Fig. 2 shows the endothermic curves of the rice varieties. INIAP
17, INIAP 16, F09 and F50 showed a shoulder peak; like it has been
reported in Thai rice variety due to amylopectin structure
composed by two different molecular structures (Kim et al., 2010).
No significant correlation was observed between gelatinization
parameters and hydration properties, neither with apparent
amylose content. Presumably, the presence of protein and lipid in
rice flour also influence the gelatinization process, and affect the
water-starch bonding
