The Development of Predictive Growth Models for Total Viable Cells and Escherichia coli on Chicken Breast as a Function of Temperature

摘要: Abstract The aim of this research was to estimate the effect temperature and develop predictive models for growth totalviable cells (TVC) Escherichia coli (EC) on chicken breast under aerobic various conditions. pri-mary were determined by Baranyi model. secondary specific rate (SGR) lag time(LT), as a function storage temperature, developed polynomial initial contamination level ofchicken breasts around 4.3 Log CFU/g TVC 1.0 E. . During 216 h storage, SGR TVCshowed 0.05, 0.15, 0.54 CFU/g/h at 5, 15, 25 o C. Also, tendency EC similar those TVC.As increased, values microorganisms increased dramatically LTdecreased inversely. predicted with experimental data evaluated B f , A RMSE R 2 Thesevalues indicated that these reliable express breasts. Thetemperature changes distribution showcase in markets might affect spoilage mainly.
