Effect of modified atmosphere packaging on chilling-induced peel browning in banana

Sucrier bananas (Musa AA Group; cultivar locally known as Kluai Khai) were stored at 10 °C, which results in chilling injury(CI).Fruitwas held in packages with and without a modified atmosphere (MA). Oxygen levels in the MA packages were about 12% while CO2 concentrations were about 4%. MA packaging resulted in less visible CI (i.e. greyish peel browning). Total free phenolics in the peel of control bananas decreased more rapidly than infruitheld in the MA package. Phenylalanine ammonia lyase (PAL) and polyphenol oxidase (PPO) activities in the peel of control bananas were considerably higher than in MA-packedfruit.Pulp softness, sweetness and flavour of MA-packedfruitwere better than in controlfruit.MA thus reduced CI symptoms. PAL and PPO activities may be causally related to CI-induced peel browning.
