Resumen:
Fresh-cut horticultural products have a very limited shelf-life and have been associated with several foodborne illnesses. In previous studies, natural antimicrobials green tea (GTE) and nisin have shown great effect on microbial control, while modified atmosphere packaging (MAP) with modified initial atmosphere (MIA) was great for nutritional preservation. The aim of this study was to select an adequate combination of those treatments to enhance safety, quality and shelf-life of fresh-cut beet leaves. Results shows synergistic behavior with the combination of 2.5% GTE, 500UI/g nisin and MAP with MIA for native microbiota, Listeria and E. coli control. During refrigerated storage, combined treatment showed a significant reduction in microbial counts and generate a "fortification" increasing greatly its total polyphenols content and antioxidant capacity. While control samples presented a shelf-life of less than 7 days, an adequate combination of technologies improved greatly the overall quality and prolonged shelf-life to at least 14 days.
