以散装卤制鸭架为研究对象,测定其中乳酸菌在不同恒定温度下的生长。通过Gompertz方程式拟合乳酸菌生长的一级预测模型;分别运用 Belehradek 方程和二次多项式进行二级预测模型的拟合。随着温度的升高最大比生长速率(μmax)从0.73增加到2.26,延滞期(λ)从4.41减小到0.55,表明温度对乳酸菌的生长有显著影响。二次多项式拟合的二级模型的判定系数R2的值大于平方根模型;且R2的值均接近于1,初步表明模型能够预测5~25℃温度区域内卤制鸭架的乳酸菌数量变化情况。
以散裝滷製鴨架為研究對象,測定其中乳痠菌在不同恆定溫度下的生長。通過Gompertz方程式擬閤乳痠菌生長的一級預測模型;分彆運用 Belehradek 方程和二次多項式進行二級預測模型的擬閤。隨著溫度的升高最大比生長速率(μmax)從0.73增加到2.26,延滯期(λ)從4.41減小到0.55,錶明溫度對乳痠菌的生長有顯著影響。二次多項式擬閤的二級模型的判定繫數R2的值大于平方根模型;且R2的值均接近于1,初步錶明模型能夠預測5~25℃溫度區域內滷製鴨架的乳痠菌數量變化情況。

The changes of Lactobacillus of marinated duck frame in different constant temperature area were monitored. Gompertz model was used to fit one-level predict model, and two-level predict model were built respectively using Belehradek model and quadratic polynomialrelation. With the increase of temperature the maximum specific growth rate and lag phase ranged from 0.73 to 2.26 and from 4.41 to 0.55, which indicated that the growth of Lactobacillus was influenced by temperature significantly. R-square of two-level predict model built by Belehradek model was close 1 and bigger than built by quadratic polynomialrelation, which demonstrated the model developed could effectively predict the changes of Lactobacillus of marinated duck frame from 5℃ to 25℃.
