This study was conducted to investigate the effects of antioxidants on lipid oxidation in uncooked ground pork which was treated with ${\alpha}-tocopherol$, GFSE (grapefruit seed extract), carnosine and rosemary, respectively. The ground pork samples were uncooked and cooked during 10 days of storage at $4{\pm}1^{\circ}C$, respectively. The lipid oxidation and fatty acids composition were analyzed for over a periods of storage day. From the results mentioned above, antioxidative activity on lipid oxidation of uncooked ground pork appeared to be in order of carnosine > rosemary > ${\alpha}-tocopherol$ > GFSE. It would not be problem that addition of carnosine in uncooked ground of resulted in an increase of pH because the high pH could be advantageous on processing of meat. Antioxidative activity on lipid oxidation of cooked ground pork appeared to be in order of carnosine > rosemary > ${\alpha}-tocopherol$ > GFSE. Although the antioxidants were not lost their antioxidative }ctivities after cooking, their antioxidative activities in cooked ground pork were not higher than that of uncooked ground pork. That addition of carnosine increased the pH of cooked ground pork, too.
