초록

잣나무종실(種實)의 일반성분(一般成分) 및 종실유(種實油)의 이화학적성상(理化學的性狀)을 A.O.A.C. 법(法)으로, 종실유(種實油)의 지방산조성(脂肪酸組成) 및 종자단백질(種子蛋白質)의 amino 산조성(酸組成)을 GLC법(法)에 의하여 각각(各各) 분석(分析) 측정(測定)한 성적(成績)을 다음과 같이 요약(摘要)한다. 1. 잣나무종실(種實)은 다량(多量)의 유지(油脂)(70.25%)와 단백질(蛋白質)(16.46%) 및 회분(灰分)(2.34%)을 비교적(比較的) 많이 함유(含有)하고 있다. 2. 종실유(種實油)는 옥도가(沃度價) 108,63으로서 반건성유(半乾性油)에 속(屬)하며 산가(酸價), 감화가, 굴절율(屈折率)등 이화학적(理化學的) 성질(性質)도 불포화(不飽和) 고급지방산(高級脂肪酸) 조성(組成)의 특성(特性)을 나타내고 있다. 3. 종실유(種實油)의 지방산조성(脂肪酸組成)은 oleicacid (33.6%), linoleic acid (46.7%)등 고급지방산(高級脂肪酸)의 함량(含量)이 80% 이상(以上)으로 우수(優秀)한 식용유지(食用油脂)에 속(屬)한다. 4. 16종(種)의 amino산(酸)을 분석(分析) 정량(定量)하였으며 lysine, mechionine, threonine, phenylalanine, leucine, isoleucine 및 valine등 필수(必須) amino산(酸)이 고루 비교적(比較的) 다량(多量) 함유(含有)되어 있어 좋은 단백질원(蛋白質源)이라 하겠다.

In order to analyse the composition of fatty acid in the seed oil and amino acid in the seed protein of Pinus Koraiensis seed, GLC method was applied, while the general composition of the seed and physico-chemical properties of the seed oil were also determined by A. O. A. C. method. The results obtained were summarized as follows: 1. Oil content of the seed was high as 70.25 percent, and comparatively high content of protein (16.4%) and ashes (2.34%) were observed. 2. The seed oil seemed to be belonged semi-drying oil based on the iodine absorbtion. number (108.93). The physical and chemical properties of seed oil such as acid value, saponification number and refractive index showed the composition of unsaturated high molecular fatty acid. 3. The seed oil was composed of high molecular fatty acid, 36.6 percent of oleic acid and 46.7% of linoleic acid, totaling more than 80 percent. Therefor it was good quality as an edible oil. 4. In the amino acid analysis of seed protein 16 Kinds of amino acid were determined, among them essential amino acid like lysine, methionine, threonine, phenylalanine, leucine, isoleucine and valine were abundant. From the results it was considered that the seed is good guality as a protein source.
