摘要: 研究了机械压榨法、溶剂浸出法和超临界CO2萃取法等提取方法对猕猴桃籽油提取率、脂肪酸组成和理化特性的影响。结果表明:猕猴桃籽含29.20%的脂肪,机械压榨法、溶剂浸提法和超临界CO2萃取法3种方法对猕猴桃籽油的提取率分别为20.0%、26.9%和28.3%。三种方法所得猕猴桃籽油的理化常数和脂肪酸组成基本相似,但机械压榨法所得猕猴桃籽油的酸值明显偏高,油脂品质低于其它两种方法提取的猕猴桃籽油;超临界CO2萃取法更适合于提取猕猴桃籽油。

Abstract: Objective to investigate the influences of the mechanical compression, the extraction solvent and the supercritical CO2 extraction to the extraction rate, the fatty acid composition and physicochemical properties of the kiwi fruit seed oil. The result indicated that, the kiwi fruit seed fat is 29.20%, and with the mechanical compression, the extraction solvent and the supercritical CO2 extraction, the kiwi fruit seed oil extraction rate respectively is 20.0%, 26.9% and 28.3%. The components and physicochemical properties of the oil with the three methods are similar. But the acid value of the oil with the mechanical compression is higher than other two. and the quality of the oil is lower than the oil which are gotten with the other two methods. The supercritical CO2 extraction is the optimal method for the kiwi seeds oil extacting.
