微波灭菌技术在甘薯类食品中的研究

Research on Microwave Sterilization Method to Sweet Potato

简单地描述了微波杀菌技术的作用机理及该技术在甘薯类食品工业中和生活中的应用,利用微波加热和灭菌功能,研究微波功率、微波时间、物料薄层厚度等实验条件对细菌致死率的影响,并对食品微波杀菌中微波装置的选用、工艺确定、包装对杀菌的影响以及温度分布等问题进行了讨论。在物料薄层为3mm,微波功率为560W微波炉里灭菌30s时细菌的致死率达到了96.6%。

This article briefly describes life in the sweet potato industry and the application of the mechanism of microwave sterilization techniques and the technology,the use of microwave heating and sterilizing function,bacterial mortality impact studies microwave power,time,etc. Microwave sterilization in food selection,the process of determining microwave devices,packaging and other issues affecting the distribution and temperature of sterilization were discussed. Microwave power 560 W,microwave sterilization 30 s in a thin layer of material of 3mm,bacterial death rate reached 96. 6%.
