The endothermic peak in the DSC thermogram is associated to the starch gelatinization transition process. Starch-composition, fine structure and architecture.
In general, the average temperature and enthalpy of gelatinization decreased when the removed surface increased, showing disorganization or “weakening” of the granule structure. Journal of Applied Physics 19, Inner structure of plantain starch granules by surface chemical gelatinization: Maize starch; gelatinization enthalpy. This knowledege about starch gelatinization is very useful for optimizing industrial process derivate of it. This study demonstrates that the parameters associated to the observation method, in the DSC analysis, are influential in the determination of the maize starch gelatinization.
Initial phase of process and range in which it occurs is governed mainly by starch concentration in the solution, and the botanical source. The variation also depends of rate which transformation is made.

Functional properties of oat starches and relationships among functional and structural characteristics. American Association of Cereal Chemists, St. Preparation and food applications of physically modified starches.
Food Chemistry 3a ed. Mechanism of starch gelatinization in neutral salt solutions. Knowledge of the organization of plantain starch components amylose and amylopectinsupport to explain the physicochemical, functional and digestibility characteristics, as well as its reactivity when geltinizacion plantain starch is enzymatic and chemical modified. However, surface gelatinization did not affect the X-ray diffraction pattern and the crystallinity level.
Internal structure of normal maize starch granules revealed by chemical surface gelatinization. Amylolytic enzymes and producys derivad from starch: A comparison of potato and cassava starches. Results indicate that the amount of water has influence over the enthalpy transition; however the peak temperature Tp remains invariable.
