Abstract

Korean melons are renowned for their taste and nutritional qualities but face challenges such as chilling injury and browning during post-harvest storage, limiting their export potential. To address these issues, we compared melons stored in Controlled Atmosphere (CA) containers to those in Reefer Container (CON) under simulated export conditions. This study examines the effects of CA storage on the quality, metabolite changes, and volatile organic compounds (VOC) of Korean melons (Cucumis melo var. makuwa). CA-stored Korean melons showed increased concentrations of cutin monomers, suggesting reduced browning due to the expression of cutin-related genes. VOCs analysis revealed distinctive patterns in both Korean melon skin and juice, with specific compounds elevated in CA storage. The breakdown of linolenic acid into (E,Z)-2,6-nonadienal was reduced by approximately 30 % under CA storage, likely due to reduced oxygen availability. Twister-assisted VOCs analysis highlighted aroma differences, indicating potential effects on sensory perception. Solubility changes showed a 15 % increase in glyceric acid and a 20 % decrease in oxalate levels under CA storage, suggesting improved flavor and reduced harmful compounds. The freshness model based on VOCs indicated that CA-treated melons remained fresh approximately 4 d longer than control melons. In conclusion, CA storage improves the quality, freshness, and nutritional profile of Korean melons and offers valuable insights for refining post-harvest storage practices. Further research is warranted to explore the long-term effects of CA storage on other fruits and vegetables.

恒温贮藏可提高韩国甜瓜的货架期和质量：与冷藏集装箱出口的代谢比较分析

韩国甜瓜以其口感和营养品质而闻名，但在收获后贮藏过程中面临着冷害和褐变等挑战，限制了其出口潜力。为了解决这些问题，我们比较了在模拟出口条件下在可控气氛（CA）容器和冷藏集装箱（CON）中贮藏的甜瓜。本研究考察了 CA 贮藏对韩国甜瓜（Cucumis melo var.CA 贮藏的韩国甜瓜显示出角质素单体浓度的增加，表明由于角质素相关基因的表达，褐变程度降低。挥发性有机化合物分析表明，韩式甜瓜表皮和果汁中的挥发性有机化合物具有独特的模式，特定化合物在 CA 贮藏中会升高。在 CA 贮藏条件下，亚麻酸分解成 (E,Z)-2,6-壬二烯醛的过程减少了约 30%，这可能是由于氧气供应减少所致。捻线机辅助挥发性有机化合物分析凸显了香气差异，表明可能会对感官产生影响。溶解度变化显示，CA 储藏条件下甘油酸含量增加了 15%，草酸盐含量减少了 20%，这表明风味得到改善，有害化合物减少。基于挥发性有机化合物的保鲜模型表明，经 CA 处理的甜瓜比对照甜瓜的保鲜期长约 4 天。总之，CA 贮藏改善了韩国甜瓜的品质、新鲜度和营养成分，为改进采后贮藏方法提供了宝贵的见解。有必要进一步研究 CA 贮藏对其他水果和蔬菜的长期影响。

期刊介绍： The journal is devoted exclusively to the publication of original papers, review articles and frontiers articles on biological and technological postharvest research. This includes the areas of postharvest storage, treatments and underpinning mechanisms, quality evaluation, packaging, handling and distribution of fresh horticultural crops including fruit, vegetables, flowers and nuts, but excluding grains, seeds and forages. Papers reporting novel insights from fundamental and interdisciplinary research will be particularly encouraged. These disciplines include systems biology, bioinformatics, entomology, plant physiology, plant pathology, (bio)chemistry, engineering, modelling, and technologies for nondestructive testing. Manuscripts on fresh food crops that will be further processed after postharvest storage, or on food processes beyond refrigeration, packaging and minimal processing will not be considered.
