以气调包装的分割鸭胸肉制品为研究对象,研究在0~20 ℃温度条件下假单胞菌的生长预测模型.结果表明:根据5 ℃温度下的挥发性盐基氮值、菌落总数、假单胞菌落数、感官评价等指标确定腐控值为6.344 2(lg(CFU/g)).Gompertz一级模型可以很准确地描述假单胞菌的生长.绘制不同温度下假单胞菌的实际值和预测值生长曲线,重合度较好.验证一级模型的预测效果,准确因子(Af)、偏差因子(Bf)均在1左右,模型拟合效果较好.用平方根模型构建了假单胞菌的二级模型,描述了最大比生长速率和延滞期与温度变化的关系.在一级模型和二级模型的基础上建立货架期预测模型,以7℃为贮藏参考温度,对货架期预测模型进行了验证....

This work reports the establishment of a predictive model describing the growth of Pseudomonas spp. in modified atmosphere packaged （MAP） duck breast meat during storage at 0-20 ℃. Results show that the spoilage limit was 6.344 2 （1g （CFU/g）） in terms of total volatile basic nitrogen （TVB-N）, total number of colonies, number of Pseudomonas spp. colonies and sensory evaluation. The Gompertz model could accurately describe the growth of Pseudomonas spp. The experimental data were well fitted to the predictive growth curves at different t...
