Pre- and postharvest chitosan coatings extend the physicochemical and bioactive qualities of minimally processed 'Crimson Seedless' grapes during cold storage.

Background: Food marketers desire residue-free fresh grapes although grapes have a short postharvest life. This study was performed to determine the influences of pre- and/or postharvest chitosan (Ch) coatings on postharvest quality of minimally processed (stem-detached) organic 'Crimson Seedless' berries. Berries were sorted as: (a) control (untreated berries); (b) preharvest Ch (dipping the clusters on the vine into 1% Ch 10 days before harvest at 20% soluble solid content (SSC)); (c) postharvest Ch (dipping the stem-detached berries into 1% Ch); and (d) pre + postharvest Ch.

Influence of different concentrations of 1-methylcyclopropene on the quality of tomato harvested at different maturity stages.

Background: A wide range of 1-methylcyclopropene (1-MCP) concentrations as well as various treatment durations have been studied in tomatoes by different researchers. However, little is known about interaction of 1-MCP doses and maturity stages of tomatoes. Therefore the effects of different concentrations of 1-MCP on storage and postharvest quality of 'Zorro' tomatoes harvested at mature green or pink maturity stages were investigated in a 2-year trial study.

Effects of modified atmosphere packing and honey dip treatments on quality maintenance of minimally processed grape cv. Razaki (V. vinifera L.) during cold storage.

Increasing pressure in food conservation sector to replace chemical applications has urged researchers to focus on studying new strategies of extending the postharvest life of produces. In such efforts, numerous materials have been tested for their effectiveness as well as suitability in organic consumption. In this study, effects of modified atmosphere packing (MAP) and honey solution dip on maintenance of quality of minimally processed table grape cv.
