大规模制造的增加和塑料在日常生活的许多方面的普遍使用对环境产生了不利影响。因此,这些担忧增加了气候变化的可能性,由于燃烧常规的二氧化碳排放,不可生物降解的聚合物。因此,可生物降解的明胶和壳聚糖聚合物正在被创造为在各种应用中不可生物降解的聚合物材料的可持续替代品。壳聚糖是唯一天然存在的阳离子碱性多糖,一种众所周知的由几丁质衍生的可食用聚合物。壳聚糖的生物活性,比如它的抗氧化剂,抗癌,和抗菌特性,最近引起了研究人员的兴趣。同样,明胶是一种天然存在的聚合物,源自胶原蛋白的水解分解,并由于其独特的氨基酸组成而具有多种药用优势。在这次审查中,我们概述了最近的研究重点是壳聚糖和明胶聚合物在各个领域的应用。其中包括使用明胶和壳聚糖作为食品包装,抗氧化剂和抗菌性能,包封生物活性物质的性质,组织工程,微囊化技术,水处理,和药物输送。这篇综述强调了研究不可降解塑料可持续选择的重要性。它展示了明胶和壳聚糖聚合物在解决环境问题和推动不同行业进步方面的多种用途。
Increased mass manufacturing and the pervasive use of plastics in many facets of daily life have had detrimental effects on the environment. As a result, these worries heighten the possibility of climate change due to the carbon dioxide emissions from burning conventional, non-biodegradable polymers. Accordingly, biodegradable
gelatin and chitosan polymers are being created as a sustainable substitute for non-biodegradable polymeric materials in various applications. Chitosan is the only naturally occurring cationic alkaline polysaccharide, a well-known edible polymer derived from chitin. The biological activities of chitosan, such as its antioxidant, anticancer, and antimicrobial qualities, have recently piqued the interest of researchers. Similarly,
gelatin is a naturally occurring polymer derived from the hydrolytic breakdown of collagen protein and offers various medicinal advantages owing to its unique amino acid composition. In this review, we present an overview of recent studies focusing on applying chitosan and
gelatin polymers in various fields. These include using
gelatin and chitosan as food packaging, antioxidants and antimicrobial properties, properties encapsulating biologically active substances, tissue engineering, microencapsulation technology, water treatment, and drug delivery. This review emphasizes the significance of investigating sustainable options for non-biodegradable plastics. It showcases the diverse uses of
gelatin and chitosan polymers in tackling environmental issues and driving progress across different industries.
