Hongdeng) stored in controlled atmospheres (CA), in modified atmosphere packages (MAP) and in air (CK) were investigated in this paper. The results showed that CA and MAP treatments significantly inhibited fruit rot and flesh browning, kept firmness and fruit color, reduced ethylene and ethanol content in pulp, slowed down the increase of polyphenol oxidase (PPO) and peroxidase (POD) activity and malondialdehyde (MDA) content in comparison with CK. Meanwhile, CA treatments showed a better benefit of reducing ethylene and ethanol contents, inhibiting PPO and POD activities, declining rot rate and browning index compared to MAP. The fruit could be stored in CA conditions for 60 days without any off-flavor. The sweet cherries kept in CA with 5% O2 + 10% CO2 showed a better storability than that in CA with 5% O2 + 5% CO2.展开更多
