Abstract The main objective of this study was to evaluate the influence of fat content and degree of chopping of meat batters on the dose of heat which is delivered to meat during pasteurization and sterilization processes of canned meat products. Four types of canned meat were produced: coarse and finely chopped and with different meat and fat content in the formulation in each of five series. Products with lower content of fat – around 10% were concerned as “lean” while with 30% of fat as “fatty”. All types of canned meat were heated for 40 minutes in 100°C (pasteurization) and in 121°C (sterilization). During heating temperature in the core of canned meat was measured every 30 seconds. Based on that the heating dose for each type of canned meat was calculated. Independently of heat-ing and degree of chopping, higher doses were delivered to samples with lower content of fat. The degree of chopping had significant effect on pasteurization value P and sterilization value F both in “lean” and “fatty” canned products. Higher values were obtained for coarse ground that for finely chopped meat batters.
