“…Common host molecules include CD, crown ethers, cucurbiturils, cuproaromatics, and so forth, 72,73 where CD is widely used because it is non-toxic, easy to synthesize, and has a hydrophobic cavity to bind hydrophobic guests. 28 Yang et al 28 investigated the host-guest interaction between l-menthol and β-CD. The damaged coating swelled under the stimulus of water, which prompted the contact of free groups and self-healed within 20 min.…”

Food packaging materials are often inevitably and imperceptibly damaged during the transportation, handling, and storage, and the disruption of their integrity poses a challenge to food preservation. Food packaging materials with self‐healing capability can automatically repair the damaged areas and reconstruct original properties to avoid degradation of food quality and loss of nutrients. Various self‐healing materials based on dynamic covalent bonds and/or dynamic non‐covalent interactions have been developed and applied in food packaging in the forms of films and coatings at laboratory scale, and more efforts are required for the commercialization of these novel smart packaging materials. This is the first review to summarize the recent progress in the preparation of self‐healing packaging materials through different mechanisms, compare the self‐healing efficiency under different conditions, and highlight the potential applications of self‐healing films and coatings with recoverable mechanical and barrier properties and other functionalities (e.g., antimicrobial and anti‐fogging capacities). Finally, the future opportunities and challenges of applying self‐healing materials in food packaging are described.

“…In recent decades, the plant extracts have been widely used in the prevention of fruit and vegetable diseases and the development of green fruit and vegetable preservatives, they are aromatic and volatile components extracted from specific plant parts, most of which have antifungal effects ( Kaur et al, 2021 ). The common monomer plants such as cinnamaldehyde ( Li et al, 2019 ; Han et al, 2021 ), carvacrol ( Chen et al, 2021 ), menthol ( Yang et al, 2020 ), thymol, and vanillin ( Florencia Bambace et al, 2019 ) have been applied to the control of fruit and vegetable diseases and preservations and achieved good results ( Hyldgaard et al, 2012 ; Nazzaro et al, 2013 ). It is worth mentioning that thymol has been applied in various forms to the prevention and control of diseases and storage of fruits and vegetables in recent years, especially for the prevention and control of postharvest soft rot and brown spot ( Sun et al, 2021 ; Selvam et al, 2022 ).…”

With the increasing demand and quality requirement for the natural nutritious food in modern society, okra has attracted much attention because of its high nutritional value and remarkable functionality. However, the occurrence of postharvest diseases of fresh okra severely limited the application and the value of okra. Therefore, in this study, the dominant pathogens causing postharvest diseases such as soft rot were isolated from naturally decaying okra. It was identified as Mucor circinelloides by its morphological characteristics and standard internal transcribed spacer ribosomal DNA sequence. Furthermore, the biological characteristics of M. circinelloides were studied, and the inhibitory effect of thymol/KGM/LG (TKL) edible coating solution on M. circinelloides and its possible mechanism was discussed. In addition, TKL edible coating solution had a dose-dependent inhibitory effect on M. circinelloides, with a 50% inhibitory concentration (EC50) of 113.55 mg/L. The TKL edible coating solution at 960 mg/L of thymol completely inhibited mycelial growth and spore germination of M. circinelloides. The results showed that the best carbon source of M. circinelloides was maltose, the best nitrogen source was beef extract and potassium nitrate, the best pH was 6, the best temperature was 28°C, the best NaCl concentration was 0.5%, and the light was conducive to the growth of M. circinelloides. It was also observed by scanning electron microscope (SEM) that TKL was more likely to destroy the cell wall integrity of M. circinelloides, inhibit spore morphology and change mycelium structure. Meanwhile, the activity of chitinase (CHI), an enzyme related to cell wall synthesis of M. circinelloides, was significantly decreased after being treated by TKL with thymol at 100 mg/L (TKL100). The content of Malondialdehyde (MDA) in M. circinelloides decreased significantly from 12 h to 48 h, which may cause oxidative damage to the cell membrane. The activity polygalacturonase (PG), pectin methylgalacturonase (PMG), and cellulase (Cx) of M. circinelloides decreased significantly. Therefore, the results showed that TKL had a good bacteriostatic effect on okra soft rot pathogen, and the main bacteriostatic mechanism might be the damage of cell membrane, degradation of the cell wall, inhibition of metabolic activities, and reduction of metabolites, which is helpful to further understand the inhibitory effect of TKL on okra soft rot pathogen and its mechanism.
