  • The effects of phytase and cellulase treatment on the bioavailability of iron, calcium, and zinc in whole wheat flour and their food applications were evaluated in this study. Whole wheat flour was treated with phytase and cellulase either individually or in combination and incubated at 50℃ for 2 h; the concentrations used for the individual enzymes were 2%, 10%, and 20%. The concentration of the combination enzyme was 20% with a mixing ratio of 5:5. Total dietary fiber and phytate contents were reduced as the concentrations of phytase and cellulase increased. The bioavailability of iron, calcium, and zinc was notably improved after in vitro digestion in 20% cellulase, combination enzyme, and 20% phytase, respectively. Muffins made with cellulase- and phytase-treated whole wheat flour showed improved quality and bioavailability of minerals. Phytase- and cellulase-treated whole wheat flour may be useful for development of functional food products with improved bioavailability of minerals.

  • The objective of this study was to investigate stability of traditional starch sizes according to time. The properties of wheat flour and fermented whole-wheat flour were studied. And comparison of stiffness, tensile strength, air permeability, whiteness, and surface observation of cotton fabrics sized with wheat flour and fermented whole-wheat flour before and after 12-years were examined. The amylograph data indicated that ISF-W(Isolated starch flour- white) have good pasting properties than NWF(Natural wheat flour) and ISF-B(Isolated starch flour- light brown). The cotton fabrics sized with ISF-W had higher tensile strength and whiteness, and lower stiffness and air permeability than those of NWF as the time takes 12 years. We identified the stability of traditional starch size using scanning electronic micrograph.

  • A Comparative study was performed among five Korean wheat(Greu, Eunpa, Tapdong, Allgreu, Woori) and three imported wheat(Dark Northern Spring, Austrian Standard Wheat, Western White) to investigate the characteristics of minerals and phytate from Korean wheat varieties. Ash contents of kernel was higher in Korean wheat than in imported wheat and related to ash contents and darkness of flour. More contents of Fe, P, and Mg from Korean wheat grains and Fe from Korean wheat flours were observed in comparison to imported wheat varieties. Fe concentration in Korean flour show high, indicating Fe was distributed at endosperm layer of kernels and not eliminated with milling. In addition, phytate affecting availability of minerals was determined from kernels and flours. Even though Korean wheat kernels had more phytate than that of imported wheat kernels, it is believed that most of phytate was removed with milling and there was no major difference between Korean and imported wheat flours. We also observed that the content of phosphate closely parallels the content of phytate from both the flours and kernels.

  • The study was conducted to investigate the effect of whole-wheat ratio and nutrition information provision on purchasing behavior and consumer intention among individuals in their twenties who lack calcium intake. In the end, this study aims to provide basic data on the development and marketing strategy of customized nutrition-reinforced snacks. Regarding whole wheat ratios, the acceptance of taste of whole wheat flour was highest in ZF but didn't seem significant difference with HF's. The familiarity of taste and flavor (P <0.001), purchase intention (p <0.001) and recommendation intention (p <0.001) were higher in order of ZF, HF and TF. Regarding information provision, familiarity of taste and flavor (P <0.05), purchase intention (p <0.05) and recommendation intention (p <0.05) were higher in order of detailed information group, non - information group and simple information group. Therefore, developing calcium-fortified biscuit, mixing whole wheat flour with normal flour might reduce consumer's resistance, Also, providing detailed information on the degree of fortification of calcium and dietary fiber might cause a synergistic effect on consumption.

  • The present study aimed to investigate the effect of whole wheat cookie supplemented with Capsosiphon fulvescens (CF) extract on serum glucose homeostasis in C57BL/6 mice. This study examined whether the same effect was demonstrated for whole wheat cookie in comparison to previous research documenting the glucose-lowering effect of food products combined with CF extract. Mice were divided into three groups depending on the diet administered: normal cookie (NC), whole wheat cookie (WC), and WC blended with CF extract (WCFE). After 4 weeks of administering the experimental diet, the blood glucose level, serum insulin level, and homeostatic model assessment for insulin resistance index were found to be significantly lower in the WCFE group than in the NC and WC groups. These results suggest that whole wheat cookie containing CF extract is effective in preventing insulin resistance and maintaining blood glucose homeostasis.

  • The aim of this study was to compare the physicochemical properties of domestic and imported commercial plain wheat flour and dough. Four types of domestic wheat flour (DW; DW1-4) were compared to four types of imported wheat flour (IW; IW1-4). DWs exhibited lower moisture content, lightness (L), and whiteness, and higher protein content, redness (a), and yellowness (b), than those exhibited by IWs. Solvent retention capacity of DWs and IWs was similar; however, DWs showed higher gluten performance index. Pasting properties, analyzed by rapid visco analyzer (RVA), were similar for DW1, DW2, and IWs; however, DW3 and DW4 showed different RVA patterns. Considering that DW3 and DW4 were organic wheat flour, possible incorporation of damaged kernel might increase amylase activities resulting in decreased peak viscosity. Dough resistance (108.4-159.9 g) and extensibility (11.8-16.7 mm) of IWs were higher than those of DWs (78.0-118.7 g, 8.7-12.5 mm, respectively).

  • This study investigated the brewing properties of rice beer made with yeast isolated from traditional whole wheat nuruk. The experimental method was followed by alcohol fermentation and quality analysis for six months after separating the yeast from nuruk. The yeasts isolated from traditional nuruk showed normal fermentation characteristics, like those of commercial yeast, in terms of alcohol production capability, sugar content, and pH reducing power. Especially, the yeast (KCCM 301) isolated from whole wheat nuruk showed higher contents of glycogen and trehalose than that of commercial yeast, and so KCCM 301 yeast has excellent yeast vitality. Meanwhile, the yeast (KCCM 90301) isolated from traditional Nuruk produced significantly higher alcohol and ester contents than that of commercial yeast. This has a positive effect for supplementing the taste and aroma of rice beer. In conclusion, the yeasts isolated from whole wheat nuruk showed the general alcohol fermentation pattern and aroma content of rice beer. These yeasts seem to be effective in strengthening the flavor of rice beer.

  • To obtain the oil sesame, walnut, whole wheat, and rice bran were extracted for 1, 3, or 6 hr by a shanking water bath(35$^{\circ}C$ and 100 rpm), and by soxhlet extractor(80$^{\circ}C$) for 1, 3 or 6 hr, respectively. The highest yield of extracted oil was obtained from the walnut(63.07% weight) and the whole wheat showed the lowest extraction yield of oil(1.13% weight). Major fatty acids from the extracted oils were linoleic, oleic, and palmitic acid. The maximum contents of total phytosterol in sesame, walnut, whole wheat, and rice bran were 0.44, 1.57, 2.25, and 2.03(% weight), respectively. Besides, total tocopherol contents in sesame, walnut, whole wheat, and rice bran were maxima 3.42, 0.16, 2.92, and 0.07(% weight), respectively. From the extracted oils, structured lipids(SL) were synthesized by the interesterification reaction with conjugated linoleic acid(CLA) in a shanking water bath at 55$^{\circ}C$. When the reactions(1:3 substrate molar ratio, extracted oil:CLA) were conducted for 24 hr, maxima 23.75 mol% of CLA incorporation was obtained from walnut oil and, in other cases, 16.28 - 19.15 mol% of CLA was found in the produced SL triacylglycerol molecules.

  • 웰빙문화의 영향으로 하얀 쌀밥에 흑미, 찹쌀보리, 콩, 조, 밀 등 여러 잡곡을 섞어 먹는 혼식이 확산되고 있다. 국내에서 개발된 품종 중 '신미찰1호'는 전분 중 아밀로스 함량이 낮고 찰기가 있어 백미에 혼합하는 통밀 쌀로 이용한다. 하지만 겉이 빨개 일부 소비자들이 꺼려하면서 겉을 깎아내고 사용해 영양 면에서 좋지 않았다. 이에 따라 국립식량과학원에서는 취반용에 적합하면서 겉이 하얀 백립계 찰밀 '백찰'을 개발하였다.
