摘要
对菜籽酶法直接浸出工艺进行了研究。分析了影响浸出工艺条件的因素 ,通过正交实验和极差分析 ,得出最佳的工艺参数。研究结果表明 ,菜籽坯片水分在 12 %、浸出时间 14 0min、蛋白酶浓度为 1%、酶处理时间为 12h、浸出温度为 5 0℃和纤维素酶浓度为 1%、酶处理时间为 2 4h、浸出温度为 5 0℃时 ,油脂提取率最高。
Enzyme use in rapeseed direct extraction technology was studied.In order to get optimal extraction technology parameters,orthogonal experiments were undertaken.The results show that the oil yield efficiency is high at the water content of rapeseed flake 12%,the concentration of protein enzyme 1%,enzyme use in processing for 12 h and extraction temperature 50℃.The high oil yield efficiency can be got when the rapeseed flake with 12% water content is treated by 1% cellulose enzyme for 24 h,and then extracted 140 min at 50℃.Moreover, at the same processing situation,the effect of cellulose enzyme is superior to protein enzyme.
