Special Issue Information

Dear Colleagues,

Food packaging materials play a critical role in preserving the quality, safety, and freshness of products. These materials are designed to protect food from external factors such as air, moisture, light, and contaminants. At present, there is a wide range of packaging materials available, each with its own unique properties and advantages. Plastic, in particular, is one of the most commonly used materials due to its versatility, durability, and cost-effectiveness. However, the environmental impact of plastic packaging has raised various concerns, highlighting the need for alternative solutions. Currently, significant attention is being given to the development of active materials that not only extend the shelf life of products but are also biodegradable and environmentally friendly.

In this Special Issue, we aim to focus on the latest advancements and applications of alternative, biodegradable, and active food packaging materials. Full research articles and comprehensive review articles on this topic are welcome.

Currently, natural polymer materials with bactericidal properties are extremely popular. Unfortunately, although the biopolymer material itself is biodegradable, its enrichment with bactericidal compounds may affect the efficiency of biodegradation by natural soil microflora. Therefore, the primary objective of this study was to evaluate the utility of fungi belonging to the genus Trichoderma in facilitating the degradation of chitosan film modified with cinnamic acid and ellagic acid in the soil environment. Only two strains (T.07 and T.14) used chitosan films as a source of carbon and nitrogen. However, their respiratory activity decreased with the addition of tested phenolic acids, especially cinnamic acid. Addition of Trichoderma isolates to the soil increased oxygen consumption during the biodegradation process compared with native microorganisms, especially after application of the T.07 and T.14 consortium. Isolates T.07 and T.14 showed high lipolytic (55.78 U/h and 62.21 U/h) and chitinase (43.03 U/h and 41.27 U/h) activities. Chitinase activity after incorporation of the materials into the soil was higher for samples enriched with T.07, T.14 and the consortium. The isolates were classified as Trichoderma sp. and Trichoderma koningii. Considering the outcomes derived from our findings, it is our contention that the application of Trichoderma isolates holds promise for expediting the degradation process of chitosan materials containing bactericidal compounds.
