초록
미이용(未利用)된 폐기종실(廢棄種實)을 식량자원(食糧資源)에 이용(利用)하기 위(爲)한 연구(硏究)의 일환(一環)으로써 사과씨의 지방질(脂肪質) 및 단백질(蛋白質) 성분(成分)을 분석(分析)한 결과는 다음과 같다. 사과씨의 일반성분(一般成分) 중(中) 조지방(粗脂肪)은 25.96%, 조단백질(粗蛋白質)은 37.62%였다. 사과씨 기름에는 중성지방질(中性脂肪質)이 93.52%이나 복합지방질(複合脂肪質)은 약(約) 6.48%에 불과하였으며, 중성지방질(中性脂肪質)의 성분(成分)으로써는 트리-글리세리드가 92.17%, 스테롤 에스터, 스테롤, 디글리세리드 및 유리(遊離) 지방산(脂肪酸)은 각각(各各) 3.53%, 2.28%, 1.44% 및 0.56%였다. 지방산(脂肪酸) 조성(組成)은 총지방질(總脂肪質)과 중성지방질(中性脂肪質)에서 리놀레산
The apple seed contained 25.96% of crude fat and 37.62% of crude protein. The lipid fractions obtained by cilicic column chromatography were mainly composed of about 93.52% neutral lipid, whereas compound lipid was only 6.48% level. Among the neutral lipid separated by thin layer chromatography, triglyceride was 92.17%, sterol ester, sterol, diglyceride and free fatty acid were 3.53, 2.25, 1.44 and 0.56, respectively. The predominent fatty acids of total and neutral lipids were linoleic acid (59.79-69.37%) and oleic acid (20.04-29.82%), but those of glycolipid and phojspholipid were linoleic acid (29.20-36.04%). The major fatty acids of triglyceride separated from neutral lipid were oleic acid (44.31%), linoleic acid (36.66%) and palmitic acid (12.48%). The salt soluble protein of apple seed was highly dispersible in 0.02M sodium phosphate buffer containing about 1.0M
