  • In order to observe the effects of resistant starches on human glycemic response, nine female university students were investigated using cellulose (CED), resistant starch 3 (RS3D) and resistant starch 4 (RS4D) diets. Each woman's blood sugar and insulin, triacylglycerol and free fatty in plasma concentration were measured at fasting state, then 15, 30, 45, 60, 75, 90 and 120 minute after each test diet feeding. Glycemic indices of the Cellulose diet (CED: 57.9 $\pm3.00$), the Resistant starch 3 diet (RS3D: 52.6 $\pm7.9$) and the Resistant starch 4 diet (RS4D: 52.9 $\pm10.2$) were similar to each other, but they were significantly lower in comparison with those of white wheat bread diet (WWBD: 100). Insulinemic indices of the CED (49.8 $\pm8.2$), RS3D (50.0 $\pm7.3$) and RS4D (72.4 $\pm7.7$) were significantly lower in comparison with the white wheat bread diet (WWBD: 100), but among the dietary fiber diets, the insulinemic index of RS4D was significantly higher than the CED and the RS3D. Plasma triacylglycerol contents of the CED, RS3D and RS4D including WWBD showed gradual increase in tendency after lowering in early stage of each test diet feeding, but not significantly different in each dietary fiber added diet. Plasma free fatty acid contents of the CED, RS3D and RS4D including WWBD showed gradual decrease in tendency after each test diet feeding, but not significantly different by each dietary fiber added diet. In above results, we speculate that resistant starch 3 controls rapid elevation of blood sugar by delaying intestinal digestion and absorption of cellulose, but the result appears to be different from RS4 in comparison. Thus, RS3 intakes may contribute to the diet therapy of diabetic humans, but more studies on RS4 is needed in the future. (Korean J Community Nutrition 9(4): 528∼535, 2004)

  • This study was conducted to examine how the Jewish nation, which disappeared in the history, has come to history again after 2000 years, considering the investigation of the Pentateuch from old testaments in the bible that might be recorded from B.C 1446 to 1406 about 3440 years ago. The foods in the era of the Pentateuch were classified by a strict rule which stipulated eatable clean foods and uneatable unclean foods. According to the Pentateuch, Israelites must not have blood, and the rule has still influenced them strongly. Sacrificial rites were classified into five categories: burnt offering, grain offering, peace offering, sin offering and guilt offering. The subdivisions of the seasons were Passover, Festival of Unleavened bread, Festival of First fruits, Festival of Harvest, Festival of Trumpets, Day of Atonement, Festival of Shelters; and those seasons were explained clearly by their meanings and even methods. Contrary to general food culture instructed by custom and tradition, the commandments transcribed the food cultures for the Food Sanitation Act in themselves long ago. Those commandments even remark the results brought to the observant and the disobedient stringently.

  • The rheological prouerties of dough were evaluated the dough added whole wheat flour during breadmaking. From the farinogram, water absorption of the dough was decreased as the amount of coarse whole wheat flour was increased. While water absorption of the dough was increased as the amount of fine whole wheat flour was increased. Arrival time and development time of the dough with coarse whole wheat flour were longer than those of fine whole wheat flour. As the amount of whole wheat flour was increased, the weakness was increased. Weakness of coarse whole wheat flour was higher than that of fine whole wheat flour. From the extensograph, extension and resistance to extension were decreased with increasing the amount of whole wheat flour. Resistance to extension of coarse whole wheat flour was higher than that of fine whole wheat flour. From the amylograph, as the amount of whole wheat flour increased, maximum viscosity was decreased gradually. Though the amount of coarse whole wheat flour and fine whole wheat flour was increased up to 30% and 50%, respectively, external characteristics of bread was remained in normal. As the amount of whole wheat flour was increased, the value of whiteness was decreased.

  • Imago's flight activities of Protaetia brevitarsis were from mid June to early September, and those of Allomyrina dichotoma were from mid June to late August. These activities were mainly influenced by amount and duration of rain. They were more active when there was small amount and short period of rain in a year. Distribution depth of the 3$^{rd}$ larvae of P. brevitarsis were not affected to the temperature. But A. dichotoma were sensitively react to the temperature, almost larvae were near the surface when high temperature. The distribution of P. brevitarsis was not affected by humidity, but most of A. dichotoma were near the surface when high humidity. Larvae of P. brevitarsis usually ate their dead individuals. When we supplied as food the pork, chicken, fresh mackerel, bread, apple, and pear. They took all of these food but larvae of A. dichotoma took only bread. Two species were lived in similar environment but those feeding habit was very different.

  • The rheological properties of dough made with 0% 1 % 2% or 3% Corni fructus flour were investigated Rapid Visco Analyzer (RVA) analysis showed that the initial pasting temperature increased with increasing Corni fructusflour content, while the peak viscosity decreased. The water absorption, stability, development time, elasticity and valorimeter value of the dough, as determined using a farinograph and alveograph, decreased with increasing amounts of Corni fructusflour, while weakness increased. The extensibility, fermented volume and consistency of the dough increased gradually with increasing Corni fructus flour content. These results indicate that the addition of Corni fructus flour affects the rheological properties of bread.

  • This study investigated eating behaviors of high school students (209 males and 230 females) in Daegu region by gender. As a result of analyzing breakfast intake frequency, 'Not rarely eat' showed the highest (25.1%), followed by '5 times a week' (24.4%), '2 times a week' (17.3%), '3 times a week' (15.0%), '1 time a week' (11.6%), and '4 times a week' (6.6%). Regarding reasons for skipping breakfast, 'lack of time' showed the highest percentages. For their breakfast, 53.5% of students ate boiled rice with side dishes. Regarding reasons for skipping breakfast, 'buy and eat snack' showed the highest percentages. Regarding favorite breakfast menu, 'rice roll, rice ball, rice burger' showed the highest percentage (55.4%), followed by 'bread & cereal' (28.7%) and 'fruits & vegetable' (7.7%). Regarding purchase of breakfast alternatives, 'Yes' was highest. Considering actors for choosing a breakfast alternative, there is a need for 'convenience of food consumption', 'spending less time', 'easy cooking', 'favorite menu' and 'taste' of the breakfast alternative. When asked how much they like breakfast alternative menus, they responded that they liked 'rice roll, rice ball, rice burger' (3.91), 'bread & cereal' (3.67), 'fruit & vegetable' (3.66), 'noodle' (3.39), 'porridge' (3.18) and 'rice cake' (3.07). This result shows that breakfast menus should be developed according to high school students preferences.

  • The purpose of this study was to explore dietary patterns and compare dietary patterns using cluster and factor analysis in Korean adults. This study analyzed data of 4,182 adult populations who aged 30 and more and had all of socio-demographic, anthropometric, and dietary data from 2005 Korean Health and Nutrition Examination Survey. Socio-demographic data was assessed by questionnaire and dietary data from 24-hour recall method was used. For cluster analysis, the percent of energy intake from each food group was used and 4 patterns were identified: "traditional", "bread, fruit & vegetable, milk", "noodle & egg", and "meat, fish, alcohol". The "traditional" pattern group was more likely to be old, less educated, living in a rural area and had higher percentage of energy intake from carbohydrates than other pattern groups. "Meat, fish, alcohol" group was more likely to be male and higher percentage of energy intake from fat. For factor analysis, mean amount of each food group was used and also 4 patterns were identified; "traditional", "modified", "bread, fruit, milk", and "noodle, egg, mushroom". People who showed higher factor score of "traditional" pattern were more likely to be elderly, less educated, and living in a rural area and higher proportion of energy intake from carbohydrates. In conclusion, three dietary patterns defined by cluster and factor analysis separately were similar and all dietary patterns were affected by socio-demographic factors and nutrient profile.

  • This study was carried out to investigate rheological properties of bread dough by adding hydrocolloids such as arabic gum, pectin and carboxyl methyl cellulose (CMC). 0.2% and 0.5% of each hydrocolloid were added to the dough. Farinograph, pH of dough, extensograph, fermometer and amylograph were analyzed. In farinograph, water absorption rate of dough was increased by adding hydrocolloids and the highest water absorption resulting in 70.8% was shown by adding 0.5% of CMC. Dough development time increased but stability decreased. pH of dough was lowered by adding hydrocolloids and pH of dough with 0.5% of pectin was the lowest. In extensograph, resistance of dough decreased but extensibility increased and R/E value lowered. In fermometer, $CO_2$ gas production increased and dough with 0.2% of CMC showed the largest gas production. In amylograph, initial gelatinization temperature increased by $0.5-1.5^{\circ}C$, but temperature for maximum viscosity was lowered by $1-1.5^{\circ}C$ and maximum viscosity was increased.

  • The purpose of this study was to assess the iron nutritional status of college women residing in the Kyungin area. The anthropometric parameters, nutrient intake, and biochemical status of iron were measured for 102 college women. The mean height and weight were 160.3cm and 52.4kg, respectively. The proportion of subjects whose BMI was less than 20 was 41.3%. The proportion of subjects assessed as overweight(25$\geq$25%) assessed by the fat percent(FP) was 53.9%. The mean daily intake of iron was 13.90mg(77.1% of RDA), composed of 0.97mg of heme iron and 12.44mg(69.0% of RDA). When the sources of iron were grouped as rice(including bread), noodle, soup, side dish, and snack, noodle provided, 3.95mg of iron regarded as the highest amount. Subjects were taking 6.72mg(51.4% of RDA) of iron per day from main dishes(rice, bread and noodle). The fifty five percent of the subjects showed iron depletion(serum femitin<20ng/ml)and 33.4% showed suppressed erythropoiesis with iron deficiency(serum ferritin<10ng/ml). The anemic subjects assessed with transferrin saturation (<15%) represented 33.3% of the test population, whereas 11.8% of the subjects possessed less than 12g/dl of hemoglobin. Subjects not satisfied with their body shape were having significantly lower amount of energy intake(p<0.05) than the subjects satisfied with their body shape. College women having mothers who graduated from university had a significantly decreased amount of energy, carbohydrates, fat and vitamin C(p<0.05). The mean RBC and serum iron of the subjects who were on a diet more than one month were lower than those of the subjects who were not on a diet(p<0.05).
