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。

摘  要:
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.
