What You Need to Know
During heating, water penetrates the granule, disrupting its crystalline structure. Amylose leaches out and interacts with amylopectin, increasing viscosity and forming a gel network. The extent of gelatinization depends on temperature, time, water-to-starch ratio, and shear.
The Science
Primary Reaction
Starch granules absorb water, swell, lose crystallinity, and form a viscous gel network.
