Abstract：Chitosan is a natural biopolymer derived from the shells of crustacean. Chitosan has broad-spectrum
antimicrobial activity against a wide range of foodborne filamentous fungi, yeast, and bacteria, and at It also had
a potent inhibitory effect on lipid peroxidation. Chitosan coating could offer a protective barrier for moisture
and gas transfer and the loss of nutrients. These features make chitosan a potential natural food preservative or
coating material. This paper reviewed the applications of chitosan as food preservative for shelf life prolongation
of fresh meat products, seafoods and sausages.
