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

Heat Transfer (cont.)
• Radiation - transfer of heat through waves that move from the heat source to the food.– Infrared cooking– Microwave ovens

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– Sugars caramelize– Carryover baking– Staling

• The five primary Tastes are: – Sweet– Sour– Salty – Bitter – Umami

Science of Taste
• Chewing releases flavor compounds in food• Taste buds on the tongue detect taste and flavor
compounds• Aromas and odor compounds reach olfactory bulb
through internal and external nostrils

Effects on Flavor Perception
• TEMPERATURE. Foods at warm temperatures offer the strongest tastes.
• CONSISTENCY of the product• PRESENCE OF CONTRASTING TASTES• PRESENCE OF FATS• COLOR

Compromises to Taste Perception
• Sense of taste can be challenged by factor’s beyond one’s control.– Age– Health– Smoking
