This study was designed to investigate the effective ratio of healthy bread wish green tea powder. The weight. volume, and colon difference of bread with various contents of green tea powder were measured. And the picture of bread and the panel test were taken. To avoid the decrease of volume, the experiment was taken with active gluten. The weight to bread was increased and the volume was decreased significantly according to increase of green tea powder ratio. But, the volume of the group with active gluten(3%+ and 4%+) was higher than that of the group with green tea powder 2%. That is which the correction of the volute was taken by active gluten in green tea powder bread. In the result of panel test and volume measurement. addition of 3% green tea powder was appropriate, and the addition of active gluten corrected the decrease of volume. Therefore. using the green tea powder, the diversity of bread by functionality, nutritional composition. taste, color. flavor of green tea powder can be developed. This result will support the background the development of green tea bread of good quality.

This study was conducted to investigate the effects of different active gluten and rice Nuruk(Asp. oryzae, Asp. kawachii rice Nuruk) levels on the quality properties of steamed rice breads. Enzyme(amylase and acidic protease) activity of Asp. oryzae rice Nuruk is higher than Asp. kawachii rice Nuruk. Among the loaf volume of active gluten that were tested (10, 13, 15 and 17%) an active gluten loaf volume of 15% produced the best steamed rice bread. As a result of the loaf volume test steamed rice bread with rice Nuruk was decreased than steamed wheat bread. Regarding color, all treatments produced significant differences. The L value was decreased in steamed rice bread more than in steamed wheat bread, and a and b values were increased, respectively. Hardness, gumminess and chewiness of SRB-2, 3, 4 were lower than SWB-1 but springiness were higher. According to the sensory evaluation of steamed rice bread, color, flavor, and uniformity of pores were the highest in the steamed wheat bread, and the chewiness and texture were good in the steamed rice bread containing added active gluten and rice Nuruk. In this study, addition of rice Nuruk in steamed rice bread did not increase loaf volume, but had an advantage for overall desirability.

In this study, we compared corn gluten hydrolyzates, BCAAs, and leucine for their effects on body weight reduction in high fat-induced obese rats in order to determine the major active components in the corn gluten hydrolyzates. After obesity was induced for 13 weeks with high fat diet, the overweight-induced SD rats (n = 64) were stratified according to body weight, randomly blocked into eight treatments, and raised for 8 weeks. Four groups were changed to a normal diet and the other groups remained on the high fat diet. Each of the groups within both diets was fed either casein, corn gluten hydrolyzates, leucine, or branched chain amino acids, respectively. Daily food intake, body weight gain, and food efficiency ratio were significantly lower in the corn gluten hydrolyzate groups compared to the other groups, regardless of the high fat diet or normal fat diet. The rats fed the corn gluten hydrolyzates diet had the lowest perirenal fat pad weights whereas muscle weight was significantly increased in the corn gluten hydrolyzates groups. Plasma triglyceride, hepatic total lipid, and total cholesterol contents were significantly reduced in the corn gluten hydrolyzates groups. Other lipid profile measurements were not significantly changed. Plasma triglyceride and hepatic total lipid were also significantly reduced in the BCAA and leucine groups. Leptin levels were significantly lower and adiponectin was significantly higher in the corn gluten hydrolyzates groups. Fasting blood glucose, insulin, C-peptide, and HOMA-IR levels were also significantly reduced in the corn gluten hydrozylates groups, regardless of fat level.

쟈스민차의 비율을 달리하여 제조한 쟈스민차 식빵의 무게, 부피, 색도를 비교하고 사진을 촬영하였으며, 관능평가를 실시하여 효과적인 배합비를 찾고자 하였으며, 식빵에 식이섬유가 다량 함유된 부재료를 첨가하는 경우 부피가 감소하여 제빵적성이 감소하므로 본 연구에서는 쟈스민차가루를 첨가하여 색과 향을 살리면서도 부피의 감소를 방지하기 위해 활성 글루텐을 첨가하여 비교 실험하였다. 쟈스민차가루 첨가량이 증가함에 따라 식빵의 무게는 점차 증가하였으며(p<0.05), 쟈스민차가루를 첨가한 식빵의 부피는 첨가비율이 증가함에 따라 유의적으로 감소하는 경향을 보였다. 활성 글루텐 첨가에 의해서는 유의적인 부피의 보정은 이루어지지 않았다. 쟈스민차가루를 첨가한 식빵 내부의 색도는 쟈스민차가루 첨가량이 증가함에 따라 명도(L)는 현저하게 낮아졌으며, 적색도(a)는 쟈스민차가루를 첨가함에 따라 높아지는 경향을 나타내었고, 황색도(b)도 쟈스민차가루 첨가에 따라 점차 높은 값을 나타내어 쟈스민차 첨가 시 내부 색은 어두워짐을 확인할 수 있었다. 관능검사 결과 맛과 풍미, 색, 조직감 모두 대조군을 제외하고는 2％, 3%군이 유사하게 높아, 전체적인 선호도는 쟈스민차 가루 2％, 3％, 3%+군이 유의한 차이 없이 대조군에 이어 높게 나왔다. 이상의 결과를 종합할 때 쟈스민차가루의 첨가량은 3%가 적절한 것으로 나타났다. 따라서 식빵 제조시 쟈스민차가루를 이용함으로써 쟈스민차가루의 기능성과 영양성분, 맛, 색, 향을 이용하여 제품의 다양성을 살릴 수 있다고 사료되며, 이 결과는 우수한 품질의 쟈스민차빵 개발의 기초자료가 될 것으로 생각된다.e correlation between self efficacy and controllability. Particularly, there was a significant negative relationship between self efficacy and external controllability. Based upon these results, it is recommended that the developing nursing interventions to change causal attribution and self-efficacy is necessary. A number of theoretical relationships and empirical finding are confirmed by this data, and future proposals in research is suggested. 따라서 교사들의 관심유형과 실행수준에 따라 수행평가에 대한 지원을 달리함으로써 교사들의 관심도와 실행수준을 향상시켜야 할 것이며 보다 효과적인 수행평가가 실시되도록 해야 할 것이다.. 결론적으로 현재 우리나라에서는 갈색 정도의 차이 문제이지 갈색란을 좋아함을 알 수 있었고, 교육에 의해 조금씩은 고정 관념을 바꿀 수 있는 가능성을 확인할 수 있었다.ique impact at 0.70 km/s and 0.91 km/s were compared with experimental results and Eulerian hydrocode CTH simulation results.

The dietary fiber alginic acid has no nutritional value; however, it decreases the utilization of nutrients by the body and can prevent obesity, hyperlipidemia, arteriosclerosis, constipation, and colon cancer. The low-molecular-weight alginic acid polymannuronate improves serum and liver lipid metabolism by decreasing cholesterol levels in high-cholesterol groups and may be used to control high blood pressure. Previously, we showed that polymannuronate, a physiologically active agent from seaweed, has a lipid-lowering effect and preventative role in colon cancer. In addition, the differentiation of polymannuronate-treated adipocytes was inhibited, triggering decreased leptin expression. This study examined ways to increase dietary satisfaction with and improve the nutritional quality of polymannuronate using hamburger buns supplemented with polymannuronate. Twenty male Sprague-Dawley rats were divided into two groups: the control group was fed hamburger buns containing 6% gluten, while the experimental group was fed hamburger buns containing 6% gluten and 10% polymannuronate. The serum triglyceride, phospholipid, and total and free cholesterol levels of the rats in the experimental group were decreased compared with those of the controls. The serum aspartate aminotransferase activity levels did not differ between the two groups. This study demonstrates that polymannuronate has beneficial effects on lipid metabolism and may be commercially useful.

This study is carried out to investigate the effect of any periods in the freezer and the product of value, moisture content, baking loss, specific volume loaf in manufncturing process thereof. The moisture content of the croissant slightly decreased as the periods passed in the freezer. And as passed periods frozen croissant dough dried naturally by the freezer fan. 1. As frozen periods passed croissant dough decreased moisture content and loaf volume. The volume is relation to the molsture content and croissant dough' gluten. Yeast is active but croissant dough is dried so pastry margarine's moisture vaporized little by little. 2. 1 day frozen bench time provided maximum specific loaf volume while croissant shape was unsettled, moisture content was highest. At the same dough croissant hardness had very sofi crust. 3. 1week and 2weets frozen dough had specific loaf volume and hardness with proper crust color. As the proper bench time provided best shape of croissant, color. 4. 4weeks and 8weeks frozen dough had over-al] value of croissant accelerating older product. As the same result, over Sweets frozen periods product were not available for sale and serving to customers. 5. By the sensory evaluation tests, over-all croissant as 1 week, 2weeks were significantly higher quality those than 6. 1day, 4weeks and 8weeks. Textural properties of croissant over 4weeks frozen periods so hard for every panel. According to the study, not croissant dough but also any other frozen dough(ex.Danish, brioche etc.)have to need proper bench time and 1week or 2weeks circulation making method have to given encouragement to practical pastry industry. Add to this study using only for frozen dough yeast instead of using fresh and instant
