摘要
欧姆加热技术利用物料的电导特性进行加热,升温迅速且均匀,营养损失少,将其应用于对流体食品的杀菌具有非常重要的意义。采用自行设计的欧姆加热杀菌试验电源装置进行单因素试验分析,初步的试验结果表明,欧姆加热杀菌方法对豆浆的总细菌具有明显的杀灭作用,而且保温时间、处理电压和处理频率对该杀菌方法的效果有显著影响。
By means of ohmic heating, food can be heated more quickly, more uniformly with less nutrition loss. It is of very great significance that the liquid food can be sterilized by this technology. The single-factor experiments and analyses were conducted using self-made ohmic heating equipment. The preliminary results show that ohmic heating has a good sterilized effect on soybean milk and temperature keeping time, voltage and frequency are three main factors of ohmic heating that affect the sterilization noticeably.
