Leavening agent, substance causing expansion of doughs and batters by the release of gases within such mixtures, producing baked products with porous structure. Such agents include air, steam, yeast, baking powder, and baking soda. Learn about the types of leavening agents with this article.
In cooking, a leavening agent (/ ˈ l ɛ v ən ɪ ŋ /) or raising agent, also called a leaven (/ ˈ l ɛ v ən /) or leavener, is any one of a number of substances used in doughs and batters that cause a foaming action (gas bubbles) that lightens and softens the mixture.
Biological leavening—Biological leavening is the process of using living organisms that characteristically release carbon dioxide to leaven things like doughs and batters, for example. Typical biological leaveners include sourdough starters, yogurt, buttermilk, and, more commonly, yeast.
20 Απρ 2021 · Leavening agents are the agents that increase the surface area of the dough or batter by creating gas bubbles in the dough or batter. When the gas bubbles start to expand during baking and increase the volume of the product and give a desirable porous structure.
8 Αυγ 2020 · But the simplest way to think of it is that the leavening agent produces the gas, and the gas causes the dough or batter to rise. There are three main types of leavening agents: biological, chemical, and steam.
10 Μαΐ 2022 · The word leavening in the baking trade is used to describe the source of gas that makes a dough or batter expand in the presence of moisture and heat. Leavening agents are available in different forms, from yeast (the organic leavener) to chemical, mechanical, and physical leaveners.
Leavening Gases These leavening agents generate three main leavening gases: 1. Steam 2. Air 3. Carbon dioxide Other liquids and gases that leaven: –Alcohol (from yeast fermentation, flavor extracts) –Ammonia (from baking ammonia)
