| Abstract:
Longan (Dimocarpus longan Lour.) fruits were stored in different controlled atmospheres at 2°C to investigate the effects of different O2 and CO2 concentrations on enzyme activities, ethylene and ethanol contents, peel colour, total soluble solute and vitamin C contents, as well as fruit decay during storage periods. The results indicated that in comparison with modified atmosphere packaging (MAP), controlled atmosphere storage (CA) was associated with: a significantly reduction in fruit decay, inhibition of poly phenol oxidase (PPO) activity and prevention of skin browning, decreased ethylene productions and extension of storage-life of longan fruits. Fruit kept in CA of 15%CO2 + 4%O2 retained good taste and quality, without any deterioration or off-flavor development after 60 days of storage. | |
