摘　　要：为提高‘京沧1号’枣果实贮藏品质和商品性,以‘京沧1号’枣为试材,考察不同浓度水杨酸(10、30、50 mmol/L SA)结合微孔保鲜袋处理对‘京沧1号’枣保鲜效果的影响。结果表明,未使用微孔保鲜袋包装处理的‘京沧1号’枣在贮藏14 d后即出现明显的失水皱缩,品质劣变严重;仅使用微孔保鲜袋包装处理的‘京沧1号’枣保鲜效果不理想,微孔保鲜袋包装结合30 mmol/L SA处理效果最好,可使其贮藏期较未使用微孔保鲜袋处理组延长40 d左右。该处理能够有效延缓‘京沧1号’果实中可溶性固形物、可滴定酸等营养物质的消耗,延缓果实贮藏过程中失水皱缩和亮度、硬度的下降,维持相对较高的贮后可溶性糖、维生素C、总酚、可溶性蛋白等营养物质含量和抗氧化活性(P<0.05)。因此,微孔保鲜袋包装结合30 mmol/L SA处理是一种应用于‘京沧1号’枣的有效贮藏保鲜方法。It was necessary to improve the storage quality and commodity quality of Z.jujube‘Jingcang1’.The effects of different concentrations of salicylic acid(10,30,50 mmol/L SA)combined with microporous fresh-keeping bag treatment on the preservation effect of Z.jujube‘Jingcang1’were investigated.The results showed that SA treatment could effectively delay the decline of storage quality of'Z.jujube‘Jingcang1’.After 14 days of storage,the Z.jujube‘Jingcang1’,which was not packed with microporous plastic bag,was obviously dehydrated and shriveled and its quality deteriorated seriously.The fresh-keeping effect of Z.jujube‘Jingcang1’packed with microporous plastic bag was not ideal.Packaging with microporous plastic bag combined with 30 mmol/L SA treatment had the best effect,which could prolong its storage period by about 40 days compared with that of the group without microporous plastic bag.Compared with the control group,microporous plastic bag combined with 30 mmol/L SA treatment can effectively delay the consumption of total soluble solid,titratable acid and other nutrients in the fruit of Z.jujube‘Jingcang1’,delay the dehydration shrinkage,the decrease of brightness and fruit firmness of the fruit during storage,and maintain a relatively high content of soluble sugar,ascorbic acid,total polypheno,soluble protein and other nutrients and antioxidant activity after storage(P<0.05).Therefore,microporous plastic bag packaging combined with 30 mmol/L SA treatment is an effective method for the storage and preservation of Z.jujube‘Jingcang1’.
