  • High dietary phytate is a known factor in reducing the bioavailability of minerals such as zinc and calcium which are already chronically low in the Korean diet. This study was conducted to develop methods for reducing dietary phytate through the addition of phytate and/or the substitution of high phytate foods with low phytate foods. Ten units of phytase per 100g of uncooked brown rice were added to brown rice gruel resulted in a 16.2% phytate reduction after a 3-hour incubation period; an 18.2% reduction was produced after a 6-hour incubation period. The addition of ten units of phytase per 100g of soybean curd residue at 45$^{\circ}C$, followed by refrigeration for 3 hours, resulted in a 19.1% phytate reduction. The addition of 20 units of phytase under the same conditions reduced phytate content by 24.6%. In this study, two typical Korean meals consisting of legumes and unrefined cereals were prepared as high phytate meals; these were then compared to low phytate meals that had been prepared by treating the foods with phytase and substituting unrefined with refined cereals (i.e., brown rice with white rice, whole wheat bread with white bread). The phytate content of the two high phytate meals was 1878.2mg and 1811.8mg. After the addition of phytase and the food substitution, the phytate content of the low phytate meals was reduced to 788.9mg and 606.0mg. The phytate to zinc molar ratio of high phytate diets was 22.4 and 21.3 and 9.4 and 7.9 for the low phytate meals. These results indicate that the nutritional status of Koreans in terms zinc and other minerals can be improved by phytate reduction. This can be accomplished through the change of milling process for some cereals and/or the enzyme treatment of some high phytate food items.

  • A study was carried out to compare the daily foods which were eaten during $14{\sim}19$ century among Korea (Chosun dynasty), China (Ming, thing dynasty), and Japan (Muromachi, Edo era). Specially, in Ming, Ching dynasty, Noodles and dumpling were cooked very often and in Muromachi, Edo era, many kinds of beans were used so much, and there were many kinds of steamed rice to compare with Korea and China. Also, in Japan at these era Woodong, Morisoba, and Somyen were used as favorite foods harbitually. 1. The crops were used as staple foods in three countries such as steamed rice, gruel, noodle, dumpling, rice cake etc. commonly. 2. In Chosun, a roe deer, deer, antelope, and wild boar were more favoite dishes than cow, chicken, and dog, generally people enjoyed to eat pork and chicken. In Ming Ching, pork, chicken, goose, dove, lamb, ass, and duck were used as food materials, also wild animals such as deer, rabbit, and monkey etc. were used. In Muromach era, wild animal as racoon dog, otter, deer, antelope, bear, were used as food materials, in early Edo era (Yayoi and Momoyama), beef and pork were used as daily foods but they were eaten decreasingly in Edo era. So in Japan at those era, the dishes prepared of fishes were more than those of meats. For example, Sushi was made from that time, people all over the world are enjoying to have Sushi at present time. 3. Also in these era, many kinds of vegetables and fruits were used in three countries, and new kinds of vegetables and fruits were introduced from foreign countries, for example, red pepper, pumpkin, sweet potato, potato in Korea, corn, sweet potato, red pepper in China, and water melon, pumpkin, corn, red pepper, marmellow, sweet potato, sugar beet in Japan.

  • A special form of questionaire was prepared and distributed to 502 housewives in seoul from Feb. 8th to 22nd in 1989. The results were as follows: In Cooking methods, they tended to follow in the steps of their mother, and it took about half an hour or an hour to prepare a meal. They cooked fried foods once or twice a month. Whenever they fried foods they need new oil. Followings were details of cooking method mainly used by housewives. Fishes were tended to be roast, vegetables to be dressing and seasoning. Highly milled boiled rice was best preferred as the cheif food, and it was cooked by following procedure; First rice was washed, and steeped in water for the time being. Next, the water was poured out and water was filled again, then rice with the water was boiled. Fish Chige was cooked in the way that fish was put into the boiled soup. Fermented sao-bean paste Chige was cooked using water in which rice had been washed. Hard-boiled beef with soy sauce was made using the method that soy sauce was properly poured after beef was boiled. A Spinach was boiled shightly with salty water. In view of those results, there were many cases that housewives did not only utilize their knowledge about foods in real dietary life, but also fell short of endeaver to do so. They chiefly made use of the cooking methods instructed from their mother or husband's mother. In conclusion, in order to illuminate housewives to have an exact nutritional knowledge about foods and cooking methods getting out of the loss of nutritions, nutritional education program must be provided for housewives.

  • This study aimed to investigate the perception, consumption, and acceptability of convenience mealsin low-income female elderly attending a lunch program at a community well fare center. Using in-depth interviews, qualitative data were collected 11 elderly females ($62.5{\pm}11.2y$) living in Seoul. Participants tried to eat various foods in small-portionsat home, although they ate out what they were offered. Elderly females preferred lunch box-type meals containing a bowl of rice served with toppings, gruel, or Bibimbop due to the growing unavailability of cooking or preparing a meal. Side-dish type convenience mealswere also preferred among elderly females since boiled rice can be easily prepared according to individual preferences. In addition, participants preferred healthy foods. Convenience meal planning and production, appropriate kinds of foods, cooking methods, menus, and packaging should be selected based on the elderly's functional atrophy in chewing, swallowing, digestion, and metabolic diseases. Furthermore, food preferences and comfort foods among the elderlyneed to be identified and characterized. Therefore, more information, including bite size, cutting size, and food texture, should be provided to understand and develop convenience meals for the elderly.

  • Food habit, eating-out pattern, smoking and drinking habits of 814 elderly (aged over 60) living in Incheon were surveyed by questionnaire. The ratio of the elderly who have balanced meals at moderate amount was slightly higher in urban area. Urban elderly tended to have mild foods, while rural elderly preferred hot and salty foods. Score for food habit was higher in urban elderly and there was no difference between male and female elderly. Most urban elderly had their meal at the public facilities for elderly, while most rural elderly used general restaurant and public room for elderly. Korean foods were the most favorite menu when ate out. Ratio of elderly who have difficulties in chewing was 21.2 and 39.6% for urban and rural elderly, respectively. Many elderly, especially more than 70% of female elderly, prepared the meals for themselves. Rural elderly smoked and drank more than urban elderly and male elderly did more than female elderly.

  • This study was performed to investigate the perception and preferences regarding commercial universal design foods (UDF) made with different ingredients. A one-to-one interview was used for data collection and the survey was conducted on 41 elderly people (over age 65; males: 11, females: 30) attending senior welfare centers in Seoul. Twelve UDF samples were collected, which were widely sold in Japan. Majority of respondents prepared meals (53.7%) and ate alone (43.9%), respectively. The preferred cooking level of elderly food was "ready to eat (RTE)" (43.9%) or "ready to heat (RTH)" (43.9%) rather than fresh cut product. In most, the elderly had no problem with chewing-action (90.2%). Generally, food ingredients such as grain, meat, seafood and fruits showed higher preference than vegetable and nuts. Among 12 UDF samples, pumpkin gratin (4.17) and peach flavored jelly (4.27) showed higher preferences among tested samples on a 5-point facial hedonic scale. There were no significant differences in overall preferences of all samples by difficulty in terms of chewing and swallowing of respondents. Demi-glace sauce hamburger and pot sukiyaki were more preferred as age increased (p<0.05).
