•Structure and properties for different CM-starches were investigated.•DS of CM-PG was higher than that of CM-WS under equivalent modification conditions.•The Mw increased for CM-PG with increasing DS whereas Rz was nearly constant.•Carboxymethylation modification resulted in a greater increase of S...
