摘要:

以鲐鱼为研究对象,进行恒温下细菌总数的计数并建立基于Baranyi模型的微生物生长动力学模型。对Baranyi模型进行改进,构建波动温度下的微生物生长动力学模型,并运用模拟实验对模型进行验证,验证结果是偏差因子为1.23,准确因子为1.12,表明所构建的微生物生长动力学模型能够很好的拟合波动温度下鲐鱼中微生物的变化情况。

Abstract:

The aerobic plate counts of mackerel meat during cold storage at fixed temperatures were enumerated and the
acquired data were used to establish a microbial growth kinetics model based on Baranyi model. The Baranyi model was
modified to develop a microbial growth kinetics model for cold storage at changing temperatures and the new model was
validated by simulation experiments with a bias factor of 1.23 and an accuracy factor of 1.12. These results showed that the
microbial growth kinetics model could fit the change of microbes in mackerel at fluctuating temperatures.

Key words: mackerel, growth kinetic model, fluctuating temperature
