Establishment of growth model of Listeria monocytogenes in Fresh-cut iceberg lettuce
摘要
Abstract
This paper was designed to establish the growth model of Listeria monocytogenes in fresh-cut iceberg lettuce in different temperatures.The L.Monocytogenes was inoculated to the surface of fresh-cut iceberg lettuce and then preserved in temperature of 4 ℃,8 ℃,16 ℃,24℃,32 ℃.Gompertz model was selected as the primary model.A secondary model was created to study the effects of temperature on growth kinetics parameters of Listeria monocytogenes in the primary model.Mathematical evaluation was also conducted.The results showed that the regression of Belehradek model well described the effect of temperatures on the maximumgrowth rate and the lag phase,and correlation coefficients of determination were 0.9772,0.9847,respectively.Therefore,the model can predict the growth of L.monocytogenes in fresh-cut iceberg lettuce perfectly.关键词
