Abstract: The paste properties of carboxymethyl starch have been studied, including the gelatinization temperatrue,freeze-thaw stability,clarity and the anti-mycotic charicteristics,the effects of temperatme,concentration rotation,rate and pH values and the effects of media such as cane sugar,sodium chloride and chloridion.The results indicated that carboxymethly starch has shown fine properties of easier gelatinization,lower retrogradation,better freeze-thaw stability, strong anti-mycotic charicteristics,and higher charilty.The sodium chloride and calciuimon have shown better effects on their paste viscosity properities.

Key words: Potato Carboxymethly Paste property viscosity
