| Popis: | Keeping the quality and prolongation the shelf-life of stored at 0 0.5ºC packed under vacuum or modified (80%О2/20%СО2) atmosphere beef m. semimembranosus sprayed with 0.02% solution, containing 10 g.l-1 dihydroquercetin from Siberian larch (Larix sibirica Ledeb), 5 g.l-1 rosemary (Rosmarinus officinalis) extract and 1 g.l-1 L-ascorbic acid was studied. The experiments were carried out with five samples: control - air packaged; vacuum packaged; vacuum packaged and treated with 0.02% ternary antioxidant blend; packaged under modified atmosphere (80%O2/20%CO2); and packaged under rich in oxygen modified atmosphere, after spaying with 0.02% ternary antioxidant blend. Samples were stored 28 days (to 32 d post mortem) at 0 0.5ºC. The pre-treatment of beef with ternary antioxidant blend preserve the sensory scores and colour properties of beef, and inhibited total microbial growth, and development of Brochothrix termosphacta and pathogens to the end of storage (28 d at 0 0.5ºC), was found. The pre-treatment of beef with ternary antioxidant blend was not main factors which can affect the pH and free amino nitrogen changes in fresh beef. The pre-treatment of beef with 0.02% ternary antioxidant blend may be successfully used for preserving the quality and prolonging the shelf-life of beef m. semimembranosus packed under modified (80%О2/20%СО2) atmosphere. The shelf-life can extend with 75% compared to air packed meat, and with 7 days against only vacuum- or modified atmosphere packed beef. |
