摘　　要：为了更好评估蛋白酶在中国自动洗碗剂中的应用性能,比较不同洗碗剂配方在蛋白类污渍上的去污能力,研究开发了一种与中国消费者相关的蒸蛋污渍和洗涤测试方法。在实验室条件下测试得到了该污渍对不同计量蛋白酶的响应曲线,并采用该方法测试了市售洗碗剂产品的去污力。结果表明,不含蛋白酶的洗碗剂对该污渍的去除率低于10%,蛋白酶添加量为0~2.0%,污渍去除率随着蛋白酶计量的增加而提高。该污渍对蛋白酶有很好的计量响应,能有效区分市售洗碗剂产品清洁性能,可用于洗碗剂配方的开发、筛选和去污力评价。In order to better evaluate the cleaning performance of protease in Chinese automatic dishwashing(ADW)detergents and comparing the washing performance of different ADW detergent formulations on protein stains,a test method was developed.Steamed egg stain,which was a Chinese-consumer-relevant soil,was used as monitor.The response curves of the stain to different amounts of protease were measured under laboratory conditions,and the stain removal ability of commercially available ADW detergents was tested with this method.The results showed that the soil removal rate of the ADW detergent without protease was less than 10%,and the soil removal rate increased with the increase of protease dosage in the protease range of 0~2.0%.Steamed egg stain had a good response to protease,and it could effectively distinguish the cleaning performance of commercial ADW detergents.The test method could be used in the development,screening and evaluation of ADW detergent formulations.
