Chitin is one of the most abundant natural polysaccharides in the world and it is mainly used for the production of chitosan by a deacetylation process. Chitosan is a bioactive polymer with a wide variety of applications due to its functional properties such as antibacterial activity, non-toxicity, ease of modification, and biodegradability. This review summarizes the most common chitosan processing methods and highlights some applications of chitosan in various industrial and biomedical fields. Finally, environmental concerns of chitosan-based films, considering the stages from raw materials extraction up to the end of life after disposal, are also discussed with the aim of finding more eco-friendly alternatives.
几丁质是世界上最丰富的天然多糖之一，主要用于通过脱乙酰化过程生产壳聚糖。壳聚糖是一种具有广泛应用的生物活性聚合物，由于其功能特性，如抗菌活性、无毒、易于修饰和可生物降解性。本文综述了最常见的壳聚糖加工方法，并强调了壳聚糖在各种工业和生物医学领域的一些应用。最后，还讨论了基于壳聚糖的薄膜的环境问题，考虑了从原材料提取到处置后的寿命结束的各个阶段，旨在寻找更环保的替代品。
