| 摘 要： | 采用单一果胶酶处理草莓,通过正交试验优化酶解工艺,当加酶量0.04%、pH 4.0、酶解温度40℃、酶解时间60min时,草莓出汁率最高,为91.21%,比对照组(直接挤压榨汁)提高29.97%。采用复合酶(果胶酶、纤维素酶、木聚糖酶、β-葡聚糖酶)处理,草莓出汁率比对照组(直接挤压榨汁)提高30.94%,比单一果胶酶处理提高0.97%,复合酶解最佳条件为:果胶酶添加量0.04%、纤维素酶添加量0.03%、木聚糖酶添加量0.02%、β-葡聚糖酶添加量0.04%、酶解温度40℃p、H 4.0、酶解时间60 min。

| Abstract: | The strawberries were treated with pectinase alone,and their enzymolysis technology was optimized through the orthogonal experiments,when the amount of the added pectinase was 0.04%,pH-value was 4.0,enzymolysis temperature was at 40 ℃,and enzymolysis time was 60 min,the highest juice extraction rate（91.21%） was gotten,which was 29.97% higher than that of the control group（directly squeezing the juice）.When the strawberries were treated with compound enzymes（pectinase,cellulose,xylanase and β-glucanase）,the juice extraction rate was 30.94% higher than that of the control group,and 0.97% higher than that of alone pectinase treatment.The optimum conditions of complex enzymolysis were pectinase 0.04%,cellulose 0.03%,xylanase 0.02%,β-glucanase 0.04%,enzymolysis temperature 40 ℃,pH-value 4.0 and enzymolysis time 60 min. |
