Effect of Modified Atmosphere Package Storage on Postharvest Physiology and Quality of Early Mature Stage Fresh Jujube Fruits

Abstract:

Influence of package with 0.18 mm thickness of CPP bags with different volume fraction of O2, CO2, and N2 gasses on quality changes of early mature stage(less than 25% red surface color) fresh jujube fruits(Ziziphus zizyphus) were investigated during the 100 d storage period at (0±0.5) ℃. The results show that these modified atmosphere packages with different volume fraction of gasses slowed down the senescence of and nutrition decrease in the packed fruits. The rise of reducing sugar, MDA and ethanol accumulation, and the decrease of weight loss, firmness, color change and the contents of TA in the packed fruits were inhibited to varying degrees, while the losses of vitamin C, cyclic AMP and total flavone in the packed fruits were delayed. Package with volume fraction of 5% O2, 2% CO2 and 93% N2 exerted the best storage effect.
