Special Issue Information

Dear Colleagues,

Plastic products are currently the most commonly used materials in food packaging, but this material has the defects of being difficult to degrade and unable to inhibit bacteria. Therefore, many researchers have been working on the development of new materials and natural products-based materials for food packaging. Natural polymers such as chitosan have good mechanical properties, biocompatibility and antibacterial properties, and are an ideal membrane -forming material. In the meanwhile, many natural extracts from plant by-products like seed, peel, root, husk, etc. are also added to improve the anti-spoilage bacteria and freshness of packaging materials. For example, a variety of essential oils have been shown to have good broad-spectrum antibacterial properties. Many phenolic hydroxyl groups in polyphenols can be bound to amino or carboxyl groups through hydrogen bonds, and hydrophobic benzene rings can also be bound to biological macromolecules through hydrophobic forces. It indicates that polyphenols could be an active component of polysaccharide membranes. Consequently, natural products have high application value and potential development in the field of food packaging.

In order to improve the mechanical properties, nutritional value and fresh-keeping ability of conventional sodium alginate edible composite membranes, a new type of edible composite film was prepared by adding water-blocking agent carnauba wax, plasticizer glycerin, antioxidant and nutritional enhancer sodium ascorbate on a basis of traditional sodium alginate composite film. In this study, the physical, mechanical and structural properties of different film components were investigated. The results showed the components did not simply combine, but produced interaction forces which improved the stability and mechanical properties of composite film. When the amount of calcium ascorbate was 0.4%, the water vapor transmittance of the composite film reached a minimum of 0.65 g·mm/(cm2·d·kPa), and the tensile strength and elongation at break reached the maximum, which were 398.64 MPa and 17.93%, respectively. Additionally, the sodium alginate-carnauba wax film exhibited better performance on the preservation of fresh-cut apples. Compared with other composite films, the color and hardness of fresh-cut apples coated with this composite film were better maintained, and the losses of titration acid content and soluble solid content were reduced. Moreover, the weight loss rate, increase in polyphenol oxidase activity and total colony count were inhibited. All results determined that the edible film has good application value in the field of fresh-cut fruit preservation, which provides a theoretical basis for further research on edible film.
