不同酒精度、盐度及酸碱度条件下醉泥螺中副溶血性弧菌的一级生长预测模型

通过分别控制酒精度、盐度、酸碱度三种单一变量腌制醉泥螺,测定醉泥螺中副溶血性弧菌的生长曲线,并采用SGompertz模型进行拟合,建立不同条件下的一级生长预测模型。结果表明酒精可以抑制副溶血性弧菌生长,而pH7.5和盐度3.3%的条件相对适合其生长。本文建立的醉泥螺中副溶血性弧菌在不同条件下的预测模型,可为醉泥螺安全性的预测、副溶血性弧菌的控制、工艺条件的改善提供依据。

First-order growth prediction model of Vibrio Parahaemolyticus in wine-soaked bullacta exarata with different alcohol,salinity and acidity

In this paper, the growth curve of Vibrio Parahaemolyticus in wine-soaked bullacta exarata was observed by controlling three single variables of alcohol, salinity and acidity. The SGompertz model was used to fit the model and the first-order growth prediction model under different conditions was established. The results showed that alcohol inhibited the growth of Vibrio Parahaemolyticus, while the conditions of pH 7.5 and salinity 3.3% were relatively suitable for the growth of Vibrio Parahaemolyticus. As a result, the established prediction model of Vibrio Parahaemolyticus in wine-soaked bullacta exarata under different conditions, could can provide basis for the prediction of safety of wine-soaked bullacta exarata, control of Vibrio Parahaemolyticus and improvement of technological conditions.
