【摘要】 以新疆巴旦杏Amygdaluscommunis28个品种为材料,采用超临界CO2萃取法萃取其种仁油脂,并用气相色谱法测得其脂肪酸的含量及组分。结果表明,巴旦杏种仁油脂含量高(平均为54 68g·100g-1),油脂以不饱和脂肪酸为主要成分,平均占脂肪酸总量的92 3%,不饱和脂肪酸中,以单不饱和脂肪酸———油酸含量最高(63 72%～75 89%),其次是亚油酸、棕榈油酸和亚麻酸,且亚油酸和亚麻酸含量适当,既能满足人体保健所需,又具较好的耐贮特性。从营养保健的观念出发,巴旦杏仁油是一种亟待产业化开发的高档新型食用植物油。更多还原

【Abstract】 The methods of super-critical CO 2 extraction was used to get the oil sample of 28 almond varieties from Xinjiang.The contents and composition of fatty acids were tested by gas chromatography.The results indicated that almond averagely contains 54.68g·100g^-1 fatty oil, among which unsaturated acid is the major component,accounted for 92.3%. Oleic acid, an unsaturated mono fatty acid, constitutes 63.72%-75.89% of unsaturated fatty oil. Linoleic acid, palmoil acid and linolenic acid are in the next place. There were suitable contents between linoleic acid and linolenic acid. So in the view of nutriology, almond oil is a new and higher grade vegetable oil to be developed and used.更多还原
