| 摘 要： | 本文研究了利用LS1型科研型超滤机制备生姜蛋白酶 ,结果证明 :操作压力为0 06Mpa时 ,酶活力和膜通量最好 ,浓缩度为80%,生姜蛋白酶得率为2 3%;膜通量随操作温度、姜汁流速的提高而增加 ,随姜汁浓度、操作时间的增加而降低 ;超滤法比单宁法、乙醇法提取的生姜蛋白酶的酶活力和得率高 ,更具有工业化生产价值。

| Abstract: | The zingibain were extracted from ginger juice by ultra filtration (UF) with domestic hollow fibers. It was shown that the permeate flux increased with increasing operation temperature within certain limits and flow velocity of ginger juice, and decreased with increasing concentration of ginger juice and operation time, and when operation pressure was 0.04Mpa～0.06Mpa, the protease showed the highest proteolytic activity and the maximum permeate flux. The output by UF got 2.3%. The zingibain by UF had the higher proteolytic activity and output and industrial production value than the zingibain by alcohol and tannin. |
