不同运输时间对鲜食枣果实品质的影响

Effects of different transportation time on fruit quality of fresh jujube

  • 摘要: 为了探明鲜食枣在常规包装下的常温运输时间,以鲜食枣京沧1号蟠枣为试材,研究不同运输时间(0、2、3、4、5、6和7 d)对蟠枣品质的影响。结果表明,随着运输时间的延长,蟠枣腐烂率和质量损失率逐渐升高,运输5 d后,蟠枣腐烂率显著升高;果皮转红指数上升,色差L*值和b*值持续下降、a*值呈上升趋势;可溶性固形物含量呈先升高后降低的趋势,在运输5 d后达到峰值,为31%。为此,蟠枣运输时间应在5 d内,可较好地保持果实商品性,为鲜食枣的贮运和保鲜技术提供理论基础。

     

    Abstract: In order to investigate normal temperature transportation time of fresh jujube under conventional packaging, effect of different transportation times(0, 2, 3, 4, 5, 6, 7 days)on quality of fresh jujube was studied, Jingcang 1 was selected as experiment material.Results showed that, with extension of transportation time, decay rate and weight loss rate of jujube gradually increased, and fruit decay rate significantly increased after 5 days of transportation.Peel turning red index increased, while color difference values of L* and b* continued to decrease, and a* value showed a rising trend.Total soluble solids(TSS)content showed a trend of first increasing and then decreasing, and reached a peak of 31% after 5 days of transportation.Results could conclude that transportation time of flat jujube should be within 5 days, which could better maintain commercial value of fruit, and provide a theoretical basis for storage, transportation, and preservation technology of fresh jujube.
