Summary: Proteins and polysaccharides are commonly used to prepare eco-friendly packaging materials. However, films based on proteins or polysaccharides alone often have poor performance, so combining them is necessary to improve properties. In this study, enzyme technology was used to prepare films with sodium caseinate-carboxymethyl chitosan, incorporating epigallocatechin gallate as bridging molecules and antibacterial agents. The films showed improved mechanical properties, antibacterial activity, and free radical scavenging ability with the increase of epigallocatechin gallate and tyrosinase content. This work provides an efficient enzymatic method to prepare films with good strength and antibacterial properties for improving food storage quality.

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: Native starches have low solubility and stability, which can be improved through modifications. Porous starch, as a modified version, has enhanced adsorptive efficiency and solubility compared to native starch. However, it also has drawbacks such as weak mechanical strength and low thermal resistance. Modified porous starches have been developed to address these issues and show improved adsorption capacity and stability. Different modification methods can be used to prepare and characterize modified porous starch, which can be utilized as efficient adsorbents and encapsulants in various fields.
