WebJan 12, 2024 · This was related to the barriers of starch gelatinization and starch hydrolysis, caused by the enwrapping of the starch granules with a complete protein matrix. Choi, Woo, Ko, and Moon also found similar results. They used a confocal laser scanning microscope to examine the microstructure of waxy sorghum flour. 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.
