摘　　要：为探索亚麻籽最优脱胶工艺参数,采用果胶酶对亚麻籽进行脱胶,以亚麻籽脱胶率为衡量指标。在单因素试验的基础上,通过正交分析得出在不同的工艺条件下,果胶酶对亚麻籽进行脱胶效果的影响。结果表明:酶解温度34℃、酶解时间3h、加酶量1 500U·g^(-1)、pH为7时,脱胶率最高,为93.3%。In order to explore the optimal degumming process parameters of flaxseed,pectinase was used to degummy flax seed,and the degumming rate of flaxseed was a measure.On the basis of single factor experiment,orthogonal analysis in different process conditions,effect of pectinase on degumming of flax seed was analyzed.The results showed that the hydrolysis temperature of 34 ℃,the hydrolysis time was 3 h,the amount of enzyme was 1 500 U·g^(-1),the pH was 7,the highest rate of degumming,the degumming rate was 93.3%.
