Abstract

Effects of gamma irradiation on lipid components, antioxidative enzyme activities and ${\alpha}-tocopherol$ in beef (M. Semitendinosus and Longissimus dorsi) were investigated. The lipid components (total cholesterol, LDL-cholesterol, HDL-cholesterol, triglyceride and phospholipid) and the antioxidative enzyme activities (glutathione sulfur transferase, catalase and total superoxide dismutase) were not significantly changed by gamma irradiation up to 10 kGy (p>0.05). However, the contents of ${\alpha}-tocopherol$ in Longissimus dorsi significantly decreased with irradiation dose (P<0.05).
