Abstract: Psychrotrophic bacteria grow and reproduce rapidly in raw milk under cold conditions while producing some proteases and lipases which may affect the quality of both raw and processed milk. On the basis of the data on raw milk under different regional, seasonal and management conditions collected in China and abroad, this article presents a comparative analysis of the composition and quantity of psychrotrophic bacteria and of the prospects for the application of various technologies for rapid detection of psychrotrophic bacteria in raw milk with focus on the detection time, the limit of detection and the correlation coefficient of the calibration curve as well as the advantages and disadvantages. Next, it summarizes the current status of the control of psychrotrophic bacteria in practice. We believe that the quality and safety control of dairy products will be guaranteed by the combined use of rapid detection technologies and microbial traceability technologies.

Key words: raw milk; psychrophilic bacteria; rapid detection; control technologies
