Single (SHMT) and dual heat-moisture treatment (DHMT) were used in modified starch. SHMT and DHMT affected the property of sodium alginate-normal cornstarch (AG-NCS). Treated AG-NCS processed the property of anti-shearing and anti-retrogradation. SHMT had the most remarkable effect on pasting property of AG-NCS. Among all the samples, AG-NCS after DHMT-20 showed the lowest RC value.
