Cereal Chemistry 71, Food Polysaccharides and their Applications Stephen, M. In general, the average temperature and enthalpy of gelatinization decreased when the removed surface increased, showing disorganization or “weakening” of the granule structure.
In this way, the transition peak temperature, gelatinization enthalpy, and range of temperature are parameters that have to be considered when the moisture of sample and heating rate are changed with a homogenous grain size. 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. The thermal behavior of corn starch Sigma Aldrich was studied by differential scanning calorimetry DSC.
Physicochemical characteristics of starches from unripe fruits of mango and banana. Journal of Agricultural and Food Chemistry 59, Journal of Cereal Science 39, Results indicate that the amount of water has influence over the enthalpy transition; however the peak temperature Tp remains invariable.
