Yeast.
Only if they have another leavening agent such as yeast, baking soda, or cream of tartar.
The function of leavening agents is to cause the baked goods (breads, cakes, etc.) to rise. There are different types of leavening agents, such as yeast, baking powder and baking soda. Eggs are also sometimes used as a leavening agent, especially in some pound cake recipes. Without leavening, the baked goods will not only be flat, but won't taste as good, either.
Baking soda is used in food as a leavening agent, which helps baked goods rise and become light and fluffy. It reacts with acidic ingredients in the recipe to create carbon dioxide gas, which causes the dough or batter to expand. Additionally, it can help neutralize acidic flavors and contribute to a golden brown crust on baked goods.
Aluminum phosphate is commonly used as a leavening agent in baking powder, which is used in a variety of baked goods such as cakes, cookies, and breads.
Baking soda is a leavening agent that helps baked goods rise by producing carbon dioxide gas when it reacts with an acid (such as vinegar, lemon juice, or buttermilk) in the recipe. It also contributes to the browning and crisping of certain baked goods.
Baking soda is a leavening agent that helps baked goods rise by producing carbon dioxide gas when combined with an acid (such as buttermilk, vinegar, or citrus juice) and liquid. It also helps baked goods brown more evenly and develop a characteristic texture.
Baking soda is neither a nitrate nor a phosphate. It is a compound known as sodium bicarbonate, which is used in baking as a leavening agent to help baked goods rise.
If you mean leavening ingredients, they are used to make baked goods rise. Baking powder, baking soda, and yeast are all leavening agents.
It's when you use more than one type of levening agent. Like baking powder and baking soda. Each one causes the baked goods to rise in a different way.
Baking soda is considered a mild base (weakly alkaline) rather than a strong base. It reacts with acids to neutralize them and can also act as a leavening agent in baked goods.
Gluten is a binding agent. It keeps baked goods from falling apart and being crumbly.
