如今，塑料包装是必不可少的。然而，不可生物降解的聚合物在寿命结束时的填埋处理所引起的巨大环境问题必须最小化并优先消除。该解决方案可以依赖于使用生物聚合物，特别是多糖。这些具有成膜特性的大分子能够产生有吸引力的可生物降解材料，可能适用于食品包装。尽管使用从不同来源获得的多糖具有所有优点，但主要与其低耐水性、机械性能和价格相关的一些缺点阻碍了其更广泛的使用和商业化。然而，随着对这一领域的关注和研究日益增加，已经有可能找到一些克服问题和找到解决办法的战略。本文综述了一些最常用的多糖在食品包装应用。
Plastic packaging is essential nowadays. However, the huge environmental problem caused by landfill disposal of non-biodegradable polymers in the end of life has to be minimized and preferentially eliminated. The solution may rely on the use of biopolymers, in particular polysaccharides. These macromolecules with film-forming properties are able to produce attracting biodegradable materials, possibly applicable in food packaging. Despite all advantages of using polysaccharides obtained from different sources, some drawbacks, mostly related to their low resistance to water, mechanical performance and price, have hindered their wider use and commercialization. Nevertheless, with increasing attention and research on this field, it has been possible to trace some strategies to overcome the problems and recognize solutions. This review summarizes some of the most used polysaccharides in food packaging applications.
