4. Final considerations
Pasteurized meat and liquid egg food products must be stored
under refrigerated conditions, to avoid growth of surviving sporeformers.
Regarding liquid egg products, an alternate process must be
devised since too high temperatures (≥60 °C) coagulate the egg,
negatively affecting the texture/quality.
Within high moisture foods, larger D-values were observed with
a cocktail of 6 Salmonella including Senftenberg serovar, in ready-toeat
chicken fried beef patties: D55ºC=68 min, D60ºC=16 min, D65ºC=
2 min, D70ºC=0.22 min, z=6.0 °C.
Some authors found the use of alternative non-linear models more
effective for predicting Salmonella survivors in pasteurized foods.
The conclusions and recommendations for thermal pasteurizations
can be extended to non-thermal pasteurization processes, it being necessary
to determine microbial D- and z-values, or non-thermal resistance
parameters of other models, with respect to the new technologies
