To investigate the potential application value of dehydroabietic acid, 27 novel dehydroabietyl-1,2,4-triazole-5thioether-based derivatives were designed and characterized by IR, 1 H NMR, 13 C NMR, and LC-MS. Their antifungal activities were evaluated against five plant fungi, namely, Valsa mali, Colletotrichum orbiculare, Fusarium graminearum, Sclerotinia sclerotiorum, and Gaeumannomyces graminis; the results showed that compound 5h-1 (Co. 5h-1) exhibited a considerable inhibitory effect against V. mali. Moreover, in vivo experiments indicated that Co. 5h-1 had a certain protective effect on apple branches. The preliminary structure−activity relationship analysis suggested that the electron-withdrawing group on the benzyl group was significantly better than that of other substituent derivatives. Through electron microscopy analysis, it was found that Co. 5h-1 hindered the growth of mycelia, damaged their cell structure, and caused the large accumulation of reactive oxygen species (ROS). Preliminary research on the mode of action indicated that Co. 5h-1 could affect the activity of CAT by increasing the α-helix (0.790%), decreasing the βsheet (0.170%), which led to the accumulation of ROS. In addition, Co. 5h-1 also affected the activity of CYP51, hindered the biosynthesis of ergosterol, and increased cell membrane permeability. Overall, this above research proposed that Co. 5h-1 can be a novel leading structure for development of a fungicide agent.

“…Nanochitosan, or chitosan in nanoparticle form, has characteristics that make it suitable for the production of active packaging, especially because it is a source of antibacterial, the amino group (NH2), which plays an important role in antibacterial properties (Khairy et al, 2022;Abdullazadeh et al, 2023). Chitosan has a large surface area in the nanostructure, facilitating to interact effectively with microorganisms such as bacteria (Sen et al, 2022).…”

The objective of this study is to investigate the viability of employing waste derived from Syzygium cumini seeds as an environmentally sustainable antioxidant adjunct within the framework of PLA-PCL-Nanochitosan active packaging for food preservation. The method involves the manufacturing of a food packaging film by combining a PLA/PCL polymer blend with chloroform, followed by an evaporation process. This polymer blend is subsequently mixed with an extract derived from Syzygium cumini seed waste and nano chitosan. The mechanical mixing process takes 45 minutes and is carried out at a temperature of 160°C. The results of this study show that the active film has excellent mechanical properties, and an even surface texture, and was able to significantly reduce S. aureus colony counts by up to 98%. Active packaging film is also able to maintain pH and total volatile basic nitrogen (TVBN) in chicken breast.

“…Chitosan is a well-known biopolymer used for several years in different sectors of the industry and is known for its antibacterial [ 34 , 35 ] and antifungal properties [ 36 , 37 , 38 ]. The main advantages when using chitosan as matrix for a packaging material, beside its antimicrobial capabilities, is that it is biodegradable, thus being a sustainable choice for the food industry [ 39 , 40 ].…”

Edible coatings and films have been researched for more than three decades due to their ability to be incorporated with different functional ingredients or compounds as an option to maintain the postharvest quality of fruits and vegetables. The aim of this study was to evaluate the effect of three types of chitosan-based (CH) edible coatings obtained from medium and high molecular weight chitosan, containing ascorbic or acetic acid and sea buckthorn or grape seed essential oils on the physical–chemical and microbiological properties of organic strawberries and apple slices during cold storage at 4 °C and 8 °C. Scanning electron microscope images showed both a smooth structure and a fracture and pore structure on strawberry coatings and a dense and smooth structure on the apple slices coatings. Further, the edible coatings managed to reduce the microbial load of yeasts and molds of the coated strawberries during the storage period. Overall, the treatments preserved the ascorbic acid, total polyphenol content, and antioxidant activity for all the tested samples compared to the control sample, throughout the storage period. In addition, the water activity (aw) of the coated samples presented lower values (0.96–0.98) than the control samples. The obtained results indicate that the developed chitosan-based edible coatings could maintain the postharvest parameters of the tested samples, also leading to their shelf-life prolongation.
