Conserva？？o de piment？o verde minimamente processado acondicionado em diferentes embalagens plásticas

minimal processing of vegetables adds value to the final product for increasing its convenience and reducing the time to prepare meals. this study aimed to evaluate the conservation of minimally processed green peppers 'konan r', sliced and conditioned in different plastic packages. the fruits were selected, washed, and sanitized in a sodium hypochlorite solution (200 mg l-1), for 15 minutes. their slices (1.0 cm thickness) were sanitized in a sodium hypochlorite solution (50 mg l-1), for 5 minutes, and then conditioned in: 1) expanded polystyrene trays, covered with polyvinyl chloride film (pvc) 0.014 mm; 2) rigid polypropylene (pp) packages, with lid made of the same polymer; 3) bioriented polypropylene (bopp) 0.060 mm plastic bags. the product was stored at 5±0.1oc and rh of 95±1%, for 6 days. the following analyses were performed every 2 days: mass loss, titratable acidity and ascorbic acid contents, ph, color (expressed in l* and a* values), ？？and slices vigor. the plastic packages and storage time did not affect the ph, l* value, and slices vigor. the titratable acidity contents and a* value were affected by storage time. the polystyrene tray covered with pvc film led to greater mass loss and lower ascorbic acid content, in slices of green peppers stored at 5oc, for 6 days. thus, the pp package and the bopp plastic bag are preferable to condition minimally processed green pepper.
