Abstract

Crosslinked carboxymethyl starch（CCMS） was synthesized from potato starch,with epichlorohydrin as the crosslinking agent.Then,the properties of CCMS were compared with those of native potato starch,crosslinked starch（CS）,carboxymethyl starch（CMS） and carboxymethyl cellulose（CMC）,finding that CCMS paste is of excellent aging resistance,thermal stability,pH stability and shear stability.Moreover,the molecular structure and particle morphology of potato starch and the modified starches were characterized by means of FT-IR,ESEM and XRD,with the modification degree and the relationship between structure and properties being also analyzed.The results indicate that CCMS is of reasonable structure and excellent

Key words： potato starch; crosslinking; carboxymethyl; compound modification; properties
