摘要
采用挤压膨化预处理水酶法提取调和油,并采用响应面法对酶解工艺条件进行优化。得到最佳的酶解条件为:加酶量1.84%、酶解温度50℃、酶解时间3.3h、物料质量分数17.6%、酶解pH8。经验证实验可知,在最优酶解工艺条件下,调和油提取率达到91.67%。制取的调和油满足饱和脂肪酸∶单不饱和脂肪酸∶多不饱和脂肪酸=0.46∶1∶1,n-6多不饱和脂肪酸∶n-3多不饱和脂肪酸=4∶1。
Aqueous enzymatic extraction process with extrusion pretreatment was used in this experiment to extract blending oil and the response surface method was employed to optimize the parameters in the experiment.The optimum parameters were as follows., enzyme additive amount for 1.84%, hydrolysis temperature for 50℃, hydrolysis time for 3.3h, solids-to-liquid ratio for 17.6%, pH 8.Proven experiment showed that extraction rate of blending oil could reach 91.67%.Blending oil which was extracted met the demands that the ratio of saturated fatty acids,monounsaturated fatty acids and polyunsaturated fatty acids equals to 0.46： 1：1, and that the ratio of n-6 polyunsaturated fatty acids and n-3 polyunsaturated fatty acids equals to 4：1.
