자화수의 조리용수로써 기능에 대하여 연구한 결과 다음과 같은 현상을 관찰하였다. 1. 자화수의 pH의 변화는 수도수, 생수 공히 자화수가 약간 알칼리성을 띄었으며 시간이 지남에 따라 수도수에서는 pH가 유의하게 감소하고 생수에서는 증가하였다. 2. 건조식품을 불림에 있어 자화수의 경우 수도수를 사용한 경우보다 수화율이 유의적으로 높게 나타났다. 자화수에 침수한 버섯의 경우 초기부터 수분 흡수율이 약간 높았으며 90분 이후부터는 유의적으로 높아졌다. 콩은 하루밤 방치후 자화수에 침수한 시료에서 유의적으로 흡수율이 높게 나타났다. 3. 표면장력의 변화는 자화수의 표면장력이 수도수에 비해 작았고 시간의 경과에 따라서 유의하게 감소하였다. 4. 염장식품을 수침한 경우 자화수에서 특히 초기침수 5분 이내에 염장물로부터의 염분 유출량이 유의적으로 많았다.

An individual's eating behavior reflects not only the eating habits of past but also the type of them which characterize the next generation's. A great difference had been observed between western and oriental food lifestyle. By the frequent contacts with each other, however, current oriental food lifestyle is apt to be much westernized. But the food culture of Chosun tribe in Yenbeun, in spite of natural, local, cultural and social demographical factor of change, has been almost preserved in basic convention for 140 years. It can be observed in choice, acceptance and fixation of food that the management of traditional food and eating behavior has been subtained preserving their unique tradition in Chosun tribe.

The objective of this study was to access the effects of sensory and physical properties of Beandaeduk on 7 different combination methods (three were combined with mung bean and different proportions of water; four were combined with mung bean and various cereals with constant water), and 3 storage periods (0, 1 and 3 weeks at -18℃). This experiment was consisted of sensory evaluation I (appearance, texture, taste, flavor and overall preference), II (color, moisture, volume, hardness, elasticity, viscosity and ratio materials, off-flavor and oder) and physical analysis of each sample, and questionaire survey of Beandaeduk. In sensory evaluation I except flavor, significant differences (p〈0.05) were found among different combination methods of sample. Also significant differences (p〈0.05) were found in sample for storage periods, except appearance. In sensory evaluation II, only moisture and oder of samples were significantly different (p〈0.05) for storage periods, and there were significant differences (p〈0.05) in samples among different combination methods, except elasicity. Stepwise regression for storage periods in sensory I showed that texture and taste were important factors in overall preference of sample. In the questionaire survey, preference and adding materials of Beandaeduk were different according to province. Half of respondents preferred to get instant Beandaeduk and instant mung bean powder.

This study was conducted to research on the nutritional status of vegetarian boys high school students, to keep abreast with the international trend of stressing the vegetarian diet, thereby analyzing the degree of the influence of their dietary habit on their growth. The object of the study were 62boys high school students who are lacto-ovo vegetarians, and the author adopted three popular research methods. questionaire physical test and blood test Though vegetarian diet is helpful for the prevention of coronary and heart diesedse of the adults, but it is not enough for the students who are needed lot of protein and calorie.
