Packaging made of plastic harms the environment. Thus, polysaccharide edible films are becoming a popular food packaging solution. Alginate is a biopolymer derived from seaweed that has the potential to create food packaging materials that are environmentally friendly and biodegradable. This article explores the potential use of nanocomposite coatings and films made from alginate as an alternative to petroleum-based polymers in the food industry. Alginate is desirable for food packaging due to its low cost, high nutritional value, renewability, low oxygen permeability, biodegradability, and biocompatibility. This article delves into alginate's history and extraction processes and covers techniques for modifying its physical and chemical properties using blended polymers and additives. Alginate-based coatings and films have been found to improve the mechanical properties and sensory characteristics of various food items and prolong the shelf life of perishable items by regulating oxygen and moisture levels and as a barrier against microbial growth. Further investigation is necessary to maximize the performance of alginate-based polymers in various food industry applications. Future prospects call on advancements in their physicochemical and functional characteristics to increase the acceptability of alginate-based nanocomposite coatings and films for biodegradable food packaging applications.
塑料包装对环境有害。因此，多糖可食用薄膜正成为一种受欢迎的食品包装解决方案。藻酸盐是一种源自海藻的生物聚合物，有潜力制造出环保且可生物降解的食品包装材料。本文探讨了由藻酸盐制成的纳米复合涂层和薄膜在食品工业中作为石油基聚合物替代品的潜在用途。藻酸盐因其成本低、营养价值高、可再生、氧气透过率低、可生物降解和生物相容性好而适用于食品包装。本文深入研究了藻酸盐的历史和提取过程，并介绍了使用共混聚合物和添加剂改变其物理和化学性质的技术。已发现基于藻酸盐的涂层和薄膜可改善各种食品的机械性能和感官特性，并通过调节氧气和水分含量以及作为防止微生物生长的屏障来延长易腐食品的保质期。有必要进行进一步研究，以最大限度地提高基于藻酸盐的聚合物在各种食品工业应用中的性能。未来的前景要求在其物理化学和功能特性方面取得进展，以提高基于藻酸盐的纳米复合涂层和薄膜在可生物降解食品包装应用中的可接受性。
