Effects of ${alpha}$-, ${gamma}$-, and ${delta}$-tocopherols at 0, 50, 100, 250, 500, and 1,000 ppm on the oxidative stability of lard during storage in the dark at $55^{circ}C$ for 7 days were studied by determining headspace oxygen content and peroxide value. The headspace oxygen content of the lard without tocopherol addition decreased from 21.1 to 14.4% and the peroxide value increased from 2.5 to 15.4 meq/kg lard for 7 days. The headspace oxygen depletion and the peroxide value of lard decreased by the addition of ${alpha}$-tocopherol at 50 ppm, but significantly increased at 250, 500, or 1,000 ppm. As the concentration of ${gamma}$-tocopherol or ${delta}$-tocopherol increased, the headspace oxygen depletion and the peroxide value decreased. ${alpha}$-Tocopherol at 250 ppm acted as a prooxidant in the autoxidation of lard. The concentrations of ${gamma}$- or ${delta}$-tocopherol to be applied to improve the autoxidative stability of lard may be 100-250 ppm.
