常规微生物检测方法的初步比较

Preliminary Comparison of Routine Microorganism Analysis

以常用的调味品原料及产品为样品,对3个内部和2个国家权威微生物实验室采用ISO和GB方法的检测结果进行了初步比较。结果表明:对于大肠菌群,两种方法的检测结果没有显著差异(MPN法:P=0.117;平板法:P=0.922);对于霉菌和酵母,ISO方法的检测结果明显高于GB方法(P=0.000)。

Using raw materials and products for culinary as samples,the results of ISO and GB methods by three internal and two state authoritative microbiology laboratories were compared.Preliminary results showed that,there was no significant difference between ISO method and GB method for Coliform analysis（MPN method：P=0.117;plate method：P=0.922）,Mould Yeast analysis result of ISO method was significantly higher than that of GB method（P=0.000）.
