A biocomposite film composed of biopolymers chitosan (CS), gelatin (GE) and allantoin (AT) was fabricated by solution casting technique. The functional group interaction of the biocomposite films was inspected through the Attenuated total reflectance Fourier transform spectrometer (ATR-FTIR). The morphological changes and crystallinity of biocomposite films with varied ratios of chitosan/gelatin (CS/GE) and allantoin were examined under Scanning electron microscope (SEM) and X-ray diffractometer (XRD). The water-absorbing capacity was found enhanced by an increase in the chitosan ratio. The biocomposite films exhibit good antioxidant, anti-inflammatory properties. The biocomposite films also display enhanced stability with steady degradation under the PBS medium. The biocomposite films reveal improved antibacterial activity against Escherichia coli (E.coli) and Staphylococcus aureus (S.aureus). Blood compatibility studies explore the non-hemolytic nature. The in vitro cytotoxicity by MTT assay shows excellent biocompatibility. The fibroblast adhesion on the biocomposite film displays enhanced proliferation and viability. These significant biological properties of biocomposite film make it an appropriate candidate for wound dressing application.

Two plasticizers with distinct properties are carefully studied in this research for their suitability in creating biocomposite edible film products. The study uncovers films' physical, tensile, and biodegradability attributes, using snakehead gelatin and ĸ-carrageenan in different concentrations, with sorbitol or glycerol as plasticizers. The biomaterials of the edible film consist of snakehead gelatin () 2% (/); ĸ-carrageenan at concentrations of 1%, 1.

The study aims to evaluate how bacteriocin and extracellular polymeric substances (EPS) can influence the development of active packaging for food. The components might enhance the performance of packaging materials in terms of their physicochemical properties and their effectiveness in preserving food. Bacteriocin and EPS exert a significant effect in blocking the transmission of UV and visible light radiations.

Electrospinning is a versatile technique for obtaining nano/micro fibers which are able to significantly change the active properties of composite materials and bring in new dimensions to agri-food applications. Composite bio-based packaging materials obtained from whey proteins, functionalized with thyme essential oil (TEO) and reinforced by electrospun polylactic acid (PLA) fibers, represent a promising solution for developing new active food packaging using environmentally friendly materials. The aim of this study is to obtain and characterize one-side-active composite films covered with a PLA fiber mat: (i) WF/G1, WF/G2, and WF/G3 resulting from electrospinning with one needle at different electrospinning times of 90, 150, and 210 min, respectively, and (ii) WF/G4 obtained with two face-to-face needles after 210 min of electrospinning.

This study compared the use of cellulose nanofibrils (CNF) and lignocellulose nanofibrils (LCNF) in different concentrations to reinforce the poly(vinyl alcohol) (PVA) matrix. Both nanofillers significantly improved the elastic modulus and tensile strength of PVA biocomposite films. The optimum concentration of CNF and LCNF was 6% relative to PVA, which improved the tensile strength of the final PVA biocomposite with CNF and LCNF by 53% and 39%, respectively, compared to the neat PVA film.
