Abstract

This study determined the effect of acid, alkaline, chlorine, and ethanol stresses on the thermal inactivation of Enterobacter sakazakii in infant milk formula. Unstressed or stressed cells were mixed with reconstituted powdered infant milk formula (PIMF) at temperatures between 52 and 58 degrees C for various time periods or mixed with PIMF prior to reconstitution with hot water between 50 and 100 degrees C. D- and z-values were determined using liner regression analysis. In general, detergent and sanitizer stresses decreased the thermal resistance of E. sakazakii in infant milk formula. The results of this study may be of use to regulatory agencies, manufacturers, and infant caregivers to design heating processes to eliminate E. sakazakii.

摘要

本研究测定了酸、碱、氯和乙醇胁迫对婴儿配方奶粉中阪崎肠杆菌热失活的影响。将未受胁迫或受胁迫的细胞与复原的婴儿配方奶粉粉（PIMF）在52至58摄氏度的温度下混合不同时间段，或在与50至100摄氏度的热水复原之前与PIMF混合。使用线性回归分析确定D值和z值。一般来说，洗涤剂和消毒剂胁迫会降低婴儿配方奶粉中阪崎肠杆菌的热抗性。本研究结果可能对监管机构、制造商和婴儿护理人员设计消除阪崎肠杆菌的加热工艺有用。
