Inactivation kinetics of total bacteria counts in the milk exposed to dense phase carbon dioxide(DPCD) was *** inactivation of total bacteria counts was achieved at higher pressure and exposure time(p<0.05).Treatment temperature had synergistic effects with pressure and expose time on the inactivation of total bacteria counts,and lg(N/N0) significantly decreased when increasing the temperature(p<0.05).The maximum reduction was 5.082-log at 30 MPa and 50℃ for 70 *** survival curves of total bacteria counts in the milk against pressure or temperature were fitted by the Weibull model with high regression coefficients,and model parameters,a value(scale factor) and b value(shape factor) changed regularly with increasing pressure or temperature.
