Abstract: | Objective] To discuss the determination method of total bacterial count in the fast frozen fruits and vegetables.Method] The total number of bacteria was detected by PertrifilmTM strip for rapid detection,and the effect of different temperature on the bacterial count was studied.Result] 30 ℃ culture was more effective than 36 ℃ culture in the national standards to detect the total bacterial count in the samples,indicating that it is necessary to improve the bacterial determination method.Only with a more accurate determination method,the quality of fast frozen products can be effectively controlled.Conclusion] The improved determination method can objectively reflect the health and quality of products,providing a basis for their hygienical evaluation. |
