Leavening agents

Leavening agents are substances that are added to food to create the desired texture or volume of food by causing the release of various gases , most commonly carbon dioxide. These gases increase the volume of the dough. Without leavening agents, our bread would be flat and crunchy. For example, baking soda adds fluffiness to baked goods, while potassium bicarbonate is used to create fizz in drinks.

The most common leavening agents include soda, baking powder and leavening tablets. Yeast is also used a lot, but it is not considered an additive.

Leavening agents are also used in the production of foams such as bath foams or shaving foams. These substances increase the volume of the foam and improve its consistency .

What leavening agents do we have?

What types of cypresses are there?

  • Biological fermenters: These fermenters help in the fermentation of sugars to form carbon dioxide. Yeast is the most widely used biological leavening agent (yeast, bread yeast or other variant of yeast). Yeast is responsible for the fermentation process.
  • Chemical leavening agents: We know these leavening agents as leavening agents, which are marked with E-numbers in the food industry. They work by releasing carbon dioxide in the dough, which is triggered by moisture or heat. The air bubbles expand as a result of the carbon dioxide and the pastry rises. Chemical leavening agents contain, for example, baking powder or baking soda.

How do leavening agents work?

Cereals contain glutenin and gliadin as the main proteins. Of all cereals, wheat contains the highest amount of these proteins. Wheat flour dough then contains both glutenin and gliadin. When these proteins of different properties are mixed with water, they hydrate and form a new protein called gluten .

The elasticity and strength of the dough is due to glutenin and gliadin, which give gluten adhesive properties. The gluten molecules arrange themselves to form a continuous network that is stiff and elastic. Raising agents form thousands of bubbles in the dough , which cause it to rise. The dough rises due to the action of leavening agents and the gluten has the ability to expand. The kneaders release gases from the flour, creating air pockets and making the dough light and fluffy . They help in the expansion of the dough by releasing gases in the flour mixture, resulting in baked products with a porous structure.

If the bubbles burst and the gas escapes, there will be no rise. Therefore, these gases are necessary to maintain the product until the product solidifies and retains its shape. The elasticity of the dough is therefore needed so that the bubbles expand without bursting and the gas remains trapped in the bubbles long enough. So eventually, when the gas finally escapes, these air pockets retain their shape instead of collapsing. The size of the air pockets determines the texture of your baked goods. Small air pockets result in a smooth texture like cakes, while larger ones lead to a coarse texture like bread. Don’t forget to try our excellent recipes for white flour pastries 5 different ways!
