大肠菌群测试片在化妆品微生物检测中的应用

Application of Petrifilm Colony Count Plate in Microbial Detection for Cosmetics

目的:研究评价大肠菌群测试片(Petrifilm)在化妆品微生物检测中的应用。方法:通过对14批化妆品人工添加3种常见试验菌,采用《化妆品卫生规范》和Petrifilm菌落总数测试方法进行比对。结果:用两种方法检测结果差异不明显,经t检验,P>0.05,统计学数据表明两种方法相比差异无统计学意义。结论:Petrifilm菌落总数测试片法因其轻便、快速、简易的优势在化妆品的微生物检测中具有重要意义。

Objective： To study the application of petrifilm colony count plate in the microbial detection for cosmetics. Methods：Three common microbials in 14 batches of cosmetics were respectively detected by the method described in hygienic standard for cosmetics and petrifilm colony count plate,and the results were compared. Results： The results shown by the two methods had no statistically significant difference（ P 0. 05）. Conclusion： Petrifilm colony count plate with light weight,fast and easy operation exhibits significance in the microbial detection for cosmetics.
