摘  要:
构建了恒温下的冷链运输罗非鱼微生物生长动力学模型,得出了温度变化对微生物生长状态的影响,然后对所记录温度进行了处理,并结合Baranyi模型得出了波动温度下微生物的生长动力学模型,并且用模拟试验进行了验证,决定系数为0.956,均方误差为0.165,偏差因子为0.994,准确因子为1.134。结果表明,所构建的微生物生长动力学模型能够拟合实际的冷链物流中罗非鱼微生物的变化情况。

摘  要:
The microbial growth kinetics model at constant temperature was built up.The effect of variable temperature on microbial growth state was found.Then the recorded variable temperatures were processed.Microbial growth kinetics model combined with Baranyi model under variable temperatures was obtained.A simulation experiment was also carried out to validate the accuracy of model.The determination coefficient was 0.956,the root mean square error was 0.165,the deviation factor was 0.994,and the accuracy factor was 1.134.The results showed that the model was adaptive to predict the growth of microbiology in the actual cold chain logistics.
