This study was attempted to establish the basic data for effective utilization of the dried radish and sweet potato. The rehydration characteristic was carried out from these dried root vegetables in various conditions. The following results were obtained. The rehydration value was increased in glycine solution, whereas it decreased in lactic acid solution. Also the vacuum freezing was higher than that in hot air drying, and it was higher the slow freezing than in the quick freezing. The rehydration rate and the rehydration surface area curve were composed of three stages, and these stages were corresponded to each other. At the range of initial immersion to 2min. , the largest rehydration rate was showed. The activation energy obtained from the Arrhenius plot of the rehydration rate constant(K) were 3.8×10 exp (3)㎈/g ㏖ and 3.7×1010 exp (3)㎈/g ㏖ for dried radish and sweet potato, respectively.

The purpose of this study is to prove the propriety of prolongation in educational term of department of food and nutrition at junior college in Korea in order to improve the quality of dietitian by giving substantial education. The prolongation of educational term from two to three years is necessary to cultivate a more excellent dietitian because of the following three reasons. First, the freshmen in junior colleges are poor in basic scholastic ability which is needed for the study of nutrition science. Second, many new subjects which will support the new rolles of dietitian, in acordance with social changes, should be supplemented in curriculum. Third, the subject of spot-practice for dietitian should be established as a regular course in curriculum.

The purposes of this studies were to investigate the effect of dietry Se levels and alcohol administration on the lipid hyperoxidation and the lipid metabolism in the rat. Seventy two male rats of Sprague-Dawley Strain weighting about 58∼62g were divided into 12groups. The dietary Se levels were 10, 0.4 and 0㎎, and the dietary α-tocopherol levels were 150 and 0㎎ per ㎏ diet, respectively. Alcohol-administrated groups received drinking water solution containing 10% of ethanol from the 3-weeks of experimental periods. The obtained experimetal results are summarized as follows. 1. Food intake, body weight gain and food efficiency ratio were significantly lower in H-, L- and alcohol administrated groups(-A) by administrated Se and alcohol in diet. The weight of liver and spleen tended to be greater in H- and alcohol administrated groups. 2. The glutathione values in liver tend to be lower in alcohol or Vit. E administrated groups than nonadministrated groups. Also there were higher in H- and L- than C-groups, but the increasing range decreased due to administrated alcohol. The lipid peroxide values in liver were significantly higher in alcohol groups, and L- and tocopherol groups were higher values. Specially the increasing of lipid peroxide values were significantly effected by alcohol in low Se and Vit. E groups. 3. The contents of total glyceride in plasma were higher in alcohol groups, there were significantly higher values in alcohol administrated groups under low Se and Vit. E groups. The contents of total cholesterol and HDL-cholesterol in plasma were significantly higher in alcohol groups. 4. The contents of total lipid in liver were higher alcohol groups, and slightly higher values in low Se groups(L-groups) than other groups, also higher values in low Vit. E groups. Those of total glyceride in liver were significantly higher in alcohol groups, appeared highest values when alcohol was administrated in low Se and Vit. E groups. The increasing of total glyceride content was significantly effected by alcohol in low Se groups than that in C-groups.

This survey was carried out to investigate the effect of the daily average nutrient intakes, self-consciousness of nutrition knowledge and health on the nutrition knowledge and food habits between college women and their own mothers. Questionnaires were completed by 214 college women who do major in nutrition and by 173 their mothers. The college women scored significantly higher than that of their mothers in the nutrition knowledge. And their mothers scored significantly higher than that of college women in the food habits. Most of the subjects belonged to `Fair` food habit group. which was considered to be relatively good. The correlation of the scores between nutrition knowledge and food habits of the college women and their mothers was low. The daily average nutrient intakes of all women were higher than the recommended dietary allowance except for that of Iron. There was a significant and negative correlation between the nutrition knowledge score and daily average nutrient intakes in college women. But there was not a significant correlation in the nutrient intakes in their mothers. And also there was a significant and positive correlation between food habits score in their mothers but there was not a significant correlation score in college women. The higher the women had a self-consciousness of health. the higher their mothers had a food habit score, but they had daily average nutrient intakes were lower than their daughter`s(college women). And the women that had a self-consciousness of health were healthier. daily nutrient intakes in their own mothers were higher in the food habits scores than that of the college women. The main curriculum for a good food habits is that it is important that one has a responsible nutrition education. For the improvement of nutrition education program we should transmit the nutritional information through an effective mass media(i.e. Radio, TV, Newspaper).

This survey was carried out to investigate the effects of dietary attitude on the nutrition knowledge, food habits, the daily average nutrient intakes and the intake of instant food, convenience food & fast food between college women and their mothers. Questionaries were completed by 214 college nutrition majors and also by their mothers numbering at 173. College women`s mothers showed a better average in meal time regularities per week than that of. college women. Also it is the fact that the college women had a higher frequency rate of instant food and fast food than their mothers. In the case of both college women and mothers if they eat at regular meal times they had a higher score in food habits. But the daily average nutrient intakes was not significant because of the fact that the meal time regularity and nutrient intakes did not concide. The higher frequency of instant food intake had a lower score in food habits and nutrition knowledge. The higher frequency of fast food intake had a higher food habits score but it also had a lower score in nutrition knowledge. As in the intake of instant food and convenience food the college women had a higher intake frequency. In the dietary pattern the college women they liked to eat flour foods. But their mothers liked to eat Korean foods. The selective motive and the degree of satisfaction of food service industry product was for convenience and time saving. The food service industry products were found to be unsatisfactory in nutrition and sanitation. Therefore we must be more aware of preventing the disappearance of Korean traditional foods. For the continuing development of our dietary culture we need to have the food service industry to develop more suitable diet for Korean.

In order to study the extraction mechanism of barley tea, some factors affecting extraction and physical properties of roasted barley and extract were examined. The main results of this study are as follows : 1. The roasted barley particles used as the raw materials were amorphous. Under the extraction condition used the average swelling ratio of the particles and imbibed volume were 1.39 and 1.65㎖/g respectively. The maximum soluble solid content in the roasted barley was 67.07%. 2. The concentrations of the barley extracts were determined by measuring their optical densitis at 420㎚ and the relationship between the concentration(C) and optical density(O. D. ) was expressed as : C = 6.178×O. D. As shown in the following relationship, the viscosities (μ: Ns/㎡) of barley extracts were influenced by concentration(C : ㎏/㎥) and temperature(T : ℃ ). μ=5.6731×10 exp (-4) e^(2.7×10 exp (-3)×C) μ=3.577×10 exp (-3) e^(-3.02×10 exp (-2)×T)
