  • To evaluate the prevalence of food allergies and the causative food allergens, 1,469 subjects in various age groups were studied by using a food Allergy questionnaire. Also, specific food antibodies were tested with the MAST method, a chemiluminescent assay, in 84 people who have a positive history of food allergies. The results were as follows : Among the total number of 1,469 subjects, about one- half of the total number(46.6%) have a family history of allergies. According to the questionnaire, the prevalence of food allergies was 11.4%. The group with a family history of allergies showed a higher Prevalence than the group without a family history. Skin allergies were the most common type of food allergies in both groups of male and female subjects. The questionnaire revealed mackerel as the most common food allergen, followed by the allergens of peach, pork, chicken, milk and eggs in decreasing order. According to the MAST allergy test, these diagnosed with an actual food allergy totalled 4.1% of the subjects. Peach and pork were the most common food allergens listed on the MAST results.

  • Cooking, texture and sensory properties of sweet potato Tangmyon (starch noodle), common Tangmyon (50% sweet potato starch+50% corn starch) and corn Tangmyon were evaluated. The weight gain of Tangmyon showed a linear relationship with the square root of cooking time, in which the common Tangmyon showed the highest value. The solid loss during cooking was the highest in common Tangmyon followed by corn Tangmyon. The sweet potato Tangmyon showed the highest value for compression strength and stretching ratio, but lowest value for elongation elastic modulus. At the same compression strength, corn Tangmyon had the highest tensile strength and sweet potato Tangmyon the lowest value. Sweet potato Tangmyon showed the highest sensory scores of gloss, clarity, adhesiveness, gumminess, extensibility and overall desirability, and corn Tangmyon the lowest scores. Except adhesiveness (by appearance) and the gumminess of common and corn Tangmyon, significant differences (p<0.05) were observed for other sensory properties among samples.

  • This study was carried out to investigate the succession patterns of dietary culture and to find out all the educational problems with female college students in both countries as the central figure. The results are as follows. The degree of knowledge acquisition about food of annual custom is 58% in Korea and 72% in Japan. What the rate of knowledge acquisition is high among both countries’ similar food of annual custom are ${\ulcorner}Seolnal(Gantan){\lrcorner}$, ${\ulcorner}Sambok(Doyonohi){\lrcorner}$, and ${\ulcorner}Chuseok(Tsukimi){\lrcorner}$. Cooking experience of festive food is 45% in Korea and 58% in Japan. Among both countries' common festive food what cooking experience is high in Korea are ${\ulcorner}Seolnal{\lrcorner}$ and ${\ulcorner}Chuseok{\lrcorner}$, which are over 97%. In Japan those are ${\ulcorner}Gantan{\lrcorner}$ and ${\ulcorner}Tsukimi{\lrcorner}$, which are over 80%. Regarding learning experience of festive food ${\ulcorner}Seolnal{\lrcorner}$ and ${\ulcorner}Gantan{\lrcorner}$ are beyond 80% and ${\ulcorner}Chuseok{\lrcorner}$ is 88%. In Japan ${\ulcorner}Tsukimi{\lrcorner}$ is 71% and ${\ulcorner}Omisoka{\lrcorner}$ is 85%. The learning sources of food of annual custom are parents and schools in common, and Korea has another learning sources, mass communication. Festive food that is cooked shows much similarity between two countries, but each country has originality. As common food of annual custom ${\ulcorner}Seolnal{\lrcorner}$ has nine kinds of food, ${\ulcorner}Sambok{\lrcorner}$ has three kinds, and ${\ulcorner}Chuseok{\lrcorner}$ has five kinds in Korea In Japan ${\ulcorner}Gantan{\lrcorner}$ has fourteen kinds of food, ${\ulcorner}Doyonohi{\lrcorner}$ has three kinds, and ${\ulcorner}Tsukimi{\lrcorner}$ has five kinds. The successive consciousness about food of annual custom is concentrated on a specific food in Korea. And Japanese consciousness is shown as an expansion-type on diverse food. Korean successive consciousness is 69.4% and Japanese consciousness is 82%. The higher the rate of knowledge acquisition, cooking experience, and learning experience are in both countries, the higher successive consciousness is. So we must note for the importance of home and school’s education.

  • Biological activities of enzymatic hydrolysate of spirulina (EHS) were investigated. EHS showed no significant effects on the growth-stimulating activity for lactic-acid bacteria and antioxidant activity. EHS showed slight in vitro growth-inhibitory effects (15% at 1.42 mg/L) on a human cervical cancer cell line (HeLa). In addition, the anticoagulant activities of EHS were measured based on three different pathways: common, intrinsic and extrinsic pathways. As an indication of anticoagulant activity on common pathway, thrombin time (TT) of EHS (100 mg/L) was measured as 155.6 sec. Activated partial thromboplastin time (aPTT) for intrinsic pathway of EHS (1,000 mg/L) was measured as 95.8 sec. Prothrombin time (PT) based on extrinsic pathway of EHS (1,000 mg/L) was measured as 10.6 sec. These data showed that EHS have influences on anticoagulant factors of common pathway and intrinsic pathway. Consequently it was found that EHS could be used as a functional food for blood circulation.

  • The differences in food consumption between highly educated, married, unemployed and employed women were analyzed by food group and common food item intake, DDS (dietary diversity score), and DVS (dietary variety score) & DVSS (dietary variety score including condiment). In food group intake, the total amount of food intake of the unemployed women (1,554.0 g) were significantly higher than those of the employed (1,477.9 g), while the amount of food from fungi and mushrooms (4.2 g), seaweeds (2.4 g), and fish and shellfish (60.5 g) of the unemployed women was significantly lower than those of the employed. And the amount of meat, poultry and their products (102.8 g), eggs (29.9 g), and animal oil and fats (4.0 g) was significantly higher than those of the employed. Moreover, the common food items of the unemployed women were ranked as eggs (29.7 g), pork (28.9 g), chicken (27.2 g), and beef (26.7 g) at 7, 8, 9, and 10, respectively. When counting the major food groups consumed, DDS=4 has the highest proportion in both groups (unemployed 47.4%, employed 49.1 %). In case of the subjects who had not consumed one particular food group in DDS=4, dairy group was the first (83%), followed by fruit, meat, and vegetables. This order is same in other DDS levels. In dietary variety score (DVS & DVSS), the average number of foods consumed per day of employed women was higher than those of the unemployed. The level of DVSS in the employed women (31.9), especially, is significantly higher than in the unemployed women (30.6). Consequently, highly educated women should pay more attention to increasing dairy intake, and they have need of various foods, over thirty foods without condiments in their diet every day. In addition, encouraging unemployed women to have a nutritionally balanced diet, and offering nutrition education and guidance, such as appropriate choices about animal foods, are needed.

  • This study was performed to quantitatively analyze free amino acids in the bean sprouts of three different merchants by the parts and the cooking methods in order to evaluate the nutritional and sensory values of bean sprouts. Three merchant bean sprouts were analyzed from total, cotyledon and hypocotyls. Aspartic acid was the most common acid isolated from bean sprouts from all three merchants and was found more in the hypocotyls than the cotyledon. On the other hand, arginine, the second most common amino acid, was found more in the cotyledon than the hypocotyls while valine, the third or fourth most common amino acid in total bean sprout, occurred in a greater amount in hypocotyls than in cotyledons. After cooking, was the most concentrated amino acid in the liquid portion of both boiled bean sprouts and bean sprout soup was glutamic acid. Total bean sprouts from merchant C showed significantly higher contents of the most abundant amino acids, such as aspartic acid, arginine, alanine, serine, glutamic acid, isoleucine, leucine and tyrosine (p<0.05). After cooking, bean sprouts from merchant B showed less of a decrease in amino acid content in the solid parts than the products from merchants A and C. In conclusion, aspartic acid was the major amino acid in bean sprouts, regardless of the source, but after cooking, glutamic acid became the most abundant amino acid in the liquid part. Additionally, the pattern of release of the amino acids from the solid beans to the liquid portion during cooking was different with each merchant.

  • Purpose: The clinical interpretation of children sensitized to allergens is challenging, particularly in children with food allergies. We aimed to examine clinical differences between children with monosensitization and those with polysensitization to common food allergens and to determine risk factors for polysensitization in young children <10 years of age with immediate-type food allergies. Methods: The study included children <10 years of age with signs and symptoms indicative of immediate-type food allergies. Serum total IgE level was measured, and ImmunoCAP analysis for food allergens was performed. Results: The mean age of the study subjects was $1.6{\pm}1.6$ years (75 boys and 51 girls). Thirty-eight children (30.2%) were monosensitized and 88 children (69.8%) were polysensitized. Multivariate logistic regression analysis showed that the development of polysensitization to common food allergens was positively associated with a parental history of allergic rhinitis (adjusted odds ratio [aOR], 6.28; 95% confidence interval [CI], 1.78-22.13; P=0.004), season of birth (summer/fall) (aOR, 3.10; 95% CI, 1.10-8.79; P=0.033), and exclusive breastfeeding in the first 6 months of age (aOR, 3.51; 95% CI, 1.20-10.25; P=0.022). Conclusion: We found significant clinical differences between children with monosensitization and those with polysensitization to common food allergens and identified risk factors for the development of polysensitization in young children with immediate-type food allergies. Clinicians should consider these clinical risk factors when evaluating, counseling, treating, and monitoring young children with food allergies.
