Study Notes
Leavening Agents
- Leavening agents are the chemicals or organisms that cause baked goods to rise.
- They work by producing gas, which expands and creates air pockets within the dough or batter.
- The size and shape of these air pockets affect the texture of the final product.
Types of Leavening Agents
- There are three main types: biological, chemical, and steam.
Biological Leavening Agents
- Yeast is a type of single-celled fungus that consumes sugar and produces carbon dioxide and alcohol as byproducts.
- Active Dry Yeast is a granulated yeast that needs to be activated in warm water before use.
- Instant Dry Yeast is also granulated, but it can be mixed directly into flour.
- Fresh Yeast is sold in blocks and can be used directly in dough or dissolved in water.
Chemical Leavening Agents
- Baking soda is a powdered base that reacts with acidic ingredients, releasing carbon dioxide gas.
- Baking powder contains baking soda, an acidic component, and a drying agent. It reacts when moistened.
Yeast
- Yeast is essential for producing beer, wine, and bread.
- The process of yeast fermentation leads to the production of CO2 gas, which causes dough to rise.
- Yeast provides flavor to baked goods.
Baking Soda
- Baking soda requires an acidic ingredient to activate it.
- The reaction is quick, resulting in "quick breads" like muffins.
Baking Powder
- Baking powder contains its own acid, so it does not require additional acidic ingredients.
- The reaction is also quick, similar to baking soda.
Steam
- Steam acts as a leavening agent in baked goods, but it is not the primary leavening agent.
- In products like puff pastry, steam trapped within layers of dough causes it to rise.
- Its ability to create air pockets is reliant on the structure of the dough.
Gluten
- Gluten is a protein found in wheat flour that gives dough its elasticity.
- The gas produced by leavening agents gets trapped in the gluten network, causing the dough to rise.
Dough Elasticity
- The elasticity of the dough allows it to stretch and trap the gas from the leavening agents.
- This prevents the gas from escaping and ensures the dough rises properly.
- Dough elasticity is affected by kneading and the type of flour used.
Bread Texture
- The size of the air pockets formed during baking affects the texture of the final product.
- Small air pockets create a smooth texture, like in cakes.
- Larger air pockets create a coarser texture, like in crusty bread.
