Edible coatings prevent physicochemical and biological food deterioration. Using bioactive compounds like essential oils can enrich films. In this study, edible films from chitosan (C), casein (Z) and oregano (OEO) were developed, and their physicochemical, barrier, antimicrobial, antioxidant, and structural properties (FTIR, SEM) were investigated. The C1Z3 ratio had good mechanical and inhibitory properties, and OEO improves flexibility, barrier, hydrophobic, antimicrobial, and antioxidant properties. The physicochemical and microbiological properties of cherry tomatoes were affected by C1Z3 and C1Z3O1.5 coatings. Coated fruits were stored at 4 °C for 32 days. The best results for weight loss, shrinkage, and titratable acidity were found to be 17.88%, 31.12%, and 0.15% in C1Z3O1.5 coated cherry tomatoes, respectively.The TMAB of C1Z3O1.5 coated fruits was less than detectable and the fungal growth was inhibited for 28 days. Accordingly, by adding OEO to chitosan/casein coatings, the spoilage process of cherry tomatoes was delayed for long-term storage.

UI MeSH Term Description Entries
D009822 Oils, Volatile Oils which evaporate readily. The volatile oils occur in aromatic plants, to which they give odor and other characteristics. Most volatile oils consist of a mixture of two or more TERPENES or of a mixture of an eleoptene (the more volatile constituent of a volatile oil) with a stearopten (the more solid constituent). The synonym essential oils refers to the essence of a plant, as its perfume or scent, and not to its indispensability.
