Leavening Agents: Physical and Chemical Reactions BAKING

The exact measurement of leavening agents is crucial to the success of baked products Even a small change in the amount of a leavening agent can impact the quality of baked goods The gases and the process of fermentation caused by leavening agents lighten batter and dough



Background: Baking Techniques

Leavening Agents Leavening agents make batters and doughs rise during baking giving them their porous light tender texture Baking powder (a mixture of baking soda and acid) forms carbon dioxide in combination with liquids The bubbles cause the batter to expand during resting or baking The three leavening agents are air steam and carbon

LEAVENING AGENTS—Leavening agents are sub-stances that help bread dough rise Biscuits are quick breads made with leavening agents that react quickly These breads can be baked at once and do not require a rising period before baking Low-sodium baking powder may be purchased if anyone in the family is on a low-sodium diet The leav-

What is a leavening agent?

    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. Leavening of baked foods with air is achieved by vigorous mixing that incorporates air bubbles, producing foam.

What is the function of leavening agent in dough?

    Leavening agent or yeast converts sugars present in dough to carbon dioxide and derive energy from this reaction. Due to this, yeast cells grow and dough also expands. When such dough is baked then air pockets formed due to carbon dioxide will give soft and spongy texture to bread and idli. What helps in the rise of bread or dosa dough *?

Which of the following is responsible for the leavening action in baked goods?

    Carbon dioxide gas is most often responsible for the leavening action in baked goods and can be produced by biological agents like yeast, or chemical agents such as baking soda and baking powder. 18 Biological Leaveners Yeast Is a living organism that ferments sugars for energy.

What is the best leavening agent for cake?

    Baking soda as we talked about reacts immediately to acidic elements and gives immediate leavening effect. The baking powder keeps reacting with the heat to give a leavening boost while the baked goods are in the oven. A combination of both these leavening agents gives the best leavening for most cake recipes.

Leavening Agents

How Baking Works

Words, Phrases, and Concepts

Leaveners

Air bubbles/air cells

Retarded dough

Pre-ferment

Antimicrobial agents

Osmotolerant yeast

Bench tolerance

Acid salt

Single-acting and

double-acting baking powders

Fast-acting and slow-

acting baking powders

Process of Leavening

Leavening agents:

Also called leaveners.

Allow baked goods to rise.

Leavened baked goods: are lighter in

density and higher in volume than batter/dough.

Leavening: starts in mixing bowl.

Process of Leavening

For baked goods to rise properly:

1.Air bubbles must be added to batter/dough.

2.Gases (carbon dioxide, steam) must form

and expand from heat of oven.

3.Still-flexible cell walls must stretch from

pressure of expanding gases.

4.Structure builders in cell walls must dry out

and set, defining final volume and shape.

Once cell walls set, leavening ceases; pressure

builds, breaking cell walls; gases escape.

Process of Leavening

Timing is important.

For best volume, gas expansion must occur

while cell walls are stretchy and flexible.

With yeast-raised doughs, this occurs during bulk

fermentation, proofing, and early stages of baking.

With cakes, muffins, pastries, this occurs as

proteins coagulate and starches gelatinize during baking.

Leavening Gases

Leavening agents can be categorized as:

Physical (mechanical)

Water/steam

Air

Biological (organic)

Yeast fermentation

Chemical

Baking soda + acid

Baking powder

Baking ammonia

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)

Leavening Gases

1. Steam

Gaseous form of water.

All baked goods rely on steam for some

leavening:

Because all baked goods contain water or another

liquid (milk, eggs, etc.).

Sponge cakes, popovers, choux pastry rely heavily

on steam for leavening.

Steam is an extremely powerful leavener: it

occupies over 1,600 times more space than water.

Leavening Gases

1. Steam

Very hot ovens often maximize leavening

from steam.

Leavening Gases

1. Steam is sometimes injected into oven

during early stages of bread baking:

Delays setting of crust.

Allows bread to rise higher.

Results in crisper, glossier, thinner crust.

Leavening Gases

2. Air

All baked goods rely on air for leavening.

This is because all batters and doughs contain air trapped during mixing, stirring, whipping, sifting, folding, etc.

Sponge cakes and angel food cake rely heavily on

air for leavening: they contain lots of air bubbles whipped into egg whites.

Laminated doughs and flaky pastries rely heavily

on air for leavening: they contain large gaps of air, when chunks of fat melt.

Leavening Gases

2. Air itself does not expand much during

baking.

Because it is already a gas.
