ABSTRACT
The combination effect of high hydrostatic pressure and moderate heat on the inactivation kinetics of Bacillus coagulans spore in phosphate buffer and UHT(Ultra High Temperature)whole milk was investigated.The pressure come-up time and corresponding log-reduction of spore inactivation were considered during pressure-thermal treatment.Bacillus coagulans spore had a much higher resistance to pressure in UHT whole milk than in phosphate buffer.Survival data were modeled using the linear,Weibull and log-logistic models to obtain relevant kinetic parameters.The tailing phenomenon occurred in all survival curves,indicating the linear model was not adequate for describing these curves.The log-logistic model produced best fits to survival curves,following by Weibull model.
