Abstract

In order to increase malt enzymic activity, cellulases from the fungus Geotrichum candidum were used. Malt milk was processed for 1--3 hr at 40 degrees C and pH 6.0--6.5 by the fungal preparation or culture fluid filtrate used in such quantities in which there were 0.5 to 9.0 units of cellulase activity per g malt. During the process enzymic activities of malt increased significantly: dextrinating activity--by 73%, amylolytic activity--by 60--100%, saccharifying activity--by 3.4 times, and proteolytic activity--by 2 times.

摘要

为了提高麦芽酶活性,使用了来自白地霉的纤维素酶。将麦芽乳在40℃和pH 6.0 - 6.5下用真菌制剂或培养液滤液处理1 - 3小时,所用的量为每克麦芽中有0.5至9.0单位的纤维素酶活性。在此过程中,麦芽的酶活性显著增加:糊精化活性增加73%,淀粉分解活性增加60 - 100%,糖化活性增加3.4倍,蛋白水解活性增加2倍。
