Abstract：The popularization and development of chilled beef are restricted by difficulties in tenderization and preservation. Modified atmosphere packaging (MAP) is a technique used for prolonging the shelf life of foods by modifying the composition of the atmosphere in which the foods are stored, and maintaining the modified atmosphere for a given duration to inhibit or delay the deterioration of food quality. In the present study, total colony number, pH, total volatile basic nitrogen (TVB-N), color, changes in gas concentrations in packages, and shear force were daily measured on chilled beef packaged with five different gas-permeable materials in a modified atmosphere (45% oxygen + 30% carbon dioxide + 25% nitrogen) during storage. The results showed that polypropylene-polyethylene-poly (ethylene terephthalate) was the best packaging material for chilled beef.
