“…Several biopolymers have been investigated to develop eco-friendly, biodegradable, and smart food packaging materials. Natural polymers such as polysaccharides, proteins, and lipids-based films provide various valuable properties like eco-friendly, biodegradability, biocompatibility, edibility, and sustainability ( Ali and Ahmed 2018a , 2018b ). Besides these, new trends have been emerged to improve the functionality of such packaging materials further in the direction of smart materials via loading various active functional materials such as antimicrobial agents, antioxidants, flavoring agents, colorants, nanoparticles, etc., ( Beigzadeh Ghelejlu et al., 2016 , Dominguez et al., 2018 , Irkin and Esmer 2015 , Yang et al., 2016 ).…”

Nowadays, biodegradable antimicrobial packaging materials draw substantial attention and are considered one of the preferred emerging technologies to be used in the food industry. In this study, we have reported developing a two-component, chitosan (CS) and polyvinyl alcohol (PVA) based films loaded with natural extract of Ocimum tenuiflorum via solvent casting technique. Experimental results showed that all the components were well dispersed, resulting in complete homogenous films. FTIR-ATR spectral analysis indicated strong interaction between the film matrix components, which also gets reflected by the films' physical properties. Transparent biodegradable films have resulted from the mixture and incorporation of the natural agent/extracts influenced light barrier, water resistance, moisture content (9.89–9.01%), and DPPH radical scavenging properties (antioxidant value ~41.1%) of the CS/PVA films. Therefore, this natural extract containing transparent CS/PVA-based films promises to be used in the food industry as packaging material to enhance food safety.

“…This growing concern has resulted in the faster development of plant-based foods and hybrid food products (from animal and plant sources), which have emerged as a new growing trend that can help the sustainability challenge [65]. The growing interest in the development of plant-based foods (including hybrid foods) has increased the number of studies on food hydrogels, which have the potential to improve the appearance, texture, flavor, mouthfeel, and functionality of these new products [20,37,[66][67][68].…”

Food hydrogels are biopolymeric materials made from food-grade biopolymers with gelling properties (proteins and polysaccharides) and a 3D network capable of incorporating large amounts of water. They have sparked considerable interest because of their potential and broad application range in the biomedical and pharmaceutical sectors. However, hydrogel research in the field of food science is still limited. This knowledge gap provides numerous opportunities for implementing their unique properties, such as high water-holding capacity, moderated texture, compatibility with other substances, cell biocompatibility, biodegradability, and high resemblance to living tissues, for the development of novel, functional food matrices. For that reason, this article includes a bibliometric analysis characterizing research trends in food protein–polysaccharide hydrogels (over the last ten years). Additionally, it characterizes the most recent developments in hydrogel induction methods and the most recent application progress of hydrogels as food matrices as carriers for the targeted delivery of bioactive compounds. Finally, this article provides a future perspective on the need to evaluate the feasibility of using plant-based proteins and polysaccharides to develop food matrices that protect nutrients, including bioactive substances, throughout processing, storage, and digestion until they reach the specific targeted area of the digestive system.

Wound dressings play a critical role in healing by maintaining a moist environment and protecting against infection. Here, we fabricate crosslinked films of chitosan–polyvinyl alcohol–genipin–curcumin to investigate the synergistic wound-healing effect of genipin and curcumin. The chemical bonding, morphology, strength, water retention capacity, curcumin release characteristics, and cytotoxicity of the films were investigated. The results showed a 192% increase in tensile strength and good water retention, and the infrared analysis and scanning electron microscopy micrographs confirmed genipin crosslinking and the presence of curcumin in the films, whose morphology was uniform and continuous. The curcumin-loaded films were found to have insignificant cytotoxicity against 3T3 fibroblast cells, proving their biocompatibility. The curcumin dissolution tests determined the amount of curcumin released from the films with time, and assessed the release characteristics to be sustained at all pH levels. In vivo trials were carried out on rodents to evaluate the wound-healing effects of the films, and the results showed that the curcumin-incorporated crosslinked films accelerated wound healing compared to the uncrosslinked and curcumin-absent films, confirming their effectiveness for wound healing.
