摘要
研究了5种最具代表性的表面活性剂对液体蛋白酶活性的影响,以及不同稳定剂及其增加量在表面活性剂溶液中对酶稳定性的贡献,为含酶液体洗涤剂中表面活性剂的筛选和今后的复配提供参考依据。结果表明,单表面活性剂对酶的稳定性依次为:AES>AEO7>AOS(已中和)>MES(已中和)>LAS;单AES或AEO7加酶只需加少量丙二醇就可通过28天的样品热储稳定性试验。
The five kinds of typical surfactants were studied on the improvement of enzyme stability in liquid detergent,and different stabilizing agents were also tested to evaluate the usefulness to this performance.The results showed that effect of each surfactant on enzyme stability is as following: AESAEO7 AOS(neutralized) MES(neutralized)LAS.Single AES or AEO7 needs only a little propylene glycol or glycerol to keep the enzyme stable in 28 days storage test.
