Fundamentals of Bread Baking
4 Basic Bread Dough Ingredients
WHEAT FLOUR Backbone & Structure Absorbing agent
SALT Regulates fermentation Strengthens gluten Imparts flavor Prevents bacteria growth
YEAST Fermentation & aeration
WATER Controls dough temperature Forms gluten.
Other Bread Dough Ingredients
Added to change the texture or characteristics of the bread. SUGAR
Tenderizes Adds sweetness Crust color
SHORTENING Shortens gluten strands Tenderizes Improves crust and grain
DMS (Dry Milk Solids) Crust color Flavor Adds nutritional value Improves texture
Basic Yeast Doughs
HARD / LEAN Thin to Thick Crispy Crust
0% to 2% added fats or sugars
SOFT / MEDIUM Softer crust & crumb
2% to 8% added fats or sugars
SWEET / RICH Very soft & cake like
8% to 20% or higher added fats or sugars
Flour
Wheat Flour
Gluten
Three Parts of a Wheat Kernel
Bran – 13% Hard outer portion of the wheat berry Fiber and B vitamins
Germ – 2% Fatty portion of the wheat berry Vitamin E Seed portion
Endosperm – 85% Contains starch particles, carbohydrates,
and gluten forming proteins
Classifications of Wheat Flours
1. Hard Flour 11-14% High protein content Less starch Creamy color Does not pack Dusts well Granular to the feel Makes the best bread
Bread Flour, High Gluten Flour
2. Soft Flour 6-10% Low protein content Higher starch content Whiter in color Packs easily Does not dust well Makes the best cakes and
pastries
Cake Flour, Pastry Flour
Gluten
Protein found in wheat flour
Two Components of Gluten
1. Glutenin Provides strength & structure Retains gasses
2. Gliadin Provides elasticity and
stretchability
When wheat flour is combined with liquid, gluten is formed.
The components of gluten are developed thru a means of mechanical or hand mixing.
Gluten: Wheat Protein
Only found in large amounts in Wheat.
Forms tough, rubbery and elastic dough if mixed enough and well developed.
Developed more fully in yeast doughs.
Lesser amount in quick breads & pastries.
Yeast
Yeast Fermentation
Compressed Yeast: Wet Yeast
Tan in color, fresh smell & firm.
Storage: 38°F - 40°F Up to 4 weeks.
Deteriorates rapidly at room
temperature.
70% water content
Protein, fat & ash
Dry Active Yeast
Dry granulated form.
Same strain as compressed.
Moisture content: 7.5% to 8.5%
Less protein content.
Use 50% less of Wet: 1# Wet = 8 oz. Dry
Rehydrate: water temp. 105° - 110°F
Instant Yeast: SAF
More potent
Longer shelf life
Less than 5% moisture
Use 1/3 of wet (100% wet=33% instant)
Less sensitive to temperatures
Usually add to dry ingredients
Less Taste & aroma
Conditions for Yeast Fermentation
FOOD - WARMTH - MOISTUREYeast + Sugar = Co2 and Ethyl Alcohol
FOOD: Starches, carbohydrates & sugars must reduce to simple sugars (glucose and levulose)
WARMTH: Friction, Water, Room & Flour
MOISTURE: Dough covered at all times & proper amount of water
to the formula.
Yeast Fermentation Yeast converts sugar into Co2 & Alcohol.
Cell Division: “BUDDING”.
Co2 is trapped in the Gluten. Dough rises.
Starts at the mixer and end in the oven.
Dough thrive at: 78 – 82F
Thermal Death Point (T.D.P.) 138˚F Fermentation ceases.
Alcohol evaporates in the oven.
TEN STEPS OF BREAD MAKING Scaling Mixing Floor Fermentation Divide Round Bench Rest Shape Pan Final Proof Bake
Step 1: Scaling
Proper measurement of all ingredients equals accurate & successful products.
Dry: Baker’s scale
Wet: Volume measure
Pint to pound
Syrups: Baker’s Scale
The 240 FactorDetermining water temperature
Ideal dough Temperature: 80f
Room: 78˚F Friction Factor: 240Flour: 68˚F Variable: -176Friction:30˚F Water Temp: 64˚F 176˚F
Dough mixed on 2nd speed: 20-30F
Step 2: Mixing
Three Objectives1. Uniform mixture of all ingredients
2. Gluten Development
3. Initiate fermentation through yeast nourishment
Straight Dough Method
Simplest form of dough mixing
All ingredients are mixed in one operation
Scale ingredients in a STRAIGHT line:
Water Yeast Dry Ingredients
Straight Dough Method
Scale Ingredients Mise en Place
Tare scale
Scale all ingredients
240 Factor water
Liquids: volume
Dry: scale
Accuracy is important
Straight Dough Method
Dissolve yeast and water in bowl.
Add flour to water
Add salt to the flour. Do not add salt to water &
yeast.
Straight Dough Method
Mix on first speed. Mix till incorporated.
Mix till clean-up. Add fats slowly.
Straight Dough Method
Develop the gluten on 2nd speed.
Tacky & smooth.
Cover dough & keep away from drafts.
Floor ferment till double in volume.
Straight Dough Method
Straight Dough Procedure
Mise en place all ingredients & equipment. Soften the yeast in the water. Combine the remaining ingredients in the bowl. Mix to
a smooth developed dough. CLEAN-UP: Flour absorbed into water. 1st. Speed: achieve CLEAN-UP. 2nd. Speed: Develop gluten Smooth & Elastic. Well developed.
Step 3: Floor Fermentation
First PROOFING STAGE
Dough MUST be covered
Should double in size
Temperature affects fermentation time
“PUNCH” down dough: Expels Co2 Evens dough temp
Floor Fermentation; Punching
Large amount of Co2.
Yeast can’t thrive in “OLD” Co2.
Expel out the “OLD”.
Make room for the “NEW” Co2.
Evens temperature.
Strengthens gluten strands.
Step 4: Dividing
Must be done quickly & as accurately as possible.
Always use Dough Cutter or Bench Scrapper.
Never rip dough, causes
“BLEEDING”
Step 5: Rounding
Gather dough into a tight but smooth mass
Do not over work
Place dough pieces in a floured bench box
Keep covered
F.I.F.O.
Step 6: Bench Rest; Intermediate proofing Stage
2nd PROOFING STAGE
Short Resting Period; 15-20 minutes
Keep covered on work table or in dough box
Relaxes Gluten
Double in size
Check for over fermentation.
Step 7: Shaping
After proper resting dough must be shaped quickly as possible
Punch out old Co2
Seams must be sealed straight & tight
Seams must be placed on the bottom of any molded item
Step 8: Panning
Prepare accordingly to the style of bread
Egg wash soft doughsoft dough & place on parchment paper
Water wash hard doughhard dough & place on surface with cornmeal
Step 9: Final Proof
Achieves maximum fermentation
Warm & Humid environment: Proof Box
Temperature: 80˚-95˚F
Humidity: 80-90%
Double in volume, light & airy to the touch
Step 10: Baking
Dough changes into an appetizing & desirable product.
Baking times & temperature depend on Types of dough size of units richness of dough crust color desired weather
Effects of Steam Injection on Yeast Raised Doughs
Oven Spring: Blooming or blossoming of the dough in the first few minutes of the bake
Moisture is needed in the oven to achieve GOODGOOD oven spring
Low moisture steam: 15-20 psi. 5-10 min
Develops excellent crust color
Achieves excellent thin crispy crust
Too much steam: Soggy & chewy crust
Steps 11 & 12: Cooling & Storage
Carry over baking
Keep well ventilated
Hard Dough: crispy crust & paper bags
Soft Dough: Paper or plastic. Soft crust
Sweet Dough: glaze when hot. Lightly bagged or boxed
