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

Soybean flour, sodium alginate, soybean-based fiber, and plant oil were used to produce a gel by cross-linking with calcium ion after freezing. The resulting gel was frozen again and thawed, followed by infiltration of soy protein solution to form a layered-porous structure. 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

  • 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

  • Refereed, JOURNAL OF FOOD SCIENCE, WILEY-BLACKWELL, Effects of Grilling on Total Polyphenol Content and Antioxidant Capacity of Eggplant (Solanum melongena L.), Kentaro Uchida; Haruo Tomita; Toshikazu Takemori; Hitoshi Takamura, Cooking can change the polyphenol contents of eggplant. 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

  • Refereed, Food Science and Technology Research, Japanese Society for Food Science and Technology, Development of bread supplemented with the silk protein sericin, Tayori Takechi; Hitoshi Takamura, The present study aimed to develop sericin-added bread in an effort to promote the effective consumption of the silk protein sericin and to evaluate bread-baking performance with sericin addition, with respect to effects on bread structure and palatability. 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

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

The taste quality and texture related to stickiness, firmness and mealiness were evaluated. Among the varieties, there were significant differences in the taste quality of the two kinds of steamed dishes, but there were no significant differences in the taste quality of the boiled dish and that boiled in miso soup. There were significant differences among varieties in every texture assessment with all cooking methods. There was a positive correlation between the assessment for taste quality and the texture related to mealiness with all cooking methods., Apr. 2009, 42, 2, 129-134, 134, 10.11402/cookeryscience.42.129
  • Science of Cookery, The Japan Society of Cookery Science, Effects of carbonyl compounds for judging the deterioration of frying oil, Research group on Frying-cooking group Kinki branch office The Japan Society of Cookery Science, The effects of carbonyl compounds on flavor score as an index for the deterioration of frying oil was investigated. 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

  • 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.

  • Refereed, JOURNAL OF FOOD SCIENCE, BLACKWELL PUBLISHING, Analysis of volatile flavor compounds of sardine (Sardinops melanostica) by solid phase microextraction, N. Ganeko; M. Shoda; I. 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

  • 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

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

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.

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. Among these assays, the DPPH-HPLC method was shown to be the best since the liposome oxidation method is affected more by the structure of phenolic compounds than the DPPH-HPLC method., Mar. 2002, 67, 2, 539, 541, Scientific journal

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 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.

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

  • Journal of Cookery Science of Japan, The Japan Society of Cookery Science, Studies on the Life Span of Frying Oil (III):Comparison of the flavor score of frying oil with the evaluation of fried foods, A collaborative study was designed to assess the applicability of a sensory test to determine the life span of frying oil. 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

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

(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
  • Journal of Cookery Science of Japan, The Japan Society of Cookery Science, Studies on the Life Span of Frying Oil (II) : Effects of Frying Materials on the Deterioration, A collaborative study was designed to examine the applicability of a sensory test which determines the life span of frying oil. 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

Jpn., Characterization of Local Preference of the Tste by the Inspection of " Udon Dashi-Jiru" along Tokaido, TAKAMURA Hitoshi, We collected 110 samples of Udon dashi-jiru (the soup for Japanese wheat noodles) prepared by various restaurants in 12 cities along Tokaido to clarify the local difference of the preference of the taste. 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

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.

Jpn., Relationship between the Molecular Structure and Deep Fat Frying Properties of Edible Oils, TAKAMURA Hitoshi; Masami Kimura; Hideko Harigaya; Tamie Yanagisawa; Hitoshi Takamura; Teruyoshi Matoba, The relationship between the molecular structure and such deep fat frying properties of edible oils as oil absorption, dehydration, and oil drainage were investigated during deep fat frying by various monoacid-triacylglycerol molecular species and edible oils. 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 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
  • Journal of Cookery Science of Japan, The Japan Society of Cookery Science, Studies on the Limit for Using Frying oil(I) : The Results from a Collaboration on the Flavor of Frying Oil and Fried Potato, A collaborative study was designed to examine the applicability of an organoleptic test which determines the limit for using frying oil. 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

The substrate specificity for other aldehydes and the participation of coenzymes (NADH and NAD^+ ) in this reaction were investigated. A soybean extract was incubated with various aliphatic aldehydes (carbon number 3-9) at 37℃,and the amount of alcohols formed was determined, The enzyme had a wide substrate specificity ,the enzyme activity decreasing as the carbon number of the aldehydes increased (carbon number enzyme activity decreasing as the carbon number of the aldehydes increased (carbon number enzyme activity decreasing as the carbon number of the aldehydes increased (carbon number3>4>5>6>7>9>8).The enzyme activity was markedly promoted by the addition of NAD^+ as well as NADH. When a soybean extract was incubated with NAD^+,NADH was formed ,but no NADH was formed in the soybean extract after heating at 100℃for 5 min. These results suggest that NAD^+ was converted to NADH the action of an enzyme(s) in the soybean extract., Mar. 1992, 43, 3, 193-198, 198

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.

  • Not Refereed, J. Home Econ. Jpn., 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

  • Journal of cookery science of Japan, Studies on the Life Span of Frying Oil (V) : Flavor Score of Frying Oil and Fried Foods with Breaded Batter, Inoue Sachiyo; Ishizu Hideko; Fujimura-Ito Tomoko; Oshika Junko; Kajimoto Goro; Takei Yoko; Takamura Hitoshi; Nakahara Mitsuko; Nishiike Tamako; Hayashi Yoshimi; Hara Tomoko; Fukami Yoshiko; Fukui Hiroko; Matoba Teruyoshi; Mizuno Chie; Murakami Megumi; Yaku Fumiko; Yukawa Natsuko, A collaborative study was designed to examine the applicability of a sensory evaluation to determine the life span of frying oil. 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
  • Journal of cookery science of Japan, Studies on the Life Span of Frying Oil(IV) : comparison between Fryin with and without a Batter coation., A collaborative study was conducted to examine the applicability of a sensory test to determine the life span of frying oil. 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

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), 01 Apr. 2015 - 31 Mar. 2019, 15K00863, Development of added value enhanced bread by effective use of familiar Food containing functional ingredients, TAKECHI Tayori; SHIWA Mutsumi; HARA Yasuka, Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, 4680000, 3600000, 1080000, In this study, we aimed to develop bread with high added value by effectively using the functional ingredients of food.
    Throughout the study period, we examined the baking conditions (examination of gluten substitutes, water temperature, etc.) in gluten-free rice flour bread preparation. As a result, 1.It was possible to develop allergy-responsive (high value-added) bread by using fruit juice residue. Moreover, the directionality of the preparation method which raised the viscosity of dough and raised bread making property was able to be found only by the examination of the water temperature by the component derived from rice flour.
    As to 1., the research results were summarized and submitted to a domestic journal., kaken
  • Grant-in-Aid for Scientific Research (C), 28 Apr. 2011 - 31 Mar. 2015, 23500927, Development of Foods with Functionality and Palatability of Indonesian Vegetative Food Materials, TAKAMURA HITOSHI, Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, Nara Women's University, 5330000, 4100000, 1230000, Foods with functionality and palatability of Indonesian vegetative food materials, melinjo and kluwak were developed. 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 Scientific Research (B), 01 Apr. 2011 - 31 Mar. 2014, 23330208, An interdisciplinary study of the change in children's temperament from three cohorts over twenty years, with references to potential influencing factors on temperament, KUSANAGI Emiko; HOSHI Nobuko; ADACHI Mayumi; TAKAMURA Hitoshi; CHEN Shing-jen; OISHI Tadashi, Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, Kokugakuin University Hokkaido Junior College, 10010000, 7700000, 2310000, Questionnaires, real-time internet interviews and analysis of metals contained in children's hair were conducted to investigate the change of temperament of three cohorts of children, differences of temperament in kindergarten vs daycare center children, and potential effects of psychosocial and environmental chemicals on temperament. Questionnaires result showed no significant difference in children's temperament between 1992 and 2002, while children's temperament in 2002 showed some peculiarities as compared with that of children in other cohorts. Children of daycare centers were found to be higher on Extroversion/Surgency than kindergarten children. Results from internet interviews and questionnaires indicated that the presence or absence of siblings, and the physical closeness in family life were determinants of temperament. Significant relationship between children's temperament and mothers' dietary habit during pregnancy and current dietary habit of children were also found., kaken
  • Grant-in-Aid for Scientific Research (B), 01 Apr. 2011 - 31 Mar. 2014, 23300272, How does ecological cooking affect food functionality and palatability ?, MATOBA Teruyoshi; KITAO Satoshi; ANDO Mami; TAKAMURA Hitoshi, Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, Kansai University of Welfare Sciences, 18590000, 14300000, 4290000, This research was accomplished to propose the right "ecology cooking" that can maintain functionality and palatability in order to realize the eco-friendly eating habits. Foods were cooked to get the similar hardness by several cooking procedures. CO2 discharge was calculated for each procedure, and the functionality and palatability of cooked foods were determined. Microwave oven cooking tended to decrease CO2 discharge compared to gas. However, microwave cooking with salt or soy sauce tended to increase CO2 discharges compared to other seasonings., kaken
  • Grant-in-Aid for Scientific Research (C), 2008 - 2010, 20500683, Development of cooking method to enhance palatability and functionality of fish, TAKAMURA Hitoshi, Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, Nara Women's University, 4680000, 3600000, 1080000, In order to develop the cooking method to enhance the palatability and functionality of fish, the changes of flavor and functional components in fish were analyzed during cooking with vegetable condiments containing antioxidants, which suppress the formation of lipid oxidation products. Cooking with vegetable condiments decreased volatile compounds due to lipid oxidation. Though cooking without vegetable condiments decreased antioxidant activity, cooking with vegetable condiments increased antioxidant activity. These results suggest that cooking with vegetable condiments enhances palatability and functionality of fish., 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
  • Grant-in-Aid for Scientific Research (B), 2001 - 2003, 13480028, Analysis of Changes in Reactive Oxygen Acavenging Compounds durin Cooking, MATOBA Teruyoshi; TAKAMURA Hitoshi; TERAO Junji, Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, Nara Women's University, 15700000, 15700000, Foods, especially vegetables, contain a wide variety of reactive oxygen-scavenging compounds such as ascorbic acid and polyphenols. 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

  • Grant-in-Aid for Scientific Research (C), 2000 - 2001, 12680130, Formation of Lipid-Orgin Compounds during Processing and Cooking of Soybean Foods and Their Effects on Flavor, TAKAMURA Hitoshi, Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, Nara Women's University, 4000000, 4000000, In this research project, the formation of lipid-origin compounds during processing and cooking of soybean foods and their effects on flavor were investigated. 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. Though most of the compounds were thought to be derived from lipids, some of them may be from other food components., kaken
  • 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), 1998 - 1999, 10780080, 調理過程における油脂過酸化物の分解と毒性アルデヒドの生成に関する研究, 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, 2100000, 2100000, 油脂に含まれる高度不飽和脂肪酸は、食品の加工や調理の過程で酸化されやすく、その結果、油脂過酸化物が生成する。油脂過酸化物はさらに食品中の他成分と反応する過程で分解や重合をおこし、2次生成物が生ずる。また、油脂過酸化物やその代謝物は毒性を示し、老化や発ガンの原因ともなる。しかし、実際の食物においては多くの食品成分が共存しており、また、さまざまな調理操作が加えられるため、油脂過酸化物の挙動については明らかではない。本研究では、実際の食物における油脂過酸化物の分解とこれに由来する毒性アルデヒドの生成について、各種の食品成分や調理操作による影響をも含めて明らかにすることを目的に研究を遂行している。本年度は、油脂過酸化物として、リノール酸13-ヒドロペルオキシド(13-HPOD)を用い、油脂(トリカプリリン)中における13-HPODの分解をHPLCで追跡した。その結果、13-HPODの半減期は油脂中50℃で約50時間、100℃で約3.8時間と、水中(8.3時間、0.8時間)より安定であった。揚げ調理で用いられる170℃では半減期約10分と速やかに分解した。酸化防止剤として一般的に用いられるBHT(プチルヒドロキシトルエン)とα-トコフェロールとでは13-HPODの分解に与える影響が異なっていた。それぞれ13-HPODに対し等モル量添加した場合、BHTは13-HPODの分解を抑制(100℃、170℃で半減期4.4時間、18分)し、α-トコフェロールは分解を促進(22分、5分)した。分解反応の活性化エネルギーは水中、油脂中、BHT存在下、α-トコフェロール存在下で、それぞれ、13.9、13.3、14.9、14.5kcal/molとほぼ同程度であった。今回の研究では毒性アルデヒドの生成に関する明確な知見は得られなかった。, kaken

  • 奨励研究(A), 1996 - 1996, 08780011, 近赤外分光法による食品中の水分の迅速定量法の開発, 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, 水は、食品においてもっとも多く存在する成分であり、その含有量は食品の性質を左右する。しかし、その定量法として一般的に用いられている乾燥法は、時間がかかる、正しく水分が測定できているとは言えない、などの欠点を有する。そこで、本研究では、近年、その食品分析への利用が広がりつつある近赤外分光法を用いた、迅速・簡便、かつ正確な食品中の水分定量法の開発を試みた。
    まず、各種親水性溶媒に水を加えて濃度系列を作成し、近赤外スペクトルを測定し、水由来の吸収ピーク波長における吸光度と水分含量との間で回帰分析を行ったところ、ジメチルスフォキシド、ジメチルホルムアミド、ジメチルアセトアミドを用いた場合に高い相関が得られた。次に、水分含量の異なるでんぷんからこれらの溶媒で水分を抽出し、その近赤外スペクトルを測定し、乾燥法で得られた結果との間で回帰分析を行ったところ、ジメチルホルムアミド、ジメチルアセトアミドを用いた場合に高い相関が得られた。また、でんぷんの種類を、可溶性、馬鈴薯、サツマイモ、トウモロコシ、小麦と変えても、得られた回帰方程式の定数項および回帰係数に大きな差は見られなかった。さらに、でんぷん以外の粉末食品(シクロデキストリン、小麦粉、上新粉、餅子、黄粉、ココア、脱脂粉乳、胡椒)についても同様の実験を行ったところ、ほぼ同様の結果が得られた。
    以上の結果から、本法は一般的に広く用いることのできる、新しい水分定量法となりうることが示唆された。とくに、飯粒などのペースト状の食品や、ココアなどの脂質含量の高い食品のように、乾燥法では測定が困難である食品について有用な手法であると考えられる。, 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

  • 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
