The three levels of predictive models and their application in shelf life prediction were summarized and the future trend of predictive microbiology was prospected.
Through mathematical modeling,predictive microbiology can qualitatively analyze the growth and survival of pathogens and spoilage microorganisms existed in foods under various conditions.Therefore,it can reasonably predict the shelf life of foods.The three levels of predictive models and their application in shelf life prediction were summarized.The future trend of predictive microbiology was prospected as well.
