Pseudomonas of pallet-packaged raw pork grown at 0, 5, 10, 15, 20 and 25°C has been studied in this paper. The modified Gompertz, Baranyi and Huang models were used for data fitting. Statistical criteria such as residual sum of squares, mean square error, Akaike's information criterion, and pseudo-R(2) were used to evaluate model performance. Results showed that there was an apparent decline in Pseudomonas growth at initial-storage phase at low temperatures. The modified Gompertz model outperformed the others at 5, 15, and 20°C, while Baranyi model was appropriate for 0 and 25°C. The Huang model was optimal at 10°C. No single model can give a consistently preferable goodness-of-fit for all growth data. The Gompertz model, with the smallest average values of RSS, AIC, MSE and the biggest pseudo-R(2) at all temperatures, is the most appropriate model to describe the growth of Pseudomonas of raw pork under pallet packaging.
本文研究了在 0、5、10、15、20 和 25°C 下生长的托盘包装生猪肉中假单胞菌的情况。使用修正的 Gompertz、Baranyi 和 Huang 模型进行数据拟合。使用残差平方和、均方误差、Akaike 信息准则和伪 R(2)等统计标准来评估模型性能。结果表明，在低温初始储存阶段，假单胞菌的生长明显下降。在 5、15 和 20°C 下，修正的 Gompertz 模型优于其他模型，而 Baranyi 模型适用于 0 和 25°C。Huang 模型在 10°C 下是最优的。没有单一模型可以始终为所有生长数据提供更好的拟合优度。在所有温度下，Gompertz 模型的 RSS、AIC、MSE 的平均值最小，伪 R(2)最大，因此是描述托盘包装生猪肉中假单胞菌生长的最合适模型。
