What You Need to Know
During heating to 60‑70 °C, starch granules gelatinize, releasing amylose which forms hydrogen bonds with water and neighboring chains. Upon cooling, retrogradation of amylose and amylopectin establishes a three‑dimensional gel network, while sugars act as plasticizers lowering the gelatinization temperature.
