The primary challenges in fruit and vegetable preservation include extending storage duration while preserving sensory quality and nutritional value. In this study, sesbania gum (SG) was oxidized to prepare oxidized sesbania gum (OSG). An OSG/ZnO composite film was subsequently prepared, combining OSG, sodium carboxymethyl cellulose (CMC), and nano-zinc oxide (nano-ZnO). The preparation technology was determined via a response surface optimization experiment. When the addition amount of nano-ZnO exceeded 0.3 mg/mL, the composite films exhibited an antibacterial rate of over 90% against E. coli and S. aureus. For wampee (Clausena lansium (Lour.) Skeels) preservation, a OSG/ZnO-0.3 film was directly applied as a coating. The findings demonstrated favorable results in terms of the rate of rotting, soluble solids, and titrable acidity, effectively prolonging wampee fruit storage. This suggests the potential of an OSG composite film with nano-ZnO as a promising fruit packaging material, thereby expanding the application of SG and wampee fruit preservation.

Summary Whey protein concentrate (WPC) and carboxymethyl cellulose (CMC) were abundant in nature and biodegradable raw materials, which have a wide range of prospects for developing bioactive food packaging. In order to exploit the complementary functional properties, in this study CMC was incorporated into WPC films and modified by transglutaminase (TG). The physicochemical properties and structure characteristics of the composite films were investigated. Results showed that CMC as a filler of the protein network significantly improved the properties of WPC films, while TG contributed to the mechanical properties. The composite (1:1) film containing 10 U/gprotein of TG possessed a maximum tensile strength of 13.34 MPa compared to the WPC film. The addition of CMC and TG effectively improved the structure of the film, reducing the pore diameterr, so the composite film with TG at 10 U/gprotein showing a dense structure, with improved light transmission (37.42%) and water vapour transmission (5.06). FT‐IR and SEM results reflected that TG induced covalent cross‐linking between proteins and WPC and CMC had good compatibility. These suggest that the coexistence of CMC and TG has positive effect on the formation of composite films prepared by TG cross‐linking WPC and CMC blends, which provided a promising alternative method for the development of good edible films or coatings for food packaging in the future.

Pectin and sodium alginate (SA) composite films were prepared by adding various concentrations of microfibrillated cellulose (MFC) via solvent casting using glycerol as a plasticizer. Herein, elephant egesta was turned into cellulose fibers from which MFC was extracted. This paper aims to examine the reinforcing property of MFC on the pectin/SA matrix. Fibrous morphology, qualitative analysis, crystallinity, and thermal stability of MFC were confirmed through SEM, FT‐IR, XRD, and TGA‐DTA analysis, respectively. The impact of various compositions of MFC (0.5%, 1%, 2%, and 5%) on the biopolymeric blend was analyzed based on mechanical and optical properties, hygroscopicity, and hydrophilicity. The outcomes revealed that adding MFC to 5% enhances the film's tensile strength by 51%. The produced film also served as a successful barrier against UV–visible light. Moreover, it exhibits a tremendous increase in contact angle and a decrease in properties such as elongation at break, moisture content (MC) and water solubility (WS). Therefore, MFC can be an excellent reinforcing agent in biodegradable polymer composites, which finds application in the food packaging industry.Highlights Microfibrillated cellulose was successfully extracted from elephant egesta and characterized. Energy efficient method of extraction. Pectin/SA films were incorporated with the extracted MFC via solvent casting. Prepared films show enhanced tensile strength and UV–visible barrier property which makes them suitable for packaging purposes. Bio‐based polymers reduce environmental pollution.
