| Abstract: | TBA-reactive material was produced in pieces of bovine semitendinosus muscle and adipose tissue during storage at 2° 2°C and ?10° 2°C. The process was faster in muscle than in adipose tissue and the total content, higher at 2°C than at ?10°C. The effect of sprying butylated hydroxytoluene and a citric acid-EDTA-ascorbic acid mixture on the production of malonaldehyde was studied. Declines in both saturated and unsaturated fatty acid proportions of the polar lipids without increases in the content of free fatty acids suggests that enzymes involved in lipid catabolism remain active at low temperatures. Whereas lipid breakdown was unaffected, malonaldehyde production was inhibited by sprying antioxidants in early stages of the slaughtering process. |
