When cornstarch is added to a liquid and heated, what happens to thicken the mixture?

Options:

Starch granules swell and gelatinize
Proteins coagulate and set
Fats emulsify and stabilize
Sugars caramelize and darken

Correct answer: Starch granules swell and gelatinize

Explanation: Cornstarch thickens by starch gelatinization: granules absorb water, swell, and leach amylose when heated, typically between about 62–72°C, forming a glossy viscous gel.
