Dietary Supplementation of Vitamin E to Feedlot Cattle Affects Beef Retail Display Properties

摘要

ABSTRACTBeef products from carcasses (n = 20) of cattle fed supplemental vitamin E and beef products from commodity carcasses (n = 20), used as controls, were compared to determine effects of increased vitamin E tissue levels on display appearance of fresh beef held in supermarket and simulated retail conditions. Meat from cattle fed supplemental vitamin E contained higher levels of α‐tocopherol (P<0.05) and, over time, exhibited less lipid oxidation, brighter lean color and lower discoloration. Monitoring supermarkets for discounted retail meats showed increased levels of α‐tocopherol in beef extended caselife and decreased the incidence of discounted beef pro
