The purpose of this study was to examine the physicochemical properties of biopolymer extracted from water chestnut in the presence of different ionic compounds (KCl, Na2HPO4 , CaCl2 ) at fixed starch (5%) and salts (1%) concentration. Experimental results showed that the presence of CaCl2 had a significant impact on swelling and thermal properties of water chestnut starch. The onset temperature of starch was found to be increased in the presence of KCl and CaCl2 , whereas a reverse trend was observed in case of Na2HPO4 . Furthermore, the addition of salts drastically reduced the swelling power and water absorption of water chestnut starch. The increase in peak viscosity and retrogradation was noticed after the addition of Na2HPO4 and CaCl2 , respectively.
