摘　　要：为解决豆浆通电加热过程中的极板污染问题,该文研究了在豆浆的连续通电加热过程中,电源频率对于电源极板污染的影响。试验表明,相比于100Hz的低频交流电,频率超过1000Hz的高频交流电能有效抑制电源极板污染。研究结果对于通电加热在豆浆加工的应用提供了依据,并对富含蛋白质液体食品连续通电加热中极板污染的研究提供参考。In order to solve the problem of electrode pollution, the effect of power supply frequency on electrode pollution during continuous ohmic heating of soybean milk was investigated. The experiments showed that the high frequency （〉1000 Hz） alternative power supply can effectively reduce the pollution of the electrode as compared to 100 Hz AC frequency. This research can provide a theoretical reference for ohmic heating application in soybean milk processing, as well as other research on ohmic heating electrode pollution of protein-rich liquid food.
