摘 要 : 采用响应面优化尿素包合法富集黑加仑籽油中 γ-亚麻酸的最佳工艺。在单因素试验基础上,选择包合温度、
尿素/混合脂肪酸配比、95 % 乙醇/尿素配比(mL/g )、包合时间为考察因素,进行四因素三水平的Box-Behnken 中心组合
设计,采用响应面法分析 4 个因素对籽油中 γ-亚麻酸含量的影响。结果表明,尿素包合法富集黑加仑籽油中 γ-亚麻酸
的最佳工艺为包合温度-20 ℃、尿素/混合脂肪酸配比 3.5 ∶ 1、95 % 乙醇/尿素配比 2.5 ∶ 1(mL/g )、包合时间21 h ,在此条件
下,包合后籽油中 γ-亚麻酸含量平均值为 24.27 %。

Abstract : The present study aimed to optimize enrichment of γ-linolenic acid from blackcurrant seeds oil using
urea inclusion method and response surface methodology (RSM ) combined with a 4-variable , 3- level Box-
Behnken central composite design ( ) ,
CCD on the basis of single factor experiments. Inclusion temperature ratio
of urea-to-fatty acid ,ratio of 95 % ethanol-to-urea (mL/g )and inclusion time were studied. Results showed that
the optimized enrichment conditions are inclusion temperature -20 ℃ , urea-to-fatty acids
