Principles of Baking
• This chapter introduces the student to the scientific basis
for what takes place in the bakeshop.
• Concepts and vocabulary presented here are used and
expanded upon throughout the text.
• Understanding the science of mixing fat, flour and water
to make a finished product makes for a well-rounded
professional.

Mixing
Once ingredients are measured, they must be
MIXED
Mixing accomplishes:
• Even distribution of ingredients
• Breakdown of fats and liquids, causing them to
emulsify
• Activation of the proteins in wheat flour causing
formation of gluten
• Incorporation of air (aeration) into dough.

Importance of Moisture
• Moisture dissolves ingredients, helps hydrate and
activates compounds in dough
• Doughs have low water content.
– Yeast bread dough, cookie dough, pie dough.
• Batters generally contain more liquids, fat and
sugar than doughs.
– cake batter, muffin batter and pancake batter.

Heat Transfer
• Conduction - movement of heat from one item to

– Pan placed over burner
• Convection - transfer of heat through a fluid,
which may be liquid or gas.
– Hot air circulating in oven

Baking and Cooking Methods
• Dry-heat cooking uses air or fat and is the
principal method to cook:
– batter
– dough
• Moist heat uses water or steam for cooking:
– fruits
– tenderizing foods
– reducing liquids

The Baking Process
• Batters and dough pass through 9 stages during the baking
process:
–

Gasses form
Gasses are trapped
Starches gelatinize
Proteins coagulate
Fats melt
Water evaporates

• PRESENCE OF CONTRASTING TASTES
• PRESENCE OF FATS
• COLOR
