Physical modification altered the setback viscosity of corn starch. HMT, AHT, and OPT starch havea significantly lower setback viscosity compared to native corn starch, whereas MHT starch wassignificantly higher. The decrease in setback viscosity of HMT starch might be due to an increase inbond strength in the amorphous region.[61] The amylose molecules in native corn starch weredispersed more randomly than the modified corn starch so it can be oriented to form aggregatesand gel formations.[
