摘  要：
果汁加工过程中,为延长超滤有效运行时间,以富士苹果、秦冠苹果为材料,研究了酶解工序中使用复合纤维素酶对超滤通量和有效运行时间的影响,并进行了产业化应用.结果表明:添加复合纤维素酶,降低了酶解罐和超滤潴留罐中不溶物的含量,提高了超滤通量,延长了超滤运行时间,且对浓缩苹果汁的可溶性固形物含量、色值、浊度等品质指标没有影响;复合纤维素酶适宜的添加量为30~100 mL/t;经过产业化应用发现,采用该技术,加工成熟度较大的苹果,超滤运行时间从13~16 h延长到20~24 h,超滤每周期有效运行时间提高45%以上,且平均通量比正常工艺提高10%以上.

摘  要：
In order to reduce the content of insoluble solid(pulp fiber) in juice in the clarification tank and extend the effective operation time of ultrafiltration during the producing of juice, this paper takes "Fuji" apple and "Qinguan" apple as raw materials to research the influence of cellulase in juice processing on the ultrafiltration flux and effective operation time and carries out industrialization experiments. The experiment results show that: adding compound cellulase to the clarification tank and the ultrafiltration retention tank does not increase the amount of cellobiose in the final decomposition product, reduces the content of insoluble solid(pulp fiber) in clarification tank and ultrafiltration retention tank, increases the ultrafiltration flux, extends the ultrafiltration operation time and reduces the the frequency of ultrafiltration for sugar extraction and cleaning in the existing apple juice processing technology due to the high content of insoluble solid(pulp fiber) in the ultrafiltration retention tank. And finally to realize the effect of reducing consumption and emission in juice processing, reducing production cost and improving production efficiency.
