【摘要】 采用盐析沉淀法,配合等电点沉淀法,对猕猴桃蛋白酶提取的工艺技术进行了研究。初步选定的工艺条件为:果汁与水的比例为1∶1,食盐水浓度为22.5%~25%(W/V),pH值范围在4.0~4.8间,低温沉淀8~10 h。粗酶的平均提取率约为0.765%。更多还原

【Abstract】 This paper reports a kind of extraction technology of Actinidin by adoping the salting out and isoelectric precipitation method,in order to meet the needs of market.The optimizing extraction condition are: the ratio of material to water is 1∶1;concentration of salt water is 22.5%~25%(W/V);pH range is 4.0~4.8;time of sediment is about 8~10 h.The average extraction ratio of crude enzyme is 0.765%.更多还原
