2. Permanent structural change of the protein molecules in food.
This can occur by application of heat. Hold of shape with cooking of eggs.
This can occur with mechanical action. Beating egg whites or cream.
DENATURATION
Permanent structural change of the protein molecules in food.
This can occur by the addition of acids. Adding lemon juice to meats.

3. DEXTRINISATION
The process that occurs when starch is exposed to dry heat; the starch is broken down to dextrin resulting in a change in colour to golden brown.
Browning of Bread when baking.

4. GELATINISATION Adding flour to Bechamel Sauce in cooking to thicken.
The process that occurs where starch granules absorb liquid in the presence of heat and thicken the liquid, forming a gel.

5. MAILLARD REACTION Grilling, frying, roasting of meat.
The reaction that occurs when sugar or starch and a protein are present in a food and dry heat is applied, producing a golden brown colour.
Baking, frying of bread.

6. ENZYMATIC BROWNING Browning Bananas, due to ripening and aging.
Enzymes that naturally occur in food and causing fruit to brown and convert starch to sugar which sweetens and softens fruit.
Cutting Apple, browning due to exposure to oxygen.

7. CARAMELISATION
The process that sugars undergo when heated to high temperatures to develop a golden brown colour.
Heating of sugar causes it to melt and brown

8. EMULSIFICATION
The ability of fat or oil to be equally dispersed or suspended throughout a liquid.
The use of egg yolk fat (Lecithin) used with oil to create mayonnaise.

9. AERATION Beating of eggs
Beating of egg whites
AERATION
