摘要: 通过不同的果胶酶对枇杷果浆的处理及其酶促反应的影响因子试验,结果表明:果胶酶处理枇杷果浆,可明显提高枇杷的出汁率及汁的透光率,利于果汁的澄清;尤以pectinex BE3-L的酶解处理效果最好,可使枇杷的出汁率提高16%、透光率提高40%以上。该酶理想的使用参数为:浓度160mg/L左右,温度35~40℃,作用时间4h。

Abstract: Different pectinase process of loquat jam and the individual factors affecting pectinase reaction were studied.The results showed that pectinase could raise juice yield and inhance transmittanty obviousely. The best prectinase was pectinexBE3-L, In contrasting to the treatment without pectinase, it could increase the juice yield up to above 16% , and transmittantyabove 40%. The optimum factors of pectinex BE3-L in loquat were 160mg/L at 35~40℃ for 4h.
