Résumé

Food safety is one of the main issues for the fresh-cut (FC) industry, which needs alternatives to chlorine disinfection in order to avoid some of their disadvantages. Escherichia coli has been reported as a pathogen in FC vegetables. The current work studied the efficacy of 5 and 10 kJ/cm2 UV-C on FC Bimi® broccoli (Brassica oleracea Italica Group x Alboglabra Group) inoculated with 6 cfu/g of E. coli 510T. Just after radiation, samples were packed in polypropylene baskets in air, and stored in darkness throughout 22 days at 5°C or 17 days at 15°C. On the processing day, both 5 and 10 kJcm-2 UV-C reduced the E. coli load in 1.5 cfu/g. Compared to control, FC Bimi® treated with both UV-C doses showed a continuous decrease of the E. coli load throughout shelf-life, reaching after 22 days at 5°C around 3.5 log cfu/g reductions compared to control. In contrast, when both UV-C treated samples were stored at 15°C, after 10 days no significant E. coli reductions compared to control was found. As main conclusion, combined moderate UV-C and storage at 5°C in air was a practical method to reduce E. coli growth on inoculated FC Bimi® broccoli throughout 22 days of shelf life.
