When heated, air expands to make it rise. 4 of 25 Acid Denature Acid is mixed with milk,meat or fish in order 5 of 25 Caramelise Sugar turns brown when heated. 6 of 25 Dextrinise Dry heat turns a starch brown. 7 of 25 Emulsify Two liquids are mixed-one is spread through the other in tiniy droplets. 8 of 25 Coagulate Proteins sets in the presence of heat or acid. 9 of 25 Ferment Yeast and bacteria break down carbohydrates and sugars 10 of 25 Enzymic Browning Enzymes in food react with oxygen and make foods turn brown. 11 of 25 Raising agent Added to make mixtures rise. 12 of 25 Gluten A protein formed when mixed with liquid present in wheat,barley & other cereal grains. 13 of 25 Gelation A liquid mixture that sets on chilling- 'gels' are liquid dispersed/trapped in soilds. 14 of 25 Forms A gas that is trapped in a liquid. 15 of 25 Polysaccharide A chain of many monosaccharide(sugar) units. 16 of 25 Denaturation Proteins change their structure when heated, agitated or mixed with acid. 17 of 25 Disaccharide 'Double sugar'- two molecules of sugar bonded together. 18 of 25 Monosaccharide A 'simple' single sugar molecule. 19 of 25 Maillard The browning reaction that takes place when aminio acids (proteins) are cooked with sugars. 20 of 25 Amino acid The building blocks of protein. 21 of 25 Conduction Where heat is transferred directly through soild materials, such as metals, and foods themselves. 22 of 25 Convection Where heat is transferred through a fluid (liquid or gas), such as water, stream, oil and air. 23 of 25 Radiation Heat rays directly heat and cook food. 24 of 25 Colloid A mixture of one substance dispersed throughout another. 25 of 25
