potato) of foods (50g) were deep fat-fried every 4 hours. Frying was continued until the flavor score dropped to 3, which was defined as the rancid point of frying oil. Anicidine value, carbonyl value, acid value and tocopherol content of the rancid frying oil were also determined. The life spans of the frying oils to reach the flavor score to 3 were shorter in meat or fish frying than vegetable frying. The life spans were not significantly different among pork, chicken and fishes in spite of the marked differences in their polyunsaturated fatty acid contents. The chemical scores of rancid oils were similar among all frying oils used for different foods. These results suggest that meats and fishes promote the organoleptic deterioration of frying oils more rapidly than vegetables. The examination of the flavor score of frying oil was suggested to be useful to determine the life span of frying oil., 1996, 29, 2, 104, 108, 10.11402/cookeryscience1995.29.2_104

In the case of burdock and lettuce, which have a high activity of polyphenol oxidase, the radical-scavenging activity and the content of total phenol and chlorogenic acid decreased drastically within 1 min. In the case of broccoli, however, only a small decrease of radical-scavenging activity was observed, and total phenol and chlorogenic acid decreased almost not at all. The decrease of the activity in broccoli depended on the oxidation of ascorbic acid by ascorbate oxidase. None of these compounds decreased after the enzymes had been inactivated by heating.

The intensities of the absorption due to peptide bonds were different depending on the kinds of proteins examined. The absorption of bovine serum albumin at 2170nm decreased by reducing its disulfide (S-S) bonds. The absorption of poly-L-glutamic acid in the a-helix state at 2170nm was stronger than that in the random coil state. These results suggest that the secondary structures of proteins affect the absorption at 2170nm. The extent of contribution of the secondary structures to the absorption intensity was statistically predicted using 9 proteins which have different contents in secondary structures such as α-helix, β-sheet and random coil structures. It was found that the relative extent of the α-helix, β-sheet and random coil structures to the absorption at 2170nm was approximately 2:1:1., 1994, 41, 1, 65, 69, 10.3136/nskkk1962.41.65

Most of the spices showed high 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical-scavenging activity (4-1353μmol Trolox eq./g), peroxy radical-scavenging activity (31-1019μmol Trolox eq./g), and total phenol content (5-1267μmol gallic acid eq./g). Clove was found to have the highest radical-scavenging activity followed by allspice and cinnamon. After heating, both DPPH and peroxy radical-scavenging activities as well as the total phenol content increased in most of the spices. A distinct increase in the activities was found in some spices such as black pepper, red pepper and turmeric. A high correlation coefficient was found between the total phenol content and peroxy radical-scavenging activity., 01 Aug. 2006, 12, 3, 178, 185, 10.3136/fstr.12.178

Fresh oil and the used oil with three degrading degrees (Acid value: about 1, 2 and 4.5) were used in this study. The fried materials (fried batter, maitake tempura and croquette) and frying oil itself were sensory evaluated by the Ranking Method. There were significant differences among the evaluation scores of the oils and of the fried materials prepared with different degrading oils (Kruscal-Wallis test, n=40, P<0.01). In proportion as the oil was degraded the flavor of the fried materials fell off. Sensory evaluation panelists distinguished the quality of fried materials prepared with different degrading oils, but it tended to be difficult to distinguish highly deteriorated oils containing higher than 15% polar compounds (Turkey's method, P<0.05). Fried batter and maitake tempura fried with the oil containing less than 15% polar compounds and the oils themselves were evaluated to be good by the panel. Croquette was rated high when it was fried with the oil containing about 24% polar compounds. When the polar compound content increased higher than 15% level, the evaluation scores of the fried materials tended to lower and the acid value exceeded the standard value to discard the used oil. Therefore, it is our opinion that the measurement of polar compounds is useful in judging whether deep-frying oil is usable or not., 15 Jan. 2004, 51, 1, 23, 27, 10.3136/nskkk.51.23

  【目的】
  奈良漬は、奈良の特産品の一つとして広く知られている高級漬物である。ウリをはじめ、キュウリ、スイカ、ダイコンなどの野菜を6ヶ月から12ヶ月間塩漬けした後、酒粕で数回漬け替えて作られる。キュウリの奈良漬は、「朝風」という品種を用いて製造されることが一般的であるが、昨今、大和野菜の一つである「大和三尺」を使った奈良漬が新たに製造されている。「大和三尺」は、全長30～35cmの長型のキュウリで、果肉は緻密で歯切れがよく、種が少ないことが特徴とされている。本研究では、「朝風」および「大和三尺」を原材料とした奈良漬キュウリの化学的特性、物理的特性および嗜好性を調査することを目的とした。
  【方法】
  奈良市内の製造業者で製造されている「朝風」および「大和三尺」の奈良漬キュウリを試料とした。一般成分として水分、タンパク質、灰分、アスコルビン酸量、嗜好成分としてpH、Brix糖度、塩分、エタノール含量、褐変度を測定した。さらに、機能性成分としてラジカル捕捉活性および総ポリフェノール量、物理的特性として破断特性の測定を行うとともに、官能検査により嗜好性を調べた。また、加工前の生のキュウリについても同様に測定した。
  【結果】
  奈良漬キュウリは生キュウリに比べて高いラジカル捕捉活性を示し、奈良漬に加工するにより機能性を付与できることが明らかになった。奈良漬キュウリにおいて、「朝風」と「大和三尺」の一般成分、嗜好成分、機能性成分に大きな差はみられなかった。しかし、破断特性に違いがみられ、官能検査においても「大和三尺」の方が「朝風」より硬いと評価された。また、「大和三尺」は色が濃く、アルコール風味も強く感じることから好まれない傾向にあった。, 2008, 20, 4, 4, 10.11402/ajscs.20.0.4.0

  方法 奈良市内の奈良漬製造業者６社の奈良漬ウリについて、一般成分として水分、タンパク質、灰分、アスコルビン酸量、嗜好成分としてpH、Brix糖度、塩分、エタノール含量、褐変度を測定した。また、機能性成分としてラジカル捕捉活性および総ポリフェノール量、物理的特性として破断特性の測定を行った。さらに、官能検査により嗜好性を調べるとともに、奈良漬添加クッキーを調製し、奈良漬の製菓適性を評価した。
  結果 ６社の奈良漬ウリにおいて、化学的特性や物理的特性にそれぞれ違いがみられた。ＪＡＳ規格をすべての項目で満たしている奈良漬はなく、それぞれの製造業者によって個性ある独自の奈良漬が作られていることが明らかになった。また、糖分や塩分の少ない奈良漬ウリの方が、ラジカル捕捉活性、総ポリフェノール量および褐変度が高い傾向にあった。官能検査の結果では、酒粕単独で漬けた奈良漬よりも、酒粕に砂糖やみりん粕などを添加して製造された甘口の奈良漬の方が漬物として好まれる傾向にあった。しかし、クッキーに調製することによって奈良漬の嗜好性に変化がみられ、「奈良漬風味」や「サクサク感」の強いクッキーが好まれた。, 2008, 60, 217, 217, 10.11428/kasei.60.0.217.0

  【目的】マイワシは、n-3系高度不飽和脂肪酸であるエイコサペンタエン酸やドコサヘキサエン酸を多く含む良質なタンパク質源である。しかし、その独特な生臭み「魚臭」が魚嫌いの理由となっている。魚臭を抑制する調理法にはさまざまなものが知られているが、その中でもみりん調理に効果があることが知られている。演者らはこれまで、本みりんに含まれるエタノールの共沸作用やエステル類のマスキング効果により、マイワシの魚臭が抑制されることを明らかにしてきた。本研究では、調理した後の保存過程におけるマイワシ魚臭の生成とみりん調理の効果について検討した。
  【方法】購入直後のマイワシ可食部40gをミンチ状とし、水、13%エタノール、本みりん、煮切りみりんをそれぞれ6ml加えて成形した。これらを沸騰水中で煮た後、４℃、２日間保存した。保存した試料について、ヘッドスペースの揮発性成分を固相微量抽出(SPME)で捕集し、GC-MSおよびGC-オルファクトメトリーで解析した。
  【結果】揮発性成分量はいずれの調理条件でも経時的に増加したが、各調味料間において差が認められた。魚臭に関与する揮発性成分のうち、Hexanalや(Z)-4-Heptenal、2,4-Heptadienalは加熱調理により生成量が抑えられる傾向にあった。また、2,3-Pentanedioneや1-Penten-3-olなどは調味料添加により生成が抑制された。, 2005, 17, 101, 101, 10.11402/ajscs.17.0.101.0

• Refereed, International Journal of Environmental Research and Public Health, Levels of Toxic and Essential Elements and Associated Factors in the Hair of Japanese Young Children., Emiko Kusanagi; Hitoshi Takamura; Nobuko Hoshi; Shing-Jen Chen; Mayumi Adachi, There is growing concern regarding the effects of toxic element exposure on the development of children. However, little is known about the level of toxic elements exposure in Japanese children. The purpose of this study was to assess the concentrations of multiple elements (aluminum, cadmium, lead, calcium, copper, iron, magnesium, sodium, zinc) in the hair of 118 Japanese young children and to explore the factors associated with their element levels. The element concentration was analyzed by ICP-MS, and children's food and water intake were assessed by the questionnaire. Results showed that there were no large differences between the level of elements in the hair of Japanese children and those of children in other developed countries. Girls had significantly higher levels of aluminum, copper, and iron (p = 0.000, 0.014, and 0.013, respectively), and boys had a higher level of sodium (p = 0.006). The levels of calcium, iron, magnesium, and sodium in nursery school children were significantly higher than those in kindergarten children (p = 0.024, 0.001, 0.046, and 0.029, respectively). Multiple regression analyses with controlling the confounding variables showed significant negative associations of frequency of yogurt intake with aluminum and lead levels (p = 0.015 and 0.037, respectively). When the children were divided into three groups based on the frequency of yoghurt consumption, viz. L (≤once a week), M (2 or 3 times a week), and H (≥4 to 6 times a week) group, the mean aluminum concentration (µg/g) in the L, M, and H groups was 11.06, 10.13, and 6.85, while the mean lead concentration (µg/g) was 1.76, 1.70, and 0.87, respectively. Our results suggested the validity of hair element concentrations as an exposure measure of essential elements and frequent yogurt intake as a viable measure for protecting children from toxic elements. However, these findings will need to be confirmed in more detailed studies with larger sample sizes in the future., 09 Jan. 2023, 20, 2, 1186, Scientific journal, True, 10.3390/ijerph20021186

• Not Refereed, J. Home Econ. Jpn., 日本家政学会, Change in the radical-scavenging activity of quercetin and epigallocatechin gallate during heat treatment, TAKAMURA Hitoshi; M. Murakami; T. Yamaguchi; H. Takamura; T. Matoba, The effects of heat treatment on the radical-scavenging activity of the two phenolic compounds, quercetin and epigallocatechin gallate, were examined. The retained radical-scavenging activity of both polyphenols was 100% and 80% after respective 60- and 480-min heating at 100℃ suggesting that common boiling practices do not compromise the antioxidation effects. However, the content of epigallocatechin gallate was significantly decreased, although its radical-scavenging activity remained. With heating at 180℃, both the quercetin and epigallocatechin gallate contents decreased much more rapidly than their radical-scavenging activity, suggesting that the radical-scavenging activity remained in their degradation products. After 15 min of heating at 180℃, the retained radical-scavenging activity of quercetin and epigallocatechin gallate was more than 80%. Therefore, usual high-temperature cooking methods such as deep frying or oven heating would not severely compromise the antioxidation effects of these compounds., Mar. 2004, 55, 3, 213-217, 217, False, 10.11428/jhej1987.55.213

  【目的】
  日本調理科学会近畿支部 揚げる・炒める分科会では、今までに家庭での揚げ調理に関して、多様化、健康志向、簡便化が進みつつあることを報告してきた^1）2)。近年メタボリックシンドロームが及ぼす健康障害が広く認知され、健康志向は今後ますます強くなることが予想される。揚げ物は嗜好性が高い一方でカロリー過多を引き起こしやすい料理であるため、使用する油の種類や調理方法への配慮が必要となるが、健康志向の高まりが機能性油の使用や揚げ物の嗜好、家庭での揚げ調理に及ぼす影響は定かではない。そこで今回は、健康に関する意識と使用する油の種類および利用状況の関連性をアンケート調査により明らかにすることを目的とした。
  【方法】
  調査時期：2007年5～6月、調査対象：近畿地区の大学に在学の自宅通学生の家庭（回答者は主調理担当者）、調査法：直接記入法、有効回答数516部（回収率62.7%）
  【結果】
  油の選択基準として「健康によい」を選択した人を「健康志向群(n=249)」とした場合、「非健康志向群(n=267)」に比べて「健康志向群」は機能性油の認知度や健康のために積極的に使用したいと考えている割合が高かった。しかし、機能性油の有効性についての実感は両群共低く、実効性には疑問を感じていることが推察された。また、「健康志向群」は揚げ物の嗜好や作る頻度に差はないが、揚げ物を作る際により油の種類や鮮度に気をつけていることがわかった。さらに、健康な食生活に対する意識およびそれを実行する割合は健康志向群の方が高く、油に対する健康志向と食生活との関連性があることが示唆された。

  【目的】家庭で揚げ調理を行う際に使用した油は環境負荷の軽減や資源の有効利用の観点から繰り返し使用することが望ましい。日本調理科学会近畿支部揚げる・炒める分科会では、揚げ油の使用限界について研究を行ってきた。2002年に近畿地区の家庭を対象として、揚げ油の使用・保存状況を調査した結果、こし方の違いによって、廃油の性状に違いがあることが分かった。これを科学的に検証するために、モデル揚げ調理におけるこし方と揚げ物のおいしさおよび揚げ油の劣化度との関係について、解析を行った。
  【方法】４人分の夕食をモデルとして、フレンチフライドポテト、ミートコロッケ、鶏ささみの揚げ調理を行った。その後、100メッシュ、200メッシュのステンレス製分析用ふるい、油こし紙、クッキングペーパーのいずれかで油こしを行い、揚げ油を１ヶ月間室温で保存した。揚げ油、揚げ物の官能検査をするとともに、各操作段階の油についてカルボニル価、酸価、色、粘度、極性化合物量を測定した。またこし操作を行った後のステンレス製分析用ふるい、油こし紙、クッキングペーパーの表面を電子顕微鏡で観察した。
  【結果】官能検査の結果、揚げ油をこすことによって、揚げ物の味やにおいに対する評価が高くなり、また揚げ油の風味点数、粘度、色のいずれにおいても良い影響が認められた。揚げ油の劣化度には有意な差は認められなかった。またこし方の違いに関しては、いずれも顕著な差は認められなかった。以上の結果より、揚げ調理後の油こし操作は、油の使用限界をのばすことが明らかとなった。

Three types of food were deep fried with or without a batter coating. Sensory tests on the frying oil and fried foods were carried out. The usable life of the frying oil with a batter coating, which is defined as the frying time until the flavor score reached 3, was slightly longer than that for frying without a batter coating ; the oil was less discolored and the scores for "viscosity" and "rancid flavor" were lower with the batter coating. These results suggest that the batter coating prevented the extraction of those components responsible for the color, viscosity and rancid flavor of the frying oil. Fried foods with a flavor score of 3 or more were not considered acceptable for eating. It is suggested that frying food with a batter coating as well as without a batter coating is useful to to determine the life span of frying oil., 2003, 36, 1, 32, 38

Soybean oil was heated at 170℃ in an electric fryer. Two types of food, chicken fillet and potato, were deep-fried with or without breaded batter every 15 min. Frying was continued until the flavor score of the oil had dropped to 3. A sensory evaluation of the frying oil and each fried food was then carried out. The life span of the frying oil to reach the flavor score of 3 was slightly longer with breaded batter than without using the batter coating. The color of the frying oil did not exhibit any degradation, especially when potato was fried. It was difficult to judge the degradation by the appearance of each fried food coated with breaded batter. However, the flavor score of the frying oil corresponded to the flavor score of the fried foods coated with breaded batter. The flavor and taste of the foods fried in the oil with a flavor score of 3 were not good. These results suggest that the flavor score of frying oil is useful to determine the life span of frying oil when a breaded batter coating is used., 2003, 36, 3, 299, 304

Information concerning children's temperament and its expressions in everyday family life were obtained by questionnaire and multiple real-time internet interviews. Results showed gender differences for Negative Affectivity and Effortful Control, but no gender difference for Extraversion/Surgency concerning the effect of family members and the degree of closeness they showed in everyday activities (the latter to be referred to as physical cohesion). Boys were more susceptible than girls to sibling influence. It is suggested that children's temperament is likely to be influenced by the presence of siblings through interactions in daily activities., 2013, 129, 132, Introduction international proceedings

In addition, the levels of metal exposure during the fetal and infancy periods were determined by measuring the concentration of metals in the deciduous teeth enamel of children using ICP-MS. Early childhood exposure to mercury had an adverse effect on the development of children's temperament in school age. Aluminum and lead had an adverse effect on the development of boys’ fine motor behavior in school age. However, there was no effect of metal exposure on brain function development in school age. We found that the nutritional intake of children was associated with the development of throwing ability and cognitive flexibility. Regarding the factors affecting the amount of metal in hair in early childhood, it was revealed that yogurt intake reduced the exposure levels of lead and aluminum., kaken

• Grant-in-Aid for Scientific Research (C), 2005, 2006, 17500539, Suppression of fishy Odor by Cooking with Antioxidant, TAKAMURA Hitoshi, Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, Nara Women's University, 3500000, 3500000, Fish is widely consumed not only in Japan but also all over the world as the source of animal protein. Furthermore, fish is also important as the source of polyunsaturated fatty acids. However, its characteristic odor (fishy odor) often makes fish less acceptable. Though fishy odor has been thought to come from amines such as trimethylamine, the author previously reported that main components of fishy odor are carbonyl compounds and alcohols which are derived from lipids. In this research, a cooking method with antioxidants to suppress the fishy odor was developed. Some mugworts, which are used in Okinawa dishes for suppresion of meat odor, are used for cooking of sardines. Fishy odor components were analyzed by gas chromatography-mass spectrometry (GC-MS), and GC-olfactometry in order to clarify the structures, amounts, and formation mechanism of fish odor components. As the result, mugworts suppressed the formation of carbonyl compounds and alcohols which contribute fishy odor. In addition, mirin, a Japanese traditional seasoning, also suppress the fishy odor. Antioxidants in mugworts and mirin are thought to inhibit the lipid oxidation in sardine., kaken

• Grant-in-Aid for Scientific Research (B), 2004, 2006, 16300236, Design of functional menus by consideration of food combination, MATOBA Teruyoshi; TAKAMURA Hitoshi; YAMAGUCHI Tomoko, Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, 15000000, 15000000, The effects of heating on radical-scavenging activity of vegetables during cooking of minestrone and miso soup were examined. After cooking, the radical-scavenging activity decreased in vegetables and moved to soup. Though seasonings did not affect significantly in minestrone cooking, addition of miso suppressed the release of polyphenols to soup. These results indicate that the radical-scavenging activity in vegetables moved to soup but is stable during cooking. In addition, the radical-scavenging activity in miso is also expected to be effective. The effect of chewing on radical-scavenging activity of. fresh and cooked vegetables were also examined. The radical-scavenging activities of fresh eggplant, green pepper, broccoli, and lettuce decreased by chewing. However, chewing did not affect on the activities of cooked vegetables, which is thought to be due to the inactivation of polyphenol and ascorbate oxidases. Therefore, use of cooked vegetables as the base of functional menus is desirable to avoid the loss of radical-scavenging activity and active compounds and to intake them effectively., kaken

• Grant-in-Aid for Scientific Research (C), 2003, 2004, 15500539, Clarification of fish odor components and suppression by cooking, TAKAMURA Hitoshi, Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, Nara Women's University, 3700000, 3700000, Fish odor is thought to come from amines such as trimethylamine. However, other compounds also contribute to fish odor. In this research, fish odor components were analyzed by gas chromatography -mass spectrometry (GC-MS), and GC-olfactometry in order to clarify the structures, amounts, and formation mechanism of fish odor components. The cooking way to suppress the formation of fish odor was also developed. Sardine was used as the sample fish. The odor components of fresh or deteriorated fish were trapped by solid-phase microextraction (SPME) fiber. Then, the fiber was injected to GC and the odor components were analyzed by GC-MS and GC-olfactometry. In the deteriorated fish, trimethylamine was detected only when the pH of fish sample was higher than 9, suggesting that trimethylamine is not the key compound of fish odor. In GC-olfactometry some carbonyl compounds and alcohols were found to have unpleasant odor. Especially, 2,3-pentanedione, hexanal, 1-penten-3-ol were major. Since these compounds were derived from lipids, it is thought that cooking with foods or seasonings containing antioxidant components can suppress the fish odor., kaken

Epidemiological studies have shown that vegetable consumption is associated with a reduced risk of life-style related diseases. However, reactive oxygen-scavenging compounds present in foods may be affected by cooking procedures prior to consumption. In this work, the changes in reactive oxygen-scavenging compounds in vegetables were analyzed during cooking. First, the changes in ascorbic acid and each polyphenolic compound during cooking of various vegetables were demonstrated. Different polyphenolic compounds had different level of activity, and different interaction with ascorbic acid and tocopherols. Then, it was shown that reactive oxygen-scavenging compounds flowed out to the soup but did not decrease during vegetable soup cooking. In addition, decrease by heating was inhibited by coexistence with other reactive oxygen-scavenging compounds., kaken

Gas chromatograph-mass spectrometry (GC-MS) and gas chromatograph-olfactometry (GC-O) were used for analysis. Head space gas were concentrated by solid-phase microextraction (SPME) method. In the preparation of soybean milk, hexanal predominantly contributed to the beany flavor, however, other lipid-origin compounds also contributed to the flavor. In the heating of soybean oil and soy protein isolate, many compounds other than hexanal contributed their flavor.

• Grant-in-Aid for Scientific Research (B)., 1999, 2000, 11480024, Design of Diet Menu with Free Radical Scavenging Activity and Analysis of Its Availability, MATOBA Teruyoshi; TERAO Junji; TAKAMURA Hitoshi, Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, Nara Women's University, 15700000, 15700000, In this research project, the changes of the free radical scavenging activity and the active compounds in various vegetables during cooking were investigated. In some vegetables, the free radical scavenging activity increased by heating. In other vegetables, the activity decreased or unchanged. Microwave-heated vegetables retained higher free radical scavenging activity than boiled vegetables. In addition, the activity was released to the cooking water. Hence, the menus which utilize cooking water such as soup and stew, and those cooked in microwave oven were recommended to intake free radical scavenging activity efficiently. Among the active compounds, ascorbic acid decreased by heating, especially in boiling. On the other hand, polyphenols such as flavonoids increased in some vegetables and heating conditions. The reason may be the inactivation of polyphenol oxidase by heating, however, the details are now under investigation. These results demonstrate the changes of the free radical scavenging activity and the active compounds in various vegetables during cooking and suggest how to design the diet menu for effective intake of the free radical scavenging activity., kaken

• 奨励研究(A), 1995, 1995, 07780008, 油脂が大豆の酵素的豆臭生成に及ぼす影響, 高村 仁知, 日本学術振興会, 科学研究費助成事業, 奈良女子大学, 1000000, 1000000, 大豆の持つ特異なにおい「豆臭」の主成分はカルボニル化合物の一種であるヘキサナ-ルである。このヘキサナ-ルは大豆に多く含まれるリノール酸からリポキシゲナーゼの作用によって生成する。大豆中には3種類のリポキシゲナーゼアイソザイム(L-1、L-2、L-3)が存在する。リポキシゲナーゼは遊離脂肪酸を基質とするが、大豆種子中に多く含まれる油脂が豆臭生成に及ぼす影響についてはほとんど知られていない。本研究では、この油脂が大豆における豆臭生成に及ぼす影響および機構を解明するため、以下の実験を行った。 大豆試料として、3種類すべてのリポキシゲナーゼアイソザイムを有する通常大豆のほか、全てあるいは一部のアイソザイムを遺伝的に欠損した変異大豆を用い、ヘキサンを用いて油脂を抽出し、脱脂大豆を調製した。こうして得た脱脂大豆から豆乳を調製し、種々の条件でインキュベートを行った。 その結果、通常大豆、およびL-2アイソザイムのみを有する変異大豆由来の豆乳からは、油脂(リノール酸を構成脂肪酸として多く含む大豆油)を添加することにより、ヘキサナ-ルの生成が見られた。この反応機構として、結合型脂質である油脂に直接リポシゲナーゼが作用する場合と、リパーゼなどの加水分解酵素が作用して生成した遊離リノール酸にリポキシゲナーゼが作用する場合とが考えられる。しかし、3種のアイソザイムのうち、L-1やL-3のみを有する変異大豆から調製した豆乳では、油脂を加えることによるヘキサナ-ル生成が見られなかったことから、L-2アイソザイムが直接油脂に作用していると考えられる。従って、油脂はL-2アイソザイムの基質となることによって豆臭生成に寄与していると結論付けられる。, kaken

• 奨励研究(A), 1993, 1993, 05780006, 機器分析による食用油脂劣化度の迅速測定法の開発, 高村 仁知, 日本学術振興会, 科学研究費助成事業, 奈良女子大学, 900000, 900000, 油脂は、栄養学的、食品学的、調理学的に重要な役割を果たしているが、保存時や調理時に酸化や加水分解などをうけることにより劣化しやすく、その結果、食物の風味や栄養価が低下する。この油脂の劣化を定量的に表す指標としては過酸化物価などが広く用いられている。これらの測定は滴定法や比色法などの化学分析法により行われるが、その操作は煩雑で、時間がかかるのが欠点である。一方、機器分析、特に近赤外分光法を用いた食品成分の分析が広まりつつある。この方法は操作が迅速、簡便であるという利点を有しており、主として炭水化物やタンパク質の定量分析に用いられている。本研究では、この近赤外分光法を用いて、食用油脂の劣化度を迅速、簡便に測定する方法を開発した。 性質の異なる種々の食用油脂を、各種の条件で加熱、光照射等を行うことによって劣化させ、劣化度の異なる油脂試料について近赤外分光スペクトルを測定するとともに、過酸化物価を化学分析法により測定した。こうして得られたスペクトルデータと化学分析値について回帰分析を行い、相関の高い波長を選び出して回帰式を求めたところ、過酸化物価と2082nmの吸光度との間に強い相関関係があることを見いだした。また、油脂のヒドロペルオキシドを調製し、これを油脂に加えて測定しても、同様の相関関係が見られたことから、この波長の吸収は、酸化二次生成物ではなく、ヒドロペルオキシドによるものであると考えられる。以上の結果から、近赤外分光法を用いて2082nmの吸収を測定することにより、食用油脂の劣化度のうち、過酸化物価を測定することが可能となった。この近赤外分光法による過酸化物価測定法は迅速、簡便な非破壊分析であるため、操作が繁雑な従来の化学分析法にとってかわることが期待される。, kaken

First, melinjo's effective components, gnetin C, gnemonoside A, and gnemonoside D were fractionated. These had strong bitter taste, and it was supposed that functionality and bitterness of melinjo could not be separated. Then, confectionery and bread using melinjo powder were prepared. Use of 5% melinjo gave confectionery bitterness. Although bread with 30% melinjo could be eaten, its palatability was reduced. Finally, the antioxidative properties of kluwak were analyzed. Phenolic compounds were the main antioxidants in water phase. Gamma-tocotrienol was the main antioxidant in oil phase., kaken

• Grant-in-Aid for General Scientific Research (A), 1987, 1989, 62430023, Roles of Phospholipid Molecular Species in Cell Signaling, KITO Makoto; TAKAMURA Hitoshi; NARITA Hiroshi, Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, Kyoto University, 16400000, 16400000, Roles of phospholipid molecular species in cell signaling were studied. Mass changes in the various molecular species of phospholipids were determined after stimulation of human platelets with thrombin and collagen. Upon stimulation, every molecular species of phosphatidylinositol and phosphatidylserine was equally hydrolyzed, whereas the molecular species of phosphatidylcholine and diacyl- and alkenylacyl-phosphatidylethanolazine containing arachidonic acid were selectively hydrolyzed. The Ca^<2+> concentration affects the differential degradation of phospholipid molecular species in activated human platelets. The thromboxane A_2 antagonist, ONO3708, completely inhibited the increase in cytosolic free Ca^<2+> in human platelets during activation with collagen. Half-maximal Ca^<2+> release and influx required about 3 and 4 nM STA_2, a stable thromboxane A_2 mimetic, respectively. However, half-maximal activation of phospholipase C required about 18 nM STA_2. The Ca^<2+> channel blocker, nifedipine, a dihydropyridine derivative, inhibited the Ca^<2+> influx and release from internal stores caused by collagen or a low concentration of STA_2 (10 nM), but did not inhibit those caused by thrombin or a high concentration of STA_2 (100 nM). These results indicate the presence of two distinct, dihydropyridine-sensitive and insensitive, Ca^<2+> channels dependent on the concentrations and classes of agonists in human platelets. ^<125>I-labeled epidermal growth factor was incorporated into and highly concentrated in endosomes of Chinese hamster V79-UF cells during incubation at 37ﾟC for 8 min after binding to its receptors on the cell surface at 4ﾟC. From the labeled cells, endosomes were isolated by isopyenic centrifugation on a Percoll density gradient and then sucrose density gradients. Endosome membranes were found to differ from plasma membranes in the phospholipid composition. The contents of molecular species of diacylphosphatidyleholine and diacylphosphatidylethanolamine with two monoenoic fatty acids were lower in endosomes than in plasma membranes. The differences in the polar head group and molecular species compositions of phospholipids between endosomes and plasma membranes did not change, regardless of whether or not the proportions of phospholipid molecular species in plasma membranes changed., kaken
