Abstract
The contamination situation of Listeria monocytogens in food revealed that bean products had the highest per annum risk among all the food.In this paper,the effects of temperature(4 ℃,15 ℃,25 ℃,30 ℃ and 37 ℃)on the growth of Listeria monocytogenes were investigated,and the growth data of Listeria monocytogenes at different temperatures were fitted by SGompertz and SLogistic models.And then,using the fitness (R2),accuracy factor (Af) and deviation factor (Bf) as indicators,quadratic polynomial model and square root model were selected further to fit the secondary growth models of Listeria monocytogenesin in bean products with sauce.The results showed that the SGompertz model could well describe the growth of Listeria monocytogenes at different temperature,and the quadratic polynomial model could well predict the growth of Listeria monocytogenesin in bean products with sauce.Therefore,the two models were selected as the primary and secondary growth models of Listeria monocytogenesin in bean products with sauce.This study might provide a theoretical reference for quantitative microbial risk assessment of Listeria monocytogenesin in bean products.关键词
