Comparison of pesticide-free and conventional production systems on postharvest quality and nutritional parameters of peppers in different storage conditions

Abstract The peppers were grown using either pesticide-free or conventional production systems and stored at 8 °C in one of four storage methods, i.e. regular atmosphere (control), cling film (CF), modified atmosphere packaging (MAP) or a proprietary controlled atmosphere (CA) storage system (Palliflex™, PL) of 2 kPa O 2  + 3 kPa CO 2 . Internal atmospheres created by the MAP were periodically assessed during storage, and O 2 and CO 2 levels in both pecticide-free and conventionally-grown peppers were suitably maintained within recommended limits, 3–5 kPa O 2  + 2–8 kPa CO 2 . Weight loss of peppers stored in PL was lower (
