Abstract: Konjac glucomannan is a natural polymer with a wide range of sources, low price, excellent film-forming, biocompatibility, degradability and renewability. In many researches on composite materials based on konjac glucomannan, konjac glucomannan-based antibacterial active packaging film has received extensive attention and shown broad application prospects in the field of food packaging. In this paper, the structure and properties of konjac glucomannan and the preparation method of the composite film, as well as the preparation, functional properties and the research progress of antibacterial active packaging film based on konjac glucomannan are reviewed.
