两种提取方式下红瓜子仁油成分分析

Composition Analysis of Red Melon Seed Kernel Oil Under Two Extraction Methods

本文以红瓜子仁油为研究对象,采用两种提取方法对所获得红瓜子仁油的酸价、过氧化值、碘值、角鲨烯含量以及脂肪酸组分进行分析。结果表明,索氏提取法和水酶提取法两种提取方式下红瓜子仁油中酸价和碘值差异显著,角鲨烯含量分别为921 mg·kg^(-1)、926 mg·kg^(-1),属于植物油中角鲨烯含量较高的一类油脂。索氏提取法所获得的红瓜子仁油脂肪酸种类为10种,水酶法提取所获得的红瓜子仁油脂肪酸种类为13种,但两种提取方法下红瓜子仁油脂肪酸组成相对含量相差不大。

With the red melon seed oil as the research object,acid value,peroxide value,iodine value,squalene content and fatty acid composition of red melon seed kernel oil obtained by two extraction methods were analyzed.The results showed that there were significant differences in acid value and iodine value between the two extraction methods,and the contents of squalene were 921 mg·kg^(-1) and 926 mg·kg^(-1),which belonged to a kind of oil with high content of squalene in vegetable oil.There were 10 kinds of fatty acids in the kernel oil of red melon seeds obtained by soxhlet extraction and 13 kinds of fatty acids in red melon seed kernel oil obtained by aqueous enzyme extraction.However,the relative content of fatty acids in red melon seed kernel oil under the two extraction methods is similar.
