Storage Of Minimally Processed Cabbage In Different Packaging Systems

Abstract

The stability of fresh-cut cabbage packed in low density polyethylene under active modified atmosphere and in expanded polystyrene trays wrapped with PVC was evaluated. Fresh-cut product was stored for 16 days in a cold room at 5±1°C and 95±5% RH and in a refrigerated display, similar to the ones found in convenience stores. The following variables were analyzed: O2 and CO2 inside the package headspace, browning increment, luminosity, polyphenoloxidase and peroxidase activities, pH, titratable acidity, soluble solids, fresh mass loss, and ascorbic acid content. Stability of fresh-cut cabbage showed high in the temperature of 5°C when compared in the storage in the refrigerated display. Active modified atmosphere was not effective to extend the shelf life of fresh-cut cabbage when compared to the other treatments. LDPE packaging was more adequate for freshcut cabbage storage. However, PVC wrapping also presented satisfactory effects.877597602Almeida, M.E.M., Nogueira, J.N., The control of polyphenol oxidase activity in fruits and vegetables (1995) A Study of the Interactions Between the Chemical Compounds Used and Heat Treatment.
