摘要
使用真空泵将待测乳制品抽滤到细菌滤膜上,把细菌滤膜固定在玻碳电极上,在p H值为7.0磷酸盐缓冲液中,控制电解池内温度为25℃,以饱和Ag/Ag Cl电极作为参比电极,2 min内进行伏安法快速测定,可以检测乳制品中的细菌总数。该方法与平板计数法的检测结果一致。
Dairy products were filtered to bacterial membrane using a vacuum pump. Then bacterial membrane was pasted on the face of glassy carbon electrode. The modified electrode was placed in p H7.0 phosphate buffer with saturated Ag/Ag Cl electrode as the reference electrode when the cell temperature is 25 degree centigrade. Bacterial contamination in dairy products was detected rapidly by voltammetery in 2minutes. The test result is consistent with the plate count method.
