摘要
通过气相色谱 GC 分析了华山松籽油的主要脂肪酸组成.结果表明:华山松籽含油率为56.5%,其中主要含有亚油酸63%,油酸26%,棕榈酸5%,硬脂酸2%,花生酸1%,芥酸1%,不饱和脂肪酸总量达90%.抗氧化研究采用Schaal烘箱法63±1℃,即在松籽油中加入几种不同的抗氧化剂进行加速氧化.结果表明:抗氧化剂二丁基对甲苯酚、没食子酸丙酯、特丁基对苯二酚对松籽油有明显的抗氧化作用,其中特丁基对苯二酚效果较好,柠檬酸对其具有协同增效作用,添加50mg/kg柠檬酸,抗氧化效果显著.VE无显著作用.
The composition of fatty acids in the seed kernel oil of Pinus armandi was analysed by GC.The results showed that the oil contents of seed kernel of Pinus armandi was 56.5%.The oil consisted mainly of linoleic acid 63%,oleic acid 26%,palmitic acid 5%,stearic acid 2%,arehidic acid 1%,erucic acid 1%.The total amount of the unsaturated fatty acid was 90%.Antioxidation research was made in oven 63±1℃.Several antioxidants were added to seed kernel oil of Pinus armandi.The results showed butylated hydroxytolene (BHT),propyl gallate (PG) and tertiary butylhydroquinonoe (TBHQ) were effective antioxidant.TBHQ was more effective than any others.Synergist tests showed that 50 mg/kg lemon acid can improve antioxidation of TBHQ.VE had no significant antioxidation.
