Besides, it was probably due to the restriction of water penetration into the granules by the new superficial protein layer formed by HMT, thus retarding the granule swelling. Enthalpy change of HMT starch and flour samples decreased
Higher moisture levels of treatment showed larger reductions in DH of the first peak. Enthalpy change reflects the melting of imperfect amylopectin-based crystals, with potential contributions from crystal-packing and helix melting enthalpies
