A decreased enthalpy advocates a lesser degree of organization in the granule which in turn lowers the crystal stability (Chiotelli & Le Meste, 2002). The peak high index (PHI) of gel ranged from 1.23 to 3.93%. PHI is an indicator which represents the shape of the endotherm. An endotherm which is narrow and tall indicates an increased peak whereas the short structure of the endotherm represents a low PHI irrespective of the energy involved in the transition (Krueger, Knutson, Inglett, & Walker, 1987). Hence, the variation in thermal properties of raw and blanched flours with respect to the methods of drying could be attributed to the differ- ence in the size of starch granule and its shape, length of amylo- pectin polymer chain, size and stability of crystalline areas.
