These results indicated a strong pro-oxidant effect of salt and an antioxidative effect of sodium nitrite, curry leaf and mint leaf extracts in pork meat. Many studies have shown that the addition of salt to meat and meat products results in an increase in the TBARS values. Torress, Pearson, Gray, and Shimokonki (1988) demonstrated that the salt was able to promote lipid oxidation in ground beef. Rhee and Zipin (2001) reported a pro-oxidant effect of salt during storage of beef and chicken. Possible reasons for salt promoted lipid oxidation are the reduction in the activity of antioxidant enzymes like catalase and glutathione peroxidases
