Jujube is an important fruit species due to its high nutritional value and health benefits. However, the short shelf life of fruit causes quality losses, making it difficult to trade. This study was conducted to determine the effects of postharvest methyl jasmonate (MeJA) applications on the fruit quality and biochemical properties of 'Li' jujube (Ziziphus jujuba Mill.) cultivar. In the study, fruits were pre-cooled at 7 °C and 85 ± 5% humidity for 24 h and those with diseases, pests, and mechanical damage were eliminated. Then, MeJA was applied to the fruits at concentrations of 0.2 mM and 0.4 mM and stored at 0 ± 0.5 °C and 90 ± 5% humidity for 45 days and analyzes were performed at 15-day intervals.
This study showed that MeJA applications positively affected the postharvest quality of jujube fruit. MeJA-applied fruits exhibited lower weight loss and lower respiration rates, and MeJA applications helped preserve fruit color and maintained fruit firmness for a longer time. MeJA was effective in maintaining the total phenolic and flavonoid content in fruit content and the loss of vitamin C content was lower with MeJA application. MeJA was effective for determining soluble solids content (SSC), and titratable acidity and delayed ripening in fruit.
MeJA application increases the commercial value of fruits by reducing weight loss, slowing down the ripening process, and preserving higher nutritional content and antioxidant activities and suggest that it can be used as a feasible method for improving fruit protection strategies. MeJA application stands out as an effective method for extending the shelf life of jujube fruits by preserving their post-harvest quality and nutritional values.
枣因其高营养价值和对健康的益处而成为重要的水果品种。然而，果实较短的货架期会导致品质损失，使其难以进行贸易。本研究旨在确定采后茉莉酸甲酯（MeJA）处理对‘梨枣’（Ziziphus jujuba Mill.）品种果实品质和生化特性的影响。在该研究中，果实先在7℃、湿度85±5%的条件下预冷24小时，去除有病虫害和机械损伤的果实。然后，将浓度为0.2 mM和0.4 mM的MeJA施用于果实，并在0±0.5℃、湿度90±5%的条件下储存45天，每隔15天进行分析。
本研究表明，MeJA处理对枣果实的采后品质有积极影响。施用MeJA的果实重量损失较低，呼吸速率较低，且有助于保持果实颜色并在较长时间内维持果实硬度。MeJA能有效维持果实中的总酚和类黄酮含量，施用MeJA后维生素C含量的损失较低。MeJA对测定可溶性固形物含量（SSC）、可滴定酸度和延缓果实成熟有效。
施用MeJA通过减少重量损失、减缓成熟过程以及保持较高的营养成分和抗氧化活性来提高果实的商业价值，并表明它可作为一种可行的方法来改进果实保鲜策略。施用MeJA作为一种通过保持枣果实的采后品质和营养价值来延长其货架期的有效方法脱颖而出。
