The addition of three kinds of polysaccharides could
increase the hardness of rice starch–polysaccharides
mixed gel, low concentration (0.3%) could increase
the hardness more signiWcantly, the konjac glucomannan
could not increase the hardness notably. The three varieties of rice starch had diVerent hardness of the mixed gel,
the indica rice starch was always the largest and the
sticky rice starch had the lowest value. The hardness of
the rice starch–gellan mixed gel mainly came from the
network structure of gelatin polysaccharides rather than
the retrogradation of amylose.
