Abstract: Polysaccharides and modified polysaccharides have been widely applied recently as the safe, non-toxic and effective fresh-keeping materials. The applications of polysaccharides and modified polysaccharides in film-coating preservation of fruits and vegetables as well as eggs are summarized in this paper. The mechanisms of the preservation and the film-coating methods were explored. The future development directions and application prospects of polysaccharides in film-coating preservation were proposed.
