Abstract:
Dumplings fillers were inoculated with Staphylococcus aureus, and then were placed at 4, 10, 15, 20 and 25℃ for storage.The growth of Staphylococcus aureus at different temperatures was described by Gompertz model.The relationship between temperature and maximum specific growth rate (μ max) , lag phase (Lag) of Staphylococcus aureus described by Belehradek model.The results proved the built model could describe the growth of Staphylococcus aureus effectively, and the kinetic growth parameters expressed a good linearity by Belehradek model.The built Gompertz model was tested by the growth of Staphylococcus aureus at 13℃ and 18℃, and proved the growth kinetics model was effectively.
