研究了以不同体积分数混合的O2、CO2、N2气调包装,在(0±0.5)℃贮藏条件下对鲜枣(Ziziphus zizyphus)品质的影响。结果表明:经过90d的贮藏,不同体积分数的气调包装均能有效抑制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)含量的上升和硬度的下降;降低质量损失和乙醇积累量;减缓鲜枣果实中可滴定酸含量的下降和颜色变化以及还原糖含量上升;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。其中以气体体积分数为5%O2、2%CO2、93%N2的气调包装对鲜枣的保鲜效果最好。

After modified atmosphere packaging with different volume of O2,CO2,N2,fresh jujubes were stored under the condition of 0 ± 0. 5℃ for 90 days,and quality changes during the storage period were tested. Research results showed that modified atmosphere packaging can slow down the loss of reducing sugar,MDA,ethanol,weight,firmness,color changes and the contents of TA and prevent the loss of vitamin C,cyclic AMP and total flavone. The modified atmosphere packaging can effectively inhibit the senescence and loss of nutrients. The best volume ratio was5 % oxygen,2 % carbon dioxide and 93 % of nitrogen.
