Developing bio-based and biodegradable materials has become important to meet current market demands, government regulations, and environmental concerns. The packaging industry, particularly for food and beverages, is known to be the world's largest consumer of plastics. Therefore, the demand for sustainable alternatives in this area is needed to meet the industry's requirements. This review presents the most commonly used bio-based and biodegradable packaging materials, bio-polyesters, and polysaccharide-based polymers. At the same time, a major problem in food packaging is presented: fungal growth and, consequently, food spoilage. Different types of antifungal compounds, both natural and synthetic, are explained in terms of structure and mechanism of action. The main uses of these antifungal compounds and their degree of effectiveness are detailed. State-of-the-art studies have shown a clear trend of increasing studies on incorporating antifungals in biodegradable materials since 2000. The bibliometric networks showed studies on active packaging, biodegradable polymers, films, antimicrobial and antifungal activities, essential oils, starch and polysaccharides, nanocomposites, and nanoparticles. The combination of the development of bio-based and biodegradable materials with the ability to control fungal growth promotes both sustainability and the innovative enhancement of the packaging sector.
开发生物基和可生物降解材料对于满足当前市场需求、政府法规和环境问题变得至关重要。包装行业，特别是食品和饮料包装行业，是世界上最大的塑料消费者。因此，需要在这一领域寻求可持续的替代品，以满足行业的要求。本综述介绍了最常用的生物基和可生物降解包装材料，生物聚酯和多糖基聚合物。同时，还提出了食品包装中的一个主要问题：真菌生长，进而导致食物变质。本文从结构和作用机制两方面阐述了不同类型的天然和合成抗真菌化合物。详细说明了这些抗真菌化合物的主要用途及其有效性程度。最新研究表明，自 2000 年以来，将抗真菌剂纳入可生物降解材料的研究呈明显增多趋势。文献计量网络显示，关于活性包装、可生物降解聚合物、薄膜、抗菌和抗真菌活性、精油、淀粉和多糖、纳米复合材料和纳米粒子的研究不断增加。生物基和可生物降解材料的发展与控制真菌生长的能力相结合，促进了可持续性和包装行业的创新增强。
