What You Need to Know
During heating, water evaporates around 100 °C and milk solids undergo Maillard reactions between lactose and whey proteins, forming melanoidins that give ghee its nutty flavor and antioxidant properties. The fat is extracted at temperatures near 170 °C, and cooling allows the clear fat to separate from browned solids.
