Study Notes
Heating Starch Granules
- Starch granules undergo significant changes when heated in a moist environment.
- Initial process involves the absorption of water, leading to granule swelling.
- Swelling is caused by water molecules penetrating the granule structure.
- As granules absorb water, their organized structure begins to disrupt.
- The organization of starch granules is essential for their functionality in food applications.
- Disruption affects the physical properties of starch, influencing texture and consistency in food products.
- Understanding these changes is crucial for applications in cooking and food production.
