  • Composite matrix containing chitosan derivatives and a process for making the same
    Publication number: 20040033265
    Abstract: A method for preparing a composite matrix containing chitosan derivatives, comprising the steps of: (a) providing an anionic chitosan derivative solution (A); (b) providing a cationic polysaccharide solution (B); and (c) mixing solution (A) and solution (B) to form microcapsules. Metallic ion cross-linking agent and/or natural protein solution can be added optionally to adjust the mechanical strength of the shell and the interior physic state of the microcapsules.
