AbstractThe effects of addition of vitamin E to pig diet and of calcium ascorbate injection in meat on the antioxidativestatus and meat quality (longissimus muscle) of pigs were investigated. The treatment consisted ofsupplementation with vitamin E (500 mg α-tocopheryl acetate/kg diet) for a minimum of 30 days to growingfinishing pigs before slaughter. Furthermore, meat samples (longissimus muscle) were injected with 10% byweight of a 1.5% calcium ascorbate solution. The dietary supplementation of fat soluble antioxidant vitamin Esignificantly (P<0.05) increased the concentration of α-tocopherol in meat (longissimus muscle). Lipid oxidationmeasured as TBARS, and antioxidative capacity (Fe2+/ascorbate induced) of meat were significantly (P<0.05)influenced by the supplementation with vitamin E, and the pH1 and driploss was improved. Water solubleantioxidant calcium ascorbate, injected in meat, increased the concentration of calcium (P<0.05) and ascorbicacid (P<0.05), and stabilized the colour (“a” value; P<0.05) in chill-stored meat and improved (P<0.05) theantioxidative capacity (Fe2+/ascorbate induced). Further research is needed to optimise the dosage.Key Words: pig, vitamin E, calcium ascorbate, lipid oxidation, meat quality
