| Abstract:
Modified atmosphere packaging (MAP) is increasingly employed to extend the shelf-life of perishable food. Although applied mostly with non-respiring products, the technique offers considerable prospects as well for respiring products such as vegetables and fruits, which stay metabolically active during storage. Here Moderate Vacuum Packaging (MVP), a novel type of MAP, is presented, in which a product is stored in a refrigerator under 400 mB of pressure. The keepability of several fresh fruits and vegetables was assessed after MVP storage at 4 °C. The safety of MVP was evaluated by challenging mung bean sprouts and chicory endive with Listeria monocytogenes, Bacillus cereus, Yersinia enterocolitica and Salmonella typhimurium at 4, 7 and 10 °C. | |
