The perishability of fruits and vegetables poses significant challenges for their transportation and storage. Clove essential oil (CEO) is a natural preservative, but its high volatility and instability limit its practical application. In this study, a series of novel defective MIL-100(Fe)-x (D-MIL-100(Fe)-x, where x represents the molar ratio relative to iron: 1, 5, 10, or 15) were synthesized using trifluoroacetic acid (TFA) as a modulator and subsequently loaded with CEO to enhance stability and enable sustained release for peach preservation. Among these, D-MIL-100(Fe)-1 exhibited the highest CEO loading capacity of 610.6 mg/g, 1.45 times greater than that of conventional MIL-100(Fe). The composite demonstrated significant sustained-release behavior, releasing 42.3% of CEO over 16 days at 25 °C. D-MIL-100(Fe)-1/CEO showed a preservative effect comparable to that of the refrigerated group, offering enhanced versatility, convenience, and cost-effectiveness. This study provides a novel † Naiding Wang, Jun Zhang, and Rongpeng Li contributed equally to this work and should be considered co-first authors. defective MIL-100(Fe)-x for effective essential oil loading, providing a safe and biocompatible method for preserving fruits and vegetables.
