摘要: 为了最大限度提高脂肪酶催化亚麻油的水解率,研究影响亚麻油水解率的pH值、反应时间、乳化剂用量、加酶量、油水比等因素。通过分析试验数据,利用数学软件Matlab进行拟合,建立预测模型,再进行实验验证,发现在温度33℃、pH5.9、时间29h、脂肪酶用量13600U/g、油:水1:2(V/V)的工艺条件下,水解率可以达到62.6%,为后续的尿素包合纯化打下良好的基础。

Abstract: To maximize the degree of lipase-catalyzed hydrolysis of linseed oil, the reaction conditions pH, time, emulsifier amount, enzyme amount and oil-to-water ratio were investigated. A predictive model was established through data fitting with the mathematical software Matlab. A degree of hydrolysis of 62.6% was achieved after 29 h of hydrolysis at pH 5.9, 33 ℃, an oil-to-water ratio of 1:2 (V/V), and an enzyme amount of 13600 U/g.

Key words: linseed oil, degree of hydrolysis, lipase, mixed fatty acids
