Received: 21 April 2012; in revised form: 6 May 2012 / Accepted: 18 May 2012 / Published: 29 May 2012 Abstract: Retrograded starch (RS ) was produced from indica rice starch with three kinds of 3 gums (konjac glucomannan, KGM; carrageenan, CA, USA; and gellan, GA, USA) by autoclaving, respectively, and the effect of the gums on the retrogradation behavior of starch was estimated. The influences of polysaccharide concentration, sodium chloride concentration, autoclaving time, refrigerated time, and pH value on RS3 formation were discussed. Except for sodium chloride’s persistent restraint on RS , the others all forced RS yields higher at 3 3 first,
