摘要

Abstract

The effect of different microwave heating conditions on inactivation of Salmonella,Escherichia coli and Staphylococcus aureus were investigated.The feasibility of Weibull model on description of the inactivation process was studied and Weibull model was also used to predict the 5-log reduction time for the three target bacterium.Results indicated that Weibull model showed ideal goodness of fit.The estimated 5-log reduction time from the Weibull model was confirmed to be closed to the observed values.
