【摘要】 分别采用纤维素酶、果胶酶对提高胡萝卜汁中的β-胡萝卜素含量进行了研究。结果表明,先经纤维素酶处理再经果胶酶处理,胡萝卜汁中的β-胡萝卜素含量最高,与空白相比提取率约增加了14 0 %。且复合酶使用效果优于单一酶使用效果更多还原

【Abstract】 The content of β-carotene in carrot juice was studied using cellulase and pectinase. The result showed that the content of β-carotene in carrot juice treated by cellulase first and then pectinase was more than that of by the treatment of pectinase first and then cellulase. It is found that the former process yield of β-carotene is 240% of the control. Our resucts also showed that using both of the enzymes was preferable to using single enzyme.更多还原
