The Science of Bread

What is bread?

Bread is made up of 4 key components this is more about bread that rises).

1. Flour

2. Water

3. Yeast

4. Salt

Flour

Flour is the structure. which are made from glutenin (strength) and gliadin (stretch). When you add water and mix, the protein hydrates, and link together and make gluten, This creates a viscoelastic network. Think of net that can stretch, this net helps trap gas.

Strong gluten network -> Chewy Bread ( Bagels)

Weak Gluten -> Soft bread (Brioche)

Water

Water is the kickstarter, and it does a whole bunch of things like:

• hydrates the protein

• dissolve salt + sugar

• activate yeast

• allows enzymes to work

Hydration Levels

Yeast

Yeast eats sugar and produces gas (CO2 + alcohol) which helps the bread rise! This process is called fermentation, which helps create flavor, aroma, and better texture. A longer fermentation = deeper flavor.

Salt

Salt is small but mighty, it control everything.

• strengthen gluten

• slows yeast

• improve flavor

Without salt, dough is sticky, rises too fast, and taste bland. So yes, that pinch of salt really does matter!

Kneading

Kneading is needed activate water with all the other ingredients.

Kneading aligns gluten, strengthen structure, and creates elasticity which allows the dough to trap gas and expand without tearing.

Fermentation Stages

Bread usually ferments twice:

1. Bulk Fermentation (First Rise)

   • yeast produce gas

   • gluten relaxes

   • flavor develops

   Which the dough becomes airy and extensible

2. Proofing (Second Rise)

   After shaping:

   • dough rises again

   • structure is refine

     This is what determines the final shape and crumb.

The Oven Spring

This is most important part! When the dough his the oven:

1. Gas Expands

2. Yeast Burst

3.
