Abstract

Background: Cherry tomatoes are prone to postharvest deterioration and spoilage at room temperature, whereas chemical preservatives pose safety and environmental risks. Clove essential oil (CEO) has excellent antibacterial activity but is limited by high volatility, poor water solubility and dosage sensitivity. Cyclodextrin metal-organic frameworks (β-CD-MOFs) can improve CEO stability, but their poor processability and aqueous dispersibility hinder fruit preservation applications. Chitosan (CS), a natural hydrogel with film-forming and antibacterial properties, offers an ideal matrix to address these limitations.

Results: A CEO-loaded CS/β-CD-MOFs composite coating (CS-CEO/MOFs) was constructed and evaluated on cherry tomatoes stored at 25 °C via physicochemical analysis, electronic eye color detection and texture profile analysis (TPA). Compared with control, CS and high-concentration CEO-chitosan (CS-CEO-H) groups, high-concentration CS-CEO/MOFs (CS-CEO/MOFs-H) delayed spoilage. Principal component analysis of electronic eye data showed the recognition index (a parameter reflecting the distinguishability of color characteristics among groups) increased from -3 (day 0) to 97-98 (days 6-21), indicating distinct inter-group ripening rate differences. TPA results indicated CS-CEO/MOFs-H slowed hardness decline (effect positively correlated with hydrogel concentration) and maintained higher soluble sugar, vitamin C and titratable acid contents, as well as reduced weight loss, extending room-temperature shelf life to 21 days.

Conclusion: The CS-CEO/MOFs coating combined the gas barrier property of CS and the controlled release capability of β-CD-MOF, forming a synergistic fresh-keeping mechanism. As a safe, natural preservative, it provides a promising solution to reduce cherry tomato postharvest losses and lays a foundation for the development of plant-derived composite preservatives with controlled-release and gas barrier synergistic properties. © 2026 Society of Chemical Industry.

丁香精油负载壳聚糖/环糊精金属有机骨架（β-CD-MOFs）复合涂层对圣果保鲜效果的增强

背景：樱桃番茄在室温下容易采后变质和变质，而化学防腐剂则存在安全和环境风险。丁香精油（CEO）具有优良的抗菌活性，但受挥发性高、水溶性差和剂量敏感性的限制。环糊精金属有机骨架（β-CD-MOFs）可以提高CEO的稳定性，但其加工性和水分散性较差，阻碍了水果保鲜的应用。壳聚糖（CS）是一种具有成膜和抗菌特性的天然水凝胶，为解决这些限制提供了理想的基质。结果：构建了ceo负载CS/β-CD-MOFs复合涂层（CS- ceo /MOFs），并通过理化分析、电子眼颜色检测和纹理分析（TPA）对25°C保存的圣女果进行了评价。与对照、CS和高浓度ceo -壳聚糖（CS- ceo - h）组相比，高浓度CS- ceo /MOFs （CS- ceo /MOFs- h）组延缓了腐坏。电子眼数据的主成分分析表明，识别指数（反映群体间颜色特征可分辨性的参数）从-3（第0天）增加到97-98（第6-21天），表明群体间成熟速度差异明显。TPA结果表明，CS-CEO/MOFs-H减缓了硬度下降（与水凝胶浓度正相关），保持了较高的可溶性糖、维生素C和可滴定酸含量，减轻了失重，将室温保质期延长至21天。结论：CS- ceo / mof涂层结合了CS的阻气性能和β-CD-MOF的控释能力，形成了一种协同保鲜机制。作为一种安全的天然防腐剂，它为减少樱桃番茄采后损失提供了一种有前景的解决方案，为开发具有控释和阻气协同特性的植物源复合防腐剂奠定了基础。©2026化学工业协会。

期刊介绍： The Journal of the Science of Food and Agriculture publishes peer-reviewed original research, reviews, mini-reviews, perspectives and spotlights in these areas, with particular emphasis on interdisciplinary studies at the agriculture/ food interface. Published for SCI by John Wiley & Sons Ltd. SCI (Society of Chemical Industry) is a unique international forum where science meets business on independent, impartial ground. Anyone can join and current Members include consumers, business people, environmentalists, industrialists, farmers, and researchers. The Society offers a chance to share information between sectors as diverse as food and agriculture, pharmaceuticals, biotechnology, materials, chemicals, environmental science and safety. As well as organising educational events, SCI awards a number of prestigious honours and scholarships each year, publishes peer-reviewed journals, and provides Members with news from their sectors in the respected magazine, Chemistry & Industry . Originally established in London in 1881 and in New York in 1894, SCI is a registered charity with Members in over 70 countries.
