摘　　要：探讨和比较了Arrhenius方程和Belehradek方程两种腐败菌生长动力学温度模型预测鱼鲜度和货架期的可靠性。结果表明,两种温度模型都能很好地预测罗非鱼中假单胞菌的生长动态和预报货架期,通过假单胞菌生长动力学模型的预测值,与罗非鱼中假单胞菌生长的实测值比较,偏差度在0.95～1.01之间,准确度在1.02～1.06之间,两种温度模型相比,Belehradek温度模型的可靠性更好。罗非鱼在3和8℃贮藏中货架期实测值与利用Arrhenius方程和Belehradek方程建立的假单胞菌生长动力学温度模型求得的预测值的比较,Arrhenius温度模型预测值和实测值的相对误差分别为11.8%和8.00%,Belehradek温度模型预测值和实测值的相对误差分别为3.47%和-7.91%,两种温度模型相比,Belehradek温度模型的结果更为理想。The reliability of growth kinetics temperature models of putrefactive bacteria developed using Arrhenius and Belehradek equations for predicting fish freshness and shelf life was investigated and compared. The results showed that the kinetics growth of Pseudomonas and shelf life for tilapia could be well predicted using the above two models. Bias and accuracy factors range from 0.95 to 1.01 and from 1.02 to 1.06, respectively, Comparing predicted val- ue using growth kinetics model of Pseudomonas with observed value of Pseudomonas growth on tilapia, Belehradek temperature equation is more reliable than another model. Comparing observed shelf life on tilapia stored at 3、8℃ with predicted values using Pseudomonas kinetics temperature model developed by Belehradek and Arrhenius equations, relative errors between observed shelf life and predicted values by Arrhenius equation are 11.8% and 8.00% ,and relative errors between observed shelf life and predicted values by Belehradek equation are 3.47 % and -7.91%. According to the above comparative results, Belehradek temperature model is better than another model.
