摘要
采用尿素包合法富集湘西月见草籽油中的γ-亚麻酸,通过对包合时间、脲合用料比和包合温度等因素的正交试验研究,得到最佳条件为脲合用料比(脂肪酸:尿素:乙醇,m/m/V)1:3:8、包合温度-20℃、包合时间12h,此条件可使其中γ-亚麻酸的含量由10%提高到51.9%以上。
In this study,enrichment ofγ-linolenic acid in evening primrose oil was conducted through urea inclusion method.The condition for inclusion was investigated to optimize inclusion time,urea and material ratio,and inclusion temperature through orthogonal tests.The optimal condition for inclusion was 1：3：8 of fatty acid,urea and ethanol（m/m/V）,-20 ℃ of inclusion temperature,and 12 h of inclusion time.The content ofγ-linolenic acid was significantly improved through urea inclusion and reached 51.9% under this optimal inclusion condition from 10%.
