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7d)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5d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5d后达到峰值,为31%。为此,蟠枣运输时间应在5d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。
In order to investigate normal temperature transportation time of fresh jujube under conventional packaging,effect of differ-ent 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 in-creasing 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.
