摘要

食品行业被认为是因包装而产生塑料垃圾的主要行业之一。可持续和可降解的包装解决方案是当务之急。事实证明，生物聚合物有望替代石油基聚合物。主要原因是生物聚合物具有抗菌性和可降解性等多种内在特性。本研究的主要目的是开发基于壳聚糖（CS）/纳米晶纤维素（NCC）和聚乳酸（PLA）的生物膜。生物膜采用滴注法制备。通过扫描电镜、傅立叶变换红外光谱、XRD、DSC 和热重分析对所制备的生物膜进行了表征。通过机械测试、水溶性、孔隙率、抗氧化性和抗菌活性检测了生物膜的性能。开发的生物膜可以解决食品包装行业面临的环境污染问题。

Developing of nanocellulose loaded chitosan-polylactic acid biofilms for green food packaging

The food industry is considered one of the main contributors to plastic waste due to packaging. Sustainable and degradable packaging solutions are the need of the hour. Biopolymers have proved to be a promising replacement for petroleum based polymers. The main reason is their various intrinsic properties like antimicrobial nature and degradability. The main objective of this study was to develop chitosan (CS)/nanocrystalline cellulose (NCC) and polylactic acid (PLA) based biofilms. The biofilms were developed using the drop casting method. The developed biofilms were characterized by SEM, FTIR, XRD, DSC, and thermogravimetric analysis. The performance of the biofilms was checked using mechanical testing, water solubility, porosity, antioxidant, and antibacterial activity. The developed biofilms can solve the issues of environmental pollution being faced by the food packaging industry.
