Chitin is the most abundant natural amino polysaccharide and is estimated to be produced annually almost as much as cellulose, and recent progress in chitin chemistry is quite noteworthy as mentioned in this paper.Abstract:
Chitin is the most abundant natural amino polysaccharide and is estimated to be produced annually almost as much as cellulose. It has become of great interest not only as an underutilized resource, but also as a new functional material of high potential in various fields, and recent progress in chitin chemistry is quite noteworthy. The purpose of this review is to take a closer look at chitin and chitosan applications. Based on current research and existing products, some new and futuristic approaches in this fascinating area are thoroughly discussed.read more

Influence of α-tocopherol on physicochemical properties of chitosan-based films
TL;DR: In this paper, the effects of the incorporation of a-tocopherol in chitosan-based films were evaluated and it was shown that the addition of this compound to chitosa-based film leads to a significant reduction in tensile strength from 34.06 to 16.24 MPa, and elongation at break from 53.84 to 23.12%.
