Reduced peak viscosity and increased pasting temperature after HMT were found. The To, Tp and Tc of HMT samples were higher than those of native counterparts, both for wheat starch and wheat flour. HMT significantly changed the crystal structure and crystal pattern. The higher moisture contents of treatment would produce the higher resistant starch (RS) con- tent. In addition, the RDS content of native and HMT wheat starch were higher than those of wheat flour. The results may have po- tential application in preparation of noodles, cookies and snacks with lower RDS.
