Study Notes
Raising Agents
Definition
- Substances used in baking to increase the volume and lighten the texture of baked goods.
Types of Raising Agents
-
Chemical Raising Agents
-
Baking Powder
- Contains an acid (e.g., cream of tartar) and a base (e.g., baking soda), activates with moisture and heat.
- Types: Single-acting (reacts once) and double-acting (reacts twice).
-
Baking Soda (Sodium Bicarbonate)
- Requires an acid (e.g., yogurt, vinegar) to activate.
-
Self-Raising Flour
- Pre-mixed flour with baking powder and salt.
-
Baking Powder
-
Biological Raising Agents
-
Yeast
- A living organism (fungi) that ferments sugars, producing carbon dioxide which causes dough to rise.
- Types: Fresh yeast, dry yeast, instant yeast.
-
Sourdough Starter
- A mixture of flour and water fermented with wild yeast and bacteria.
-
Yeast
-
Mechanical Raising Agents
-
Air Incorporation
- Achieved through methods like creaming butter and sugar, whisking eggs, or folding in ingredients.
-
Steam
- Generated from moisture in the batter when heated (e.g., in choux pastry).
-
Air Incorporation
Functions
- Create gas bubbles, leading to a light and airy texture.
- Contribute to the overall flavor and structure of baked goods.
Factors Affecting Raising Agents
- Temperature: Affects the activity of yeast and chemical reactions.
- Acidity: Influences the effectiveness of baking soda.
- Moisture: Essential for activating most raising agents.
- Time: Allowing dough or batter to rest can enhance flavor and texture.
Common Uses
- Cakes, bread, muffins, pastries, and cookies.
Storage
- Keep chemical raising agents in a cool, dry place; check expiration dates.
- Yeast should be stored in the refrigerator for longer shelf life.
