Abstract

Chitosan is a dietary fiber because of a linear polysaccharide composed of $\beta-(1{\rightarrow}4)$-linked 2-amino-2-deoxy-D-glucopyranose. In this study, control release system of vitamin C has been estimated in chitosan molecular network as a vitamin C carrier of controlled release. The amount of released vitamin C were decreased in higher amount of chitosan concentration. Especially, vitamin C were slowly released from chitosan solution in dialysis membrane when compared with vitamin C solution alone in dialysis membrane. These result assumed that chitosan driving force is dependent on chitosan molecular weight and cationic property of amino group with anionic property of vitamin C.
