초록
수박씨를 효율적(效率的)으로 이용(利用)할 목적(目的)에서 지질(脂質) 및 단백질(蛋白質)의 특성(特性)을 검토(檢討)한 결과(結果)는 다음과 같다. 1. 수박씨의 일반(一般) 성분(成分) 중(中) 조지방(粗脂肪)과 조단백질(粗蛋白質)은 각각(各各) 40.40% 및 28.36%였다. 2. 수박씨의 지질(脂質)은 중성지질(中性脂質)이 97.35%였으며, 중성지질(中性脂質)의 성분(成分)으로는 triglyceride(50.40%) diglyceride(21.84%) 및 sterol(11.48%)이 대부분(大部分)을 차지하고 있었다. 3. 지방산(脂肪酸) 조성(組成)은 linoleic acid(55.30~67.85%) palmitic acid(12.07~28.12%) 및 oleic acid(9.06~16.40%)가 주(主) 지방산(脂肪酸)이었으며, 그밖에 stearic acid와 linolenic acid가 소량(少量)씩 함유(含有)되어 있었다. 4. 염(鹽)(0.7M
An attempt was made to find out the possibility of utilizing water-melon seed as resources of food fats and protein. The water-melon seed contained 40.40% of crude fat and 28.36% of crude protein. The lipid fraction obtained by silicic acid column chromatography was composed of about 97.35% neutral lipid, and the main components of neutral lipid by thin layer chromatography were triglyceride(50.40%), diglyceride(21.84%) and sterol(11.48%). The predominant fatty acids of total and major lipid classes were linoleic acid(55.30-67.85%), palmitic acid(12.07-28.12%) and oleic acid(9.06-16.40%), whereas stearic acid and linolenic acid were detected as small amounts. The salt soluble protein of watermelon seed was highly dispersible in 0.02M sodium phosphate buffer containing about 0.7M
