Effect of supercooling on storage ability of different beef cuts in comparison to traditional storage methods

The effect of supercooling on different beef cuts was evaluated compared with traditional storage methods. Beef striploins and topsides were stored under freezing, refrigeration, or supercooling conditions and their storage ability and quality were analyzed during 28 days of storage. The total aerobic bacteria, pH, and volatile basic nitrogen were higher in the supercooled beef than in the frozen beef, but lower than in the refrigerated one, regardless of the type of cut. In addition, the discoloration of frozen and supercooled beef was slower than that of refrigerated beef. The results in storage stability and color indicate that supercooling can prolong the shelf-life of beef compared to refrigeration due to its temperature characteristic. In addition, supercooling minimized the problems of freezing and refrigeration, including ice crystal formation and enzyme-based deterioration; therefore, the qualities of topside and striploin were less affected. Collectively, these results indicate that supercooling can be a beneficial storage method for extending the shelf-life of different beef cuts.
