ABSTRACT This study was conducted to determine the change of fruit quality properties of jujube fruit (Ziziphus jujuba) without stalk and with the stalk during storage. The fruit without and with stalk were stored at 0 ± 0.5°C and 90 ± 5% RH during 45 days. Also, fruit were placed inside modified atmosphere packing (MAP). The presence of the stalk of the fruit was effective in reducing quality losses in storage. The weight loss, decay ratio and vitamin C loss of fruit that were stored without stalk were higher. There was no change in soluble solids content and acidity ratio depending on fruit stalk presence. Total phenolic, total flavonoid, and antioxidant activity values were lower in fruit without stalk at the end of the storage. With the MAP application, the weight loss and decay rate of the fruit decreased in storage. In addition, fruit firmness, acidity, and vitamin C losses were lower in MAP-treated fruit. At the end of the storage, total phenolic, total flavonoid, and antioxidant activity values were higher in fruit with MAP. As a result, quality losses in fruit without stalk were higher than fruit with stalk. MAP reduced losses of quality in fruit without stalk.

冷贮期无梗和有梗枣果实品质特性的变化

摘要 本研究旨在确定无梗和有梗枣果实（Ziziphus jujuba）在贮藏过程中果实品质特性的变化。在 0 ± 0.5°C 和 90 ± 5% RH 的条件下，将无梗和有梗的果实储存 45 天。此外，水果被放置在气调包装 (MAP) 内。水果茎的存在可有效减少储存过程中的质量损失。无梗贮藏的果实失重率、腐烂率和维生素C损失率较高。可溶性固形物含量和酸度比没有变化，这取决于果梗的存在。在贮藏结束时，无茎果实的总酚、总黄酮和抗氧化活性值较低。应用 MAP 后，果实在贮藏过程中的失重和腐烂率降低。此外，MAP 处理的水果的水果硬度、酸度和维生素 C 损失较低。在贮藏结束时，MAP 处理的果实的总酚、总黄酮和抗氧化活性值较高。因此，无梗果实的质量损失高于有梗果实。MAP 减少了无茎果实的质量损失。
