The purpose of this study was to investigate not only quality characteristics such as overrun, meltdown and sensory evaluation of oligosaccharide-supplemented soy ice cream but also physiological effects of ice cream with soy and/or oligosaccharide on blood sugar and lipid profile in streptozotocin-induced diabetic rats. Powder of parched soybean was added at $7.6\%$ replacing skimmed milk and cream, soybean oil at $7.6\%$ replacing milk oil in cream, and fructooli-gosaccharide at $9.5\%$ replacing sucrose on weight basis. Five kinds of ice cream were prepared: MMS (skimmed milk, milk oil, sucrose), MMO (skimmed milk, milk oil, oligosaccharide), SSS (soybean, soybean oil, sucrose), SSO (soybean, soybean oil, oligosaccharide), and BSO (black soybean, soybean oil, oligosaccharide). Overrun and meltdown of soy ice cream were significantly lower than those of milk ice cream. Scores of sensory evaluation especially in mouth feel and melting feel in mouth were lower in soy ice cream. Freeze-dried ice cream was supplemented to AIN93-based diets at $30\%$(w/w). Sprague-Dawley male rats with diabetes induced by injecting streptozotocin were fed experimental diets for 4 weeks. Plasma glucose level was significantly lowered in SSO group compared with MMS group. Plasma insulin levels of MMO and SSO groups were not significantly different from that of normal group, while those of MMS and SSO group were significantly lower than normal group. Plasma cholesterol was decreased in groups fed ice cream supplemented either soybean or fructooligosaccharide compared to MMS group. HDL-cholesterol level was elevated and triglyceride was decreased significantly in MMO group compared to MMS group. LDL-cholesterol levels of SSS and BSO groups and liver triglyceride level of SSO group were significantly lower compared to MMS group. In conclusion, oligosaccharide-supplemented soy ice cream lowered blood sugar, and ice cream supplemented with soybean and/or oligosaccharide improved lipid profile in diabetic rats.

The comparison soy protein coagulation by heat-and enzyme-treatment are summarized. The gelation mechanism of glycinin by heating was mainly due to dissociation and aggregation of the basic subunit of 11S globulin. In case of 7S globulin, macro-soluble aggregates may be formed by noncovalent intraction more than 30min at 8$0^{\circ}C$. Whereas, coagulum occured by the microbial enzyme was more minuter than the other Ca-, HCI-coagulum. Heat treatment attacked the basic subunit of 11S globulin and this results agreed very, how-ever, preferred acidic subunit to basic subunit of 11S globulin and attacked the 7S globulin, that could produce coagulum products within 4~5min at $65^{\circ}C$.

Composite films were prepared with soy protein isolate (SPI) and various clay minerals by casting from polymer and clay water suspension. Effects of clay minerals on film thickness, moisture content (MC), tensile strength (TS), elongation at break (E), water vapor permeability (WVP), and water solubility (WS) were tested. Properties including thickness, surface smoothness, and homogeneity of films prepared with organically modified montmorillonite (O-MMT), Wamok clay (W-clay), bentonite, talc powder, and zeolite were comparable to those of control SPI films. TS increased significantly (p<0.05) in films prepared with O-MMT and bentonite, while WVP decreased significantly (p<0.05) in bentonite-added films. WS of most nanocomposite films decreased significantly (p<0.05).

Soy protein isolate (SPI) films were supplemented with cinnamaldehyde (CA) at concentrations of 0.1-0.5 mL/5 g SPI. The effects of CA on film color, tensile strength (TS), percent elongation at break (E, %) and water vapor permeability (WVP) of SPI films were investigated. Generally, total color difference (${\Delta}E$), WVP, and TS of SPI films increased gradually, while E and TSM decreased significantly (p<0.05) as the amount of cinnamaldehyde in the SPI films increased. Cinnamaldehyde can be used as a potential cross-linking agent for preparing SPI films by improving mechanical strength and water resistant properties.

This study was carried out in order to estimate the residual amount of mercury in soy-bean sprouts in each steps of cooking. Samples were taken at markets and also cultured at home without applying the mercury containing pesticides as control. Mercury was determined by dithizone method. It was disclosed that soy-bean sprouts purchased at markets contained $1.32{\pm}0.274ppm$, 13 times as high as the maximal allowable concentration of mercury in food recommeded by Ministry of Health and Social Affairs. Mercury contents, however, dropped off steadily by steps of cooking: rinsed with distilled water and boiled in distilled water showing concentrations of $0.11{\pm}0.025ppm$ in boiled sprouts and $0.03{\pm}0.022ppm$ in sprout-soup. These values were not statistically different from those in control samples, and not exceeded the maximal allowabled levels of mercury in food. It can be concluded that the use of mercury containing pesticides in the cultivation of soy-bean sprouts is not so serious problem as it has been suspected in respect of food contamination, but careful attention must be paid to indiscriminate use of mercury containing pesticides as they may contaminate air, water and soil and secondarily bring harm to human health through food chains.

This study researched the food culture and bean economy of the Joseon dynasty during the 16th century and according to the primary lifestyle reference "Shaemirok (?尾錄)". The research analyzed the textual contents of the "Shaemirok (?尾錄)". It is clear that the people of the Joseon dynasty produced more beans than grain, at a ratio of 41 to 50, respectively. The soy bean sauce consumption was split into family consumption and non-family consumption. It was evident that there was more family consumption compared to that of non-family consumption at a ratio of 7 to 3, respectively. People of the Joseon dynasty annually recorded their way of making soy sauce from 1595 to 1600. The Joseon writers edited the record six times for making meju and four times for making soy sauce. The recorded ratio displays the ingredients of soy sauce, which were: 6 Du of Mal Jang and 2 Du of salt. Mal Jang and salt had a three to one ratio, respectively. The most mentioned food was Tofu during the mid-Joseon period with fifty six mentions. The Joseon people regarded making Tofu in a Buddhist temple as a family-bonding experience. Porridge was the second most prominent food next to Tofu, among the bean-related food. Porridge appears thirty five times. There were 3 types of porridge named: bean porridge, bean powder porridge and mung bean porridge.

The purpose of this study was to determined the rate of sensitization to food allergen in children with Atopic Dermatitis (AD) in Korea. A total of 3,783 patients (male = 1983, female = 1800) with AD (age under 18 years) who had visited Samsung Medical Center from 1998 to 2003 were enrolled in the study. Food hypersensitivity was measured by specific IgE to egg, cow's milk, soy, peanut, wheat, buckwheat, beef, pork, chicken, shrimp, crab, salmon, mackerel, etc. Specific IgE levels > 0.7 kU/L. by Captured Allergen Product (CAP) assay were considered positive. Chi-square test at p value < 0.05 was used to examine the difference of the prevalence by sex and age. The rate of sensitization to multiple food allergens was 31.2% and decreased with age. Hypersensitivity to egg showed highest prevalence, which was 24.3%, compared to the prevalence of other foods. High prevalence of hypersensitivity to milk. wheat, soy, peanut, crab or shrimp was observed (11.6- 17.7%). Low prevalence of hypersensitivity to beef, pork, tuna or chicken was observed (1.9-3.5%). Children aged under 3 years had significantly higher prevalence of hypersensitivity to egg, milk, soy and beef than children aged at least 3 years. Our results stress the need for examination of food hypersensitivity aimed at identified and limited each food allergen among children with AD caused by food to help patients outgrow their food allergy.
