    摘要:

    研究了将不同体积分数混合的O2、CO2、N2充入0.18 mm的CPP包装袋中进行气调包装,在(0±0.5) ℃贮藏条件下对着色面积<25%的初熟鲜枣(Ziziphus zizyphus)品质的影响。结果表明,经过100 d的贮藏,不同体积分数的气调包装均能有效抑制初熟鲜枣果实衰老和营养物质流失,能不同程度地延缓果实中MDA(丙二醛)质量分数的上升和硬度的下降;降低质量损失和乙醇积累量;减缓初熟鲜枣果实中可滴定酸体积分数的下降和颜色变化以及还原糖质量分数上升;可有效防止VC、cAMP和总黄酮等营养物质的流失;同时能够较长时间地保持果实鲜亮的颜色。其中以5% O2、2% CO2、93% N2气体体积分数的气调包装对鲜枣的保鲜效果最好。

    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.
