阪崎肠杆菌的生物学特性及其在婴幼儿配方奶粉中的预测模型
The Biological Characteristics of C.sakazakii and It's Predictive Models in Infant Formula
摘要
Abstract
The growth characteristics of Cronobacter sakazakii (C.sakazakii),the influences of temperature,NaC1 concentration and pH value on C.sakazakii in brain heart infusion broth (BHI) have been studied.This paper was aimed to establish the growth model of C.sakazakii in the reconstituted powdered infant formula (RPIF).The C.sakazakii was inoculated into RPIF and the growth data were fitted to four primary models (Baranyi model,Huang model,Gompertz model,and Three-Phase Linear) to describe the growth of C.sakazakii at the condition of 37 ℃.Results showed that the optimum growth temperature for C.sakazakii was 35~40 ℃,the optimum range of NaCl concentration for C.sakazakii was 1%~3% and the optimum range of pH value for C.sakazakii was 5~8.It also showed that the influences of temperature,NaCl concentration and pH value on C.sakazakii were significant.Huang model was particularly suitable for describing the growth of C sakazakii in RPIF than Baranyi model,Gompertz model and Three-Phase Linear model.关键词
