Abstract:

The study aimed to investigate the rapid detection method of thermotolerant coliforms in cosmetics. The 3M Petrifilm TM coliform count plate method and Loop-mediated isothermal amplification(LAMP)technique were used to rapidly detect thermotolerant coliform bacteria in artificially contaminated cosmetics, and compared with the traditional flat plate detection method. The results show that the 3M Petrifilm TM coliform test method and the traditional detection method have no statistical difference, and the operation procedure is simple. The LAMP technique has strong specificity, sensitivity of 2.03 μg/L, and is time-consuming. 3M Petrifilm TM coliform count plate method and LAMP technique can be used for rapid detection of thermotolerant coliforms in cosmetics.

Key words: cosmetics, coliforms, count plate, Loop-mediated isothermal amplification technique
