Use of raising agents

What are raising agents?

• Substances that help flour rise.

• Usually used in making cakes, buns or bread to make them light, tasty and easy to digest.

• Types include air, steam and chemical raising agents.

Principles:

Air expands when heated, thus pushing the flour mixture up and making it light in texture.

We can incorporate air into the flour mixture by:

Principles:

When the mixture is heated, the moisture changes to steam and its volume can increase up to 1600 times slowly. This can help the mixture rise.

Chemical raising agents

Principles:• When a chemical raising

agent is mixed with moisture and heated, it produces carbon dioxide.

• Carbon dioxide expands when heated and makes the flour mixture rise.

In making flour mixture, air is incorporated while moisture and chemical raising agents are added.

When heated, different raising agents expand and push up the mixture, making it rise.

In further cooking, the gluten around the gas bubbles hardens. This fixes the shape of the mixture.

Tips for whisking

Keep eggs at the room temperature.

If the weather is cool, put the mixing bowl over a pan of hot water when whisking.

Besides electric mixer, we may whisk either with a balloon whisk or a rotary whisk.
