The results showed that ascorbic acid oxidase activity in the flesh of 'brumal Jujube' became significantly higher than in pericarp with the development of maturity; but these activities of peroxidase , Polyphenoloxidase and phenylalanine ammonia-lyase in flesh were lower than in pericarp . During the development from green to half-red then to red, the lignin and fibre contents in pericarp gradually increased higher than in flesh; ethanol content also increased , acetaldehyde content reached to a peak during the red maturity stage and then declined.

随着贮期的延长，冬枣果肉中乙醇和乙醛含量增加，乙醇发酵关键酶的活性逐渐升高；气调贮藏延缓了果实中乙醇和乙醛的积累，抑制了PDC和ADH的活性，显著提高了果实的贮藏品质；说明气调贮藏延缓了果实的乙醇积累；但CA_1比CA_2促进果实乙醇积累的作用较明显，表明冬枣对高浓度CO_2较敏感，这可能是枣果实不耐高CO_2的原因之一。
