摘要: 本文在微波加热的条件下,对豆浆饮料的微波杀菌特性进行了初步探讨,研究了加热时间、温度和菌落总数之间的关系,以及功率对豆浆中菌落总数的影响。比较在不同贮藏温度下,微波和传统水浴杀菌豆浆在不同温度贮藏过程中菌落总数的变化情况,同时测量了不同处理样品的总糖、蛋白质和折光率。结果表明:经本文方法制备的豆浆,样品体积为10ml时,其最佳微波杀菌条件为微波功率560W、加热时间22s,使豆浆温度达到75℃;在低温贮藏过程中,微波杀菌样品比传统水浴杀菌样品中的菌落总数生长缓慢,可以延长豆浆饮料的保质期;微波杀菌可以更好地保留豆浆中的营养成分。

Abstract: The experimental conditions in the microwave heating of soya milk beverages, a preliminary characteristics of microwave heating were studied, including heating time, temperature, bacteria and the relationship between them, and the effects of different microwave power on the total bacteria. At different temperatures on storage, on the process of storage of soya milk, the effect on the total bacteria between traditional hot water sterilization and microwave sterilization were compared, and measuring the total of sugars, proteins and Refractive of three samples. The results showed that 10ml soya milk the best conditions for microwave power 560W microwave heating, heating time for 22s and temperature reachs to 75℃; At low temperature storage, the total number of bacteria of microwave sterilization samples grew slower than traditional bath sterilization sample, the shelf life can be extended of soya milk drinks, microwave sterilization be in a better position to retain the nutritional content of soybean milk.
