摘要
目的:建立小肠结肠炎耶尔森菌在猪肉中的存活/失活预测模型,并提出其控制措施。方法:用浓度梯度稀释法计细菌总量,按对数法作出不同条件下小肠结肠炎耶尔森菌的生长曲线。采用预测微生物学的基本方法和程序,并用CurveExpert1.38软件作为辅助工具,对试验数据进行拟合。结果:50℃、-18℃及速冻条件下该菌的初始菌数与时间为T时的菌数之比关于时间T的存活/失活预测模型符合Linear关系式,分别为Log(No/Nt)=1.0477287+0.1705726T,Log(No/Nt)=0.091057233+0.036013901T,LogNt=-0.0651058+0.97683871LogNo。结论:实验表明,本菌对高温非常敏感,在冷冻,速冻过程中仍能存活。
To establish inactivation/survival prediction model of Yersinia enterocolitica in pork and present some measures to control the Yersinia enterocolitica.Methods:Inventory of bacteria by the concentration gradient dilution was counted. The survival and inactivation curve of Yersinia enterocolitica by logarithm was drawn. The basic method and procedure of predictive microbiology was applied. And CurveExpert1.38 software as a complementary tool was used to fit to the experimental date.Result:At 50℃,-18℃ and dur...
