Summary: Edible films and coatings, based on proteins, polysaccharides, and natural phenolic active substances, are being developed as effective alternatives to traditional plastic packaging due to increasing environmental concerns and the demand for high-quality foods. Gelatin, extracted from collagen, is an ideal material for food packaging, but its poor waterproof and mechanical properties restrict its application. Previous studies have shown that modifying gelatin with active ingredients and other bio-polymers can improve its properties and achieve desirable preservation effects. This review focuses on the preparation and applications of gelatin-based edible films, as well as the latest advances in gelatin-based biodegradable packaging and food preservation.

Summary: PVA hydrogels with high strength and toughness can be fabricated through dual physical and chemical cross-linking. The best mechanical properties are achieved by reacting at room temperature and subsequently undergoing freeze-thaw and annealing treatment. Additionally, the mechanical properties of PVA hydrogel increase and then decrease with the increase of molecular weight or mass fraction. By changing the reaction solvent, the mechanical properties of PVA hydrogel can be effectively adjusted.

Summary: Dyes, solvents, heavy metals, and oils pose a significant threat to water supplies globally. Advanced research has led to the development of green-adsorptive membranes that offer simple operation, high separation efficiency, low energy consumption, eco-friendliness, and affordability for water treatment. Nanocellulose, with its exceptional properties such as large specific surface area, anti-fouling behavior, high aspect ratio, and biodegradability, has been extensively studied as an excellent biomaterial in membrane filtration. The modification of nanocellulose has also shown promise in enhancing the performance of filtration membranes for heavy metal removal, oily water separation, and dye extraction.
