Abstract

Changes in atmosphere composition and colour, tissue browning, decay,microbial viable cell count and sensorial attributes of fresh cut broccoli raab werestudied. Broccoli raab heads and young leaves were placed in polystyrene trays,covered with polyvinyl chloride (PVC) and polyamide/polyethylene (PA/PE) laminatedfilms and then stored under self controlled atmosphere (SCA) at 4°C for 16 d.Viable cell counts of packaged fresh-cut vegetables were lower than the legal limit forsafe consumption until the 12th day of storage in both PA/PE and PVC covered trays.However, after 8 and 12 d of storage, microbial counts of broccoli raab stored in PVCwere approx. 2 log cfu g-1 higher than those in PA/PE. Browning was only significantin samples packaged in PA/PE, probably due to high CO2 concentration inside thepackage. The results showed that PVC packaging was the best solution for freshbroccoli raab heads and young leaves stored at 4°C in SCA, leading to a shelf life of 12d compared to 7 d if vegetables were stored in PA/PE.
