All the starch samples showed typical A-type crystalline pattern with high intensity peaks at Bragg’s angle (2θ) about 15.25°, 18.11°, and 23.33°. The diffraction pattern of corn starches was similar to the other cereal starches indicating its semi-crystalline nature.
WebNational Center for Biotechnology Information WebStarch gelatinization is a process of breaking down of intermolecular bonds of starch molecules in the presence of water and heat, allowing the hydrogen bonding sites (the hydroxyl hydrogen and oxygen) to engage more water. This irreversibly dissolves the starch granule in water. Water does act as a plasticizer.. Three main processes happen to the …
