The Purpose of this study was to investigate the food preferences of college students of Korea. The survey was conducted on november, 1981 through the questionnaires. The subjects were 1184 male and 1241 female students of 9 universities. The results obtained were summarized as follows : 1) Preferences of staple foods : Cooked rice was preferred most by the subjects. Male liked rice more than female, whereas female liked bread and noodle more than male. Among the different kinds of rice, bread, and noodles, the following food items were favored by the subjects. (plain rice, red bean rice and soybean rice ; salad bread and vegetable bread ; Nangmyun and Bibim Kooksu). The foods not preferred were barley rice, instant noodle and soybean milk noodle. 2) Preference of side - dishes : Among the kinds of side - dishes by different preparation methods, stews were the most favored and the next favored were soups by the subiecls whereas female showed lower preference of soups than male subjects Most disliked kinds of side-dishes were changachi and moochim. For example, side-dishes which showed higher preference in each preparation method were stew (Kimchi stew and Soybean paste stew), soup (Beef soup and Seaweed soup), kimchi (Korean cabbage Kimchi), Bockeum (Sauted beef and Sauted Kimchil, cheon(Beef Cheon, fish Cheon), Kui(broiled saury and broiled yellow tail runner), Chorim(braised cuttle fish and braised fish cake), Namul(sliced radish, cucumber, and spinachi), and Changachi (dried radish). The side-dishes which showed lower preference were Alaskan pollack soup, soybean curd residue stew, cabbage Kimchi, liver Cheon, sauted liver, hairtail Chorim, radish rootNamul, and dried radish root Changachi. 3) Preferences of snacks. Fruits apple, peach, pear) were the most preferred snacks by the subjects. Male preferred ginsang tea whereas famale preferred coffee. Both bate and female subjects showed higher preference of milk and lower preference of sweets. 4) Preference of one-dish meals : No one dish meal were disliked by the subjects. Male liked Bockeum-Bab more than female, and female liked Mandukuk more than male subjects.

This experiment was designed to investigate the effects of the mixing ratio of soyprotein and casein, and the level of pectin combined with the mixture on lipid metabolism in rats. Forty-eight male weanling rats of Wistar strain weighing 58.8\;{\pm}\;1.9g$ were divided into six groups by completely randomized block design and fed 10% protein diet for four weeks. Two types of protein mixtures (casein to soyprotein mixing ratio of 1 : 3 and 2: 1)combined with 0.5% , 3%, and 5% of pectin were employed for experimental diets. The results obtained in the study are summarized as follows ; 1) Feed efficiency ratio and protein efficiency ratio were not significantly different among six groups for the whole experimental period, but those for high casein-low pectin group were significantly higher than the ones for high soy-high pectin group at 4th week of the experimental period. 2) Gross fecal dried weight and fecal lipid excretion were higher in high pectin groups of both protein combinations. Therefore, the apparent fat digestibility and absorption appeared to be significantly low in high pectin groups. 3) Pectin was effective in lowering serum lipid and cholesterol levels in high casein groups, but no effect of pectin was noted in high soyprotein groups. 4) Lipid and cholesterol contents of the liver were higher in high soy-low pectin group than the others. And no marked differences in lipid and cholesterol contents in the kidney and carcass were observed.

혐기적 조건밑에서 $FeCl_{3}$에 의해 촉진된 TBA 반응을 이용하여 혈청중 과산화물 측정을 위한 새로운미량 분석법을 설정하였다. 즉. 혈청단백침전물이 현탁된 TBA반응흔합액에 혈청 $10{\mu}l$당 $1.0{\mu}mole$의 $FeCl_{3}$를 첨가한 다음 질소기류밑에서 50분간 끊는 물에 중탕한다. 이 분석법의 반응 예민도는 현행 일반 TBA법보다 40여배나 증대되었으며 따라서 미량의 시료$(10{\sim}20{\mu}l)$로도 TBA반응생성물의 농도 측정이 비색법으로도 가능하였다. 그리고 TBA반응생성물의 butanol 추출액을 $(NH_{4})_{2}SO_{4}$염석으로 부분말수시킴으로써 예민성 및 재현성이 개선될 수 있었다. 이 분석법을 이용하여 측정한 건강인들의 혈청 TBA같은 높은 연령군일수록 증가하는 경향을 보였다.

Tannin from acorn was identified by TLC and gallic acid in the tannin was determined by HPLC. The tannin extracted with methanol-butanol was not dissolved in ethanol, methanol for HPLC and water, while the tannin extracted with acetone-ethylacetate was so pure that it could be used for HPLC-running. The gallic acid showed a Rf -value of 0.39, the digallic acid of 0.21, the trigallic acid of 0.09, and the gallotannin of 0.00 respectively. The content of gallic acid in the tannin from acorn powder was 3.04%, from acorn starch, 0.90%, and from acorn starch gels, 0.64-0.86% respectively. The effect of tannin contents on the viscosity of acorn atarch was also studied. The maximum and cooling viscosity of the starch were decreased as the contents of tannin increased.

This study was performed to investigate the placental transfer and the human fetal utilization of amino acids at term of pregnancy. The plasma levels of 23 free amino acids in both the umbilical circulation ( umbilical vein and artery ) and the uterine circulation ( uterine vein and iliac artery ) of 34 pregnant women were measured at delivery by the cesarean section. In the umbilical circulation, 9 amino acids ( alanine, lysine, valine, leucine, arginine, isoleucine, ornithine, cystine, ${\alpha}-aminobutyrate$ ) were significantly higher and 2 amino acids ( glutamate, aspartate ) were significantly lower in the umbilical vein than in the umbilical artery. In the uterine circulation, alanine, tyrosine and methionine were significantly lower in the uterine vein than in the iliac artery. Glutamate was significantly lower in the uterine vein than in the iliac artery. According to these results, the origin of fetal plasma amino acids was discussed in terms of the metabolic conversions which would occur in the Placenta and the fetal utilization of amino acids was estimated.

감자의 마쇄된 조직에서 추출한 효소액과 감자박편을 이용하여 효소적 변색에 대한 $SO_{2}$의 억제 기작을 조사하였다. $SO_{2}$는 경쟁적인 방식으로 dopachrome형성을 억제하는 것으로 나타났다. 불충분한 $SO_{2}$의 농도에서는 시간이 경과함에 따라 dopachrome의 형성이 재개시되었다. 본 실험의 결과는 $SO_{2}$가 효소적 갈변중의 중간산물과 addition compounds를 형성하여 효소적 변색을 지연시킬 수도 있다는 것을 시사하였다. 감자박편에서 dopachrome생성을 억제하기 위하여 는 마쇄된 조직에서보다 더 많은 $SO_{2}$가 요구되었다.

The present study was designed to observe the effects of soyprotein and casein with or without cholesterol on serum and liver lipids in male rats. The 6 experimental groups were as fellows ; SF ; soyprotein, cholesterol-free diet. SC ; soyprotein, 0.5% cholesterol added diet. CF ; casein, cholesterol-free diet CC ; casein,0.5% cholesterol added diet. SCF ; protein mixture of soyprotein and casein(1 : 1), cholesterol-free diet SCC ; mixed protein, 0.5% cholesterol added diet. The hypocholesterolemic and hypotriglyceridemic effects of soyprotein were observed at 3 weeks, but these effects disappeared at 6 weeks. The hypocholesterolemic effect of soyprotein was more obvious when the 0.5% cholesterol was supplemented in the diets. The serum free cholesterol level was not affected by the dietary protein source or the dietary cholesterol, therefore, the difference in serum total cholesterol among groups seems due to the difference in cholesterol esters. There was a tendency of a higher percentage of HDL in soyprotein groups compared to casein groups at 1 week, however, this tendency disappeared with time. The liver cholesterol and triglyceride contents were not differ among cholesterol-free diet groups, however, with addition of cholesterol, those of soyprotein groups were significantly lower than casein groups. The higher serum arginine/lysine ratio of soyprotein groups may offer the part of explanation of its hypocholesterolemic effect.
