There are 4 different raising agents;
1.1. AAir
2.2. BBread Soda
3.3. BBaking Powder
4.4. YYeast
THINK ABBY!!!!

1. Air
• In all baked foods, it is important to get lots of air into the mixture
• Air expands when heated and makes the food light

• Air is introduced into a mixture by; 1. Sieving the flour 2. Rubbing fat into flour, high over the bowl 3. Creaming/beating fat and sugar 4. Whisking eggs and sugar

Chemical Raising Agents
Bread Soda Baking Powder
Equation to show how Chemical Raising Agents Work!!!!
Alkali + Acid = Carbon DioxideAlkali + Acid = Carbon Dioxide

2. Bread Soda
• Bread soda is alkali • When mixed with buttermilk (acid) and a liquid it
makes CARBON DIOXIDE • The CARBON DIOXIDE expands and rises when
heated, raising the dough

3. Baking Powder
• Baking powder is a mixture of bread soda and an acid
• When moistened by eggs or milk CARBON DIOXIDE is produced
• The CARBON DIOXIDE expands and rises when heated, raising the dough

4. Yeast
• Yeast is a micro organism • It produces CARBON DIOXIDE in the dough • The CARBON DIOXIDE expands and rises when
heated, raising the dough• Used in commercial breads
