在不同的干燥条件下，考察了喷雾干燥对乙醇脱氢酶（ADH）酶活性的保留。海藻糖用于配制喷雾干燥用原料。ADH活性的保留取决于料液中ADH的浓度。添加其他蛋白质，如牛血清白蛋白和P-乳球蛋白，表现出额外的改善ADH活性的保留。干燥风的进出口温度是影响喷雾干燥酶活的另一个关键因素。喷雾干燥颗粒的表面形态随着蛋白质的加入而急剧改变。(C)2007爱思唯尔有限公司保留所有权利。
The retention of the enzymatic activity of alcohol dehydrogenase (ADH) on spray drying was examined under various drying conditions. Trehalose was used in the formulation of feed stocks for the spray drying. The retention of ADH activity was dependent on the concentration of ADH in the feed solution. The addition of other proteins, such as bovine serum albumin and P-lactoglobulin, exhibited an additional improvement of the retention of ADH activity. The inlet and outlet temperature of the drying air was another key factor for the enzyme activity on the spray drying. The surface morphology of the spray-dried particle was changed drastically with the addition of proteins. (C) 2007 Elsevier Ltd. All rights reserved.
