超声波灭菌试验初探

采用超声波发生仪作为灭菌设备，以酱油作为灭菌对象，用超声波对酱油做了不同灭菌时间的试验。结果表明：超声波对液体食品灭菌是有效的，当累计灭菌时间达到４ｍｉｎ时，所处理的酱油样品微生物总数指标达到了合格。

A preliminary inquiring into sterilizing experiment by Ultrasoni wave

In this article ,with ultrasonic wave generator as sterilizing device and soy sauce as testing material experiments on soy sauce treated by ultrasonic wave with different sterilizing time duration have been made.The experimental results showed that ultrasonic wave is effective in sterilizing of liquid food. When the accumulative time of sterilizing reaches 4 min ,the sum total index of the microorganism in the soy sauce sample being treated with is up to standard.
