摘要
研究了酶解-醇提从长枣中提取长枣色素的工艺过程及工艺条件,通过单因素和正交试验得到的最佳工艺参数:料水比为1∶20,粉碎度60目,酶加量为1%,酶解温度50℃,酶解时间40 min,酶解pH 6,乙醇浸提的体积比为1∶3,此条件下长枣色素的得率为9.85%。
This paper studied the technological processing and conditions of extraction of long jujube pigment from long jujube with methods of enzymolysis-alcohol extraction, by single-factor experiment and orthogonal experiment the optimal technological parameters is found as follows, material-water ratio 1 ： 20, comminution degree 60 meshs, enzyme dosage 1%, enzymolysis temperature 50 ℃, enzymolysis time 40 min, enzymolysis pH 6, ethanol extraction volume ratio 1 ： 3, under these conditions the extraction rate of long jujube pigment is 9.85%.
