Extraction of chitosan & its film-forming properties: A review

Abstract

Chitosan is a naturally-occurring polysaccharide produced from deacetylation of chitin. It is abundant in exoskeletons of marine creatures. Among of its interesting characteristics is its ability to bind fat and cholesterol, antimicrobial, and anti-oxidation properties. Due to its anti-microbial and anti-oxidation properties, chitosan has been used as films coatings for vegetables and fruits. This paper presents a review of current research in chitosan extraction as well as methodology for synthesizing film casings with it.
