摘要:

采用水酶法提取玉米胚芽油并对工艺进行优化。通过单因素试验和正交试验,确定水酶法提取的最佳工艺条件:液料比5:1(mL/g)、复合酶用量2.5%、酶解时间7h、pH6.0,复合酶种类为纤维素酶和α- 淀粉酶,添加质量比为4:3。在此条件下,玉米胚芽油提取率为89%。气相色谱对玉米胚芽油进行分析结果表明:油酸、亚油酸含量分别为43.46% 及40.22%。

Abstract:

Water-enzymolysis method was used to extract corn germ oil. The optimal extraction processing parameters were explored by single-factor and orthogonal experiments to be material-liquid ratio of 1:5 (g/mL), compound enzyme addition amount of 2.5%, enzymatic hydrolysis time of 7 h and hydrolysis pH of 6.0. The compound enzyme was composed of cellulase and α-amylase with a mass ratio of 4:3. Under the optimal extraction processing conditions, the extraction rate of corn germ oil was up to 89%. Gas chromatography analysis indicated that the contents of oleic acid and linoleic acid in corn germ oil were 43.46% and 40.22%, respectively.

Key words: corn germ oil, water-enzymolysis, corn germ oil, gas chromatography
