The preparation and physicochemical properties of biodegradable konjac glucomannan-based films reinforced with bacterial cellulose and tea polyphenol for food packaging.

ABSTRACT: Biodegradable and edible packaging films derived from konjac glucomannan (KGM) are gaining popularity as promising candidates to replace petroleum-based plastics with the aim of alleviating environmental problems. However, their poor mechanical strength and lack of antioxidant activity have restricted their practical application in food packaging. Bacterial cellulose (BC), with a three-dimensional nanostructure and biodegradable and biocompatible properties, was chosen as a reinforcing agent to enhance the mechanical properties of KGM film. Film prepared with 15% BC displayed the highest tensile strength of 62.87 MPa and elongation at break of 38.17%, owing to the strong hydrogen bond interactions between the BC and KGM chains. Furthermore, tea polyphenols (TP), a type of natural antioxida
