鲜猪肉中沙门氏菌生长动力模型的建立与验证
Establishment and Validation of Salmonella Growth Prediction Model in Fresh Pork
摘要
Abstract
In order to figure out the growth of Salmonella in fresh pork,the mentioned Salmonella strains were used to make a mixture (103~104CFU/mL) and artificially contaminate the fresh pork samples. Firstly,the growth dynamics models of Salmonella at different constant temperatures were established. After the internal and external validation,the established growth prediction model was proved highly reli-able which can be used to predict the growth of Salmonella in pork. In addition, the change of storage temperature during the fresh pork bought by customers was simulated. According to the equivalent growth time theory, the growth prediction model of Salmonella in pork under the fluctuating temperature was established. After validation of the reliability, the growth of Salmonella under fluctuating temperatures exactly drew from the model. The results demonstrated that the pork should be consumed or preserved at the low temperature as soon as possible to reduce the high risk of food safety owing to the growth of Salmonella.关键词
