What is yeast-leavened bread?
Yeast-leavened products include most types of breads and rolls and such sweet-dough products as coffee cakes, raised doughnuts, and Danish pastries.

Slow-acting baking powders, containing phosphates, release part of their gas at room temperature and part when heated. Double-acting baking powder, the most widely used type, contains sodium aluminum sulfate and calcium acid phosphate and releases a small amount of gas when mixed and the balance when heated.
What is a leavening agent?
What is Leavening Agent? 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.
What are the different types of leavening agents?
Leavening agents that are used in the kitchen can be classified into the following categories, Biological (yeast) Chemical (baking powder, baking soda, baking ammonia) Mechanical (beating, whisking, creaming, sieving) Lamination. Combination of All.
What is the process of lamination?
The process lamination acts as raising procedure where the fat and dough is folded and rolled. When the moisture is incorporated in the fat and the dough also will vaporise during baking and give it the raising or lift.#N#This process is adapted by Indian cuisine like idles, dhoklas and utappam are steamed where heat helps to puff up the final product by vaporising the steam. Also in popcorn the corn is popped because of the moisture present in the corn and ultimately its volume is increased, and in choux pastry water vapour acts as raising agent which helps to cook in the oven.
What is the main fermenting agent for maltose?
Maltase helps convert maltose sugar into dextrose which will directly be fermented by yeast. Zymase is the most important fermenting agent which helps invert sugar and dextrose to break into carbon dioxide, a little amount of pure alcohol, and a small amount of glycerine, acetic acid, and little amount of lactic acid.
What are some examples of combination raising?
Danish pastry is the best example of a combination raising where we use yeast in the dough and fat is used by the lamination process. Vanilla buns, fruit cake are some examples of the combination process where the use of whisking, creaming, and chemical raising agent are used to finish the product.
Why does gas expand when baking?
When gas is entrapped into gluten structure or small air cell of the batter is developed because of the creaming action of fat. This structure expands with the production of gas and when baking the small parts of the gas gets absorbs by media itself.
What is Leavening Agent?
A leavening agent is an ingredient whose main function is the production, inclusion, and entrapment of gas (air or CO 2) in a dough or batter. One obvious function of leavening agents is the expansion of dough or batter to produce a volume increase which improves product texture and appearance.
Origin
The concept of leavening agents is as old as bread itself. Recorded evidence of leavened bread extends as far back as the ancient Egyptians and biblical times.
Function
In addition to gas production and baked product volume increase, leavening agents perform additional functions, such as:
Nutrition and health
Leavening agents do not perform a nutritional function in baked goods nor are they intended to enhance the nutritional value of the finished product. Given their nature, some leavening agents, like leavening acids, assume an extra addition of salts and sodium.
Regulation
The following table summarizes the basic regulation status of some leavening agents: 1,2,3

What is leavening agent?
Leavening agents can be categorized as: -Physical (mechanical) Water/steam. Air.
What is the role of air in leavening?
Air's important role in leavening: provides empty space for gases, like steam, to expand into. Without these empty spaces, leavening gases would have no place to go except out. Empty spaces can be: air bubbles or air cells in batters and doughs. gaps of space between layers in laminated doughs. Leavening Gasses.
What is the name of the gas that breaks down and gives off CO2?
An alkali; raises pH of batter/dough. Also called sodium bicarbonate or bicarbonate of soda. Breaks down and gives off CO2 gas in presence of water and heat. Not practical for leavening because of off-flavors, excessive browning, and yellow or green discoloration of crumb.
Why is acid added to baking soda?
Acid is added along with baking soda to aid in leavening, because high amounts of baking soda are needed to produce sufficient carbon dioxide for leavening, which cause discoloration and bad flavor. The added acid help the baking soda break down faster, creating enough carbon dioxide needed for leavening.
