摘要
对金堂县6个引进油橄榄品种的含油率、初榨橄榄油的酸值、过氧化值、α-生育酚含量、豆甾醇含量、β-谷甾醇含量、脂肪酸组成进行测定,并利用主成分分析对其品质进行了综合评价。结果表明,6个油橄榄品种的果实含油率为11.66%～15.55%,品种间存在一定差异;初榨橄榄油的酸值和过氧化值均较低;克罗莱卡的α-生育酚含量最高(149.07 mg/kg),小苹果的β-谷甾醇含量最高(851.25 mg/kg),莱星、豆果和哥朗米扎的豆甾醇含量明显高于其余3个品种;初榨橄榄油主要由11种脂肪酸组成,不饱和脂肪酸含量为75.52%～83.74%,饱和脂肪酸含量为14.61%～19.06%。综合评价表明,莱星品质最好,其次是哥朗米扎和克罗莱卡。
The oil content,acid value,peroxide value,contents of α-tocopherpl,stigmasterol and β-sitosterol and fatty acid compositions of virgin olive oils from 6 introduced varieties of Olea europaea L. in Jintang County were analyzed,and the quality was evaluated comprehensively by principal component analysis(PCA).The results showed that the oil content of fresh fruits from 6 introduced varieties were 11.66%-15.55%.The acid value and peroxide value of virgin olive oil were low.The content of α-tocopherpl of Koreniki was the highest(149.07 mg/kg),and the content of β-sit-osterol of Manzanilla was the highest(851.25 mg/kg).The contents of stigmasterol of Leccino,Arbequina and Goramitza were obvious higher than that of the other 3 varieties.The virgin olive oils were made up of 11 fatty acids,and the contents of unsaturated fatty acids and saturated fatty acids were 75.52%-83.74% and 14.61%-19.06%,respectively.Synthetical evaluation indicated that Leccino had the best quality among the 6 varieties,followed by Goramitza and Koreniki.
