Abstract

The fresh mutton was infected with Enterobacteriaceae and vacuum packaged at 4℃,10℃,15℃ and20℃ for storage. The growth of Enterobacteriaceae was measured at different temperatures and analyzed with CurveExpert software to construct growth kinetics models. The results showed that growth of Enterobacteriaceae in mutton could be well described by Gompertz model in the range of temperature 4 to 20 ℃. The correlation regression of Belehradek model finely described the influence of temperature on growth. The validation was carried out by comparing actual with predicted growth of Enterobacteriaceae at 8℃ and 16 ℃. Bias and accuracy factors were 1. 0116,0. 9623and 1. 0673,1. 0715 respectively. Relative error for actual and predicted shelf-life were 6. 62%,1. 36% respectively. It was suggested the built model was effective.
