a good medium for the growth of the most hazardous
spore forming anaerobe, Clostridium botulinum. The assurance
of a thermally processed food is based on establishing
the sterility value, which is determined by using the most
heat resistance organism, C.botulinum in low acid foods. As
this organism is highly toxic, Clostridium.sporogenes PA
3679 that is physiologically similar to C.botulinum is used
for thermal resistant studies. The advantages of using
C.sporgenes PA 3679 for such studies in foods are it’s non
toxigenic characteristics and thermal process behavior i.e a 5
log reduction(5D) of this organism is equivalent to a 12 log
reduct ion (12 D) of C.botulinum (NCA 1968). Therefore it
has a built in safety factor in standardization of thermal
process schedules in food processing. The main objective
of this study was to calculate thermal process schedules the
for buffalo meat blocks in retort pouches by determining the
