1 Functions of Water

2 Functions of Water Water has two functions in food: Heat medium
Universal solvent B Functions of Water

3 Heat Medium Water transfers heat to food Heat is transferred through:
Steam (gas) Boiling (liquid) Heat is transferred through: Conduction -- rapid movement of molecules in food Convection -- circulation of hot and cold molecules Forced or natural Radiation B Functions of Water

4 Universal Solvent Water is a universal solvent because it can dissolve many substances Types of water solutions include: Gas in water Liquid in water Solid in water Fats and oils do not dissolve in water B Functions of Water

5 Universal Solvent Gas-in-Water Solutions Gas dissolved in water
Carbon dioxide carbonated beverages Oxygen cold and hot water B Functions of Water

6 Universal Solvent Liquid-in-Water Solutions
Liquid other than water dissolved in water Vinegar Ethanol B Functions of Water

7 Universal Solvent Solid-in-Water Solutions
A solid substance dissolved in water Common solid-in-water solutions: Salt in water Sugar in water B Functions of Water
