1 8.1 Bakeshop Basics

2 Ingredients Category Examples Strengtheners Fats/Shortening Sweeteners
Flour, eggs, milk powder Fats/Shortening Butter, oils Sweeteners Sugars, syrups Flavorings Vanilla, nuts Leaveners Baking powder, Baking soda, yeast, steam, air (chemical, organic, physical) Thickeners Cornstarch, flour, eggs Liquids Water, milk, cream, eggs, honey, molasses, butter Additives Food coloring

3 Strengtheners Provide stability ensuring baked items don’t collapse once removed from oven Includes: Flour several types…later Egg proteins (whites & yolk) Dry milk powder

4 Fats/Shortenings Contribute moistness, flavor, tenderness, and keeps baked goods fresh longer Lipids ‘shorten’ doughs by coating them, preventing water absorption and structure formation Fats that are rubbed or rolled in create flakiness, when creamed result in a smooth, soft, cake-like texture Shortening is 100% fat; butter 85% Emulsifiers (high ratio) mono & diglycerides increase fat dispersion in a batter, allowing for a higher ratio of water and sugar to flour, producing a moister, more tender, finer crumb cake

5 Sweeteners Add flavor and color, Browning, Caramelization
Tenderizes by interfering with gluten formation, protein coagulation, and starch gelatinization: delaying formation of structure Moistens because of its hygroscopic nature Contributes to aeration

6 Leaveners- Process Allow products to rise (leaven)
“As gases expand from the heat of the oven, the force from these expanding gases pushes on the wet flexible cell walls causing them to stretch. As long as structure builders stretch without excessive breaking, volume increases. When baked goods are removed from the oven, gases contract back to their original volume. Products with strong structure retain their shape. Those with weak structure-like soufflés and underbaked cakes-shrink in size as the gases contract.” -Figoni, Paula, “How Baking Works”. Wiley 2004

7 Leaveners- Categories
Leavening agents by type: Air Steam Carbon dioxide (alcohol, ammonoia) Leavening agents by methods: Physical Organic (Biological) Chemical

8 Leaveners Ingredients -Physical
Steam (water vapor) Forms when water, milk, eggs-any moisture containing ingredient is heated Can expand to occupy over 1600 times more space than water All baked goods rely on steam for at least some of their leavening Also discuss bread crust & choux pastry

9 Leaveners Ingredients -Physical
Air Added by physical means: Foaming method: whipped egg whites, angel food/sponge Creaming method: beat ingredients (fat & sugar) until soft, smooth and creamy, homogeneous, not separated, and without particles (sugar) whipping, sifting, folding, kneading, stirring Small air bubbles added during mixing stage are “seed” cells. During baking steam and carbon dioxide migrate to seed cells, enlarging them No new air cells are created

10 Leaveners Ingredients- Organic (Biological)
Yeast Microscopic fungus, breaks down sugars and carbohydrates (if amylase is present) during fermentation , giving it the energy to reproduce and waste CO2 and alcohol. The carbon dioxide leavens and the almost equal amount of alcohol evaporates and expands during early stages of baking, adding to “oven spring”. Fermentation also produces flavor: preferments/starter

11 Leaveners Ingredients- Organic (Biological)
Yeast: Factors affecting fermentation Temperature: Amount of Salt Retards yeast fermentation % (BP) is generally used 32-34°F. Dormant 50°F. Beginning activity 60-70°F. Slow activity 70-95°F. Optimum activity °F. Reducing activity °F. Yeast die

12 Leaveners Ingredients- Organic (Biological)
Yeast: Factors affecting fermentation Sugar amount Small quantities ≤ 5% (BP) increase yeast activities Large quantities ≥ 10% (BP) slow fermentation Sweet doughs often use a sponge, allowing for fermentation, adding sugar with rest of ingredients, or using osmotolerant yeast. Sugar type Sucrose, glucose, fructose are fermented quickly Maltose is fermented slowly Lactose is not fermented at all

13 Leaveners Ingredients- Organic (Biological)
Yeast: Factors affecting fermentation pH Optimum is 4-6 Above and below fermentation slows (as yeast ferments it produces acids that lower it to that range Antimicrobial agents Can slow or stop fermentation– calcium proprionate, cinnamon Yeast amount The more yeast the faster the fermentation

14 Leaveners Ingredients- Organic (Biological)
Yeast: Type Fresh Compressed Moist cake or block, 30% yeast Refrigerate up to 2 weeks, wrapped in plastic Frozen, 3-4 months Light grayish color Do not use if dark, dry, or off aroma Dissolve in twice its weight 100°F. water

15 Leaveners Ingredients- Organic (Biological)
Yeast: Type Dry Active Spray-dried to <10% moisture Harsh treatment, 25% dead cells Glutathione, detrimental to quality of dough Dissolve in 4x weight ° water Use about half (.4) as much as compressed Once opened, shelf life or a couple months, longer if refrigerated or frozen

16 Leaveners Ingredients- Organic (Biological)
Yeast: Type Instant Can (and should) be directly added to dough Gentler method, more live yeast More vigorous than compressed or dry active Best for shorter fermentation Use a % as much as compressed Initial dough temperature should be between 70-95°F Shelf life unopened- 1 year, refrigerate several months or freeze

17 Chemical Leaveners Baking Soda: Sodium bicarbonate: NaHCO3
Alkaline, base Releases carbon dioxide CO2 when both acid and moisture are present Must be baked at once to prevent leavening loss Common acids used Buttermilk, sour cream, lemon juice, honey, molasses, fresh fruit

18 Chemical Leaveners Baking Powder: mixture of baking soda and one or more acids generally cream of tartar NA2SO4 and sodium aluminum sulfate Al2[SO4]3 (SAS) or monocalcium phosphate CAH4[PO4]2 (MCP) Single acting: not often used, only needs moisture for reaction Double acting: most common, reacts with moisture and provides a secondary reaction with heat Baking Ammonia: provides a rapid release in dry, large surface area products (crackers)

19 More on Chemical Leavening
As baking soda comes in contact with an acid such as sour cream, thousands of tiny bubbles (CO2) are released. When heated the bubbles expand, causing the product to rise. Baking powder, which already has the acid, produces CO2 when combined with water. Double Acting baking powder releases CO2 a second time under the influence of heat.

23 Thickeners Include: Gelatin Flour Arrowroot Cornstarch Eggs Thickeners combined with stirring process determine the consistency of the finished product Crème anglaise (sauce) → custard (free standing)

24 Thickeners Can thicken by adding thicker ingredients- or reducing
Thickening occurs when water and other molecules in a product move around more slowly More often we thicken when we add ingredients that: Cause molecules to entangle: protein coagulation, eggs, custard Cause water to be trapped inside starch granules: flour/cornstarch, sauce/pie Cause air bubbles in foams or fat droplets in emulsions to slow water movement: whipped cream, mayo Prevent water from moving around at all: gelatin

25 Thickeners Some agents both thicken or gel depending on amount
Gelatin, cornstarch, pectin Others only thicken Guar gum, gum arabic, waxy maize starch

Sheets absorb 5x weight in water. Convert from powder to sheet in recipe: calculate water absorbed by sheet (5:1), add more water if called for. Convert from sheet to powder in recipe: calculate sheet weight, multiply by 5 for water. MELT to 130°F. for optimum gelling properties. Do not allow solution to boil. Hydrating in solutions with high concentrations of sugar, salt or dairy will increase hydration time.

39 Function of Flour Structure (toughens) Absorbs Water (drier)
Gluten as in yeast breads, pie crust, crisp cookies Starch (gelatinization) as in cakes, pastry cream, pie fillings Absorbs Water (drier) Binds ingredients together Contributes Flavor Mild, slightly nutty Contributes Color Nut brown to stark white Adds Nutritional Value Complex carbs, vitamins, minerals and proteins

40 Note on Absorption Value
In bread dough, starch holds ½ the water, and proteins about ⅓ However, proteins hold 2x their weight in water, while starch holds ¼ to½ its weight Protein is a better predictor of absorption Except chlorine bleached (cake), a process which allows for greater absorption, as does the finer grind

41 The Baking Process- Effects of Heat
Gases Form: air, steam, carbon dioxide. Expanding when heated Gases Trapped: within a streachable network of egg or gluten proteins Starches Gelatinize: at approximately 140°F. starch granules absorb up to 10x their weight, expanding, and contributing to structure Proteins Coagulate: at about 160°F., the gluten, dairy and egg proteins provide structure Fats Melt: steam is released, and fat droplets dispersed, coating starch granules moistening and tenderizing

42 The Baking Process- Effects of Heat
Water Evaporates: steam leavens, batters start to dry out starting from outside Sugars Caramelize: above 320°F. adding flavor and color Caryover Baking: products continue to bake once out of oven. Staling: change in a baked good’s texture caused by moisture loss and starch retrogradation Rapidly at about 40°F. Do not refrigerate baked goods unless containing TCS

43 Baking Math

44 Baker’s Percentage Standardized recipes for bakery products are called formulas Proportions for each ingredient are given in percentages A percentage is part of a whole When using Baker’s Percentage, flour is always 100% All other ingredients are calculated in relation to the flour Weight of Ingredient ÷ (Weight of Flour x 100 percent) = Percent of ingredient

45 Basic Bread % Ingredient Weight 100 Flour, bread 10 # 3.75
Oil, neutral 6 oz. 1.25 Salt, D. Kosher 2 oz. 60 Water 6 # 1.5 Yeast, instant 2.5 oz. 166.5

46 40% Whole Wheat Bread % Ingredient Weight 60 Flour, bread 6 # 40
Flour, whole wheat 4 # 3.75 Oil, neutral 6 oz. 1.25 Salt, D. Kosher 2 oz. Water 1.5 Yeast, instant 2.5 oz. 166.5

47 BAKING MATH Baker’s Percentage Flour = 100% Calculate IP (Ingredient Percent) IW / TFW Ingredient Weight / Total Flour Weight Calculate IW Ingredient Weight IP x TFW Ingredient Percent x Total Flour Weight Calculate TFW Total Flour Weight TW / TP Total Weight / Total Percent Convert to New Yield: change Total Percentage to decimal. Divide Desired Yield by Total Percentage (decimal) to get New Flour Weight. NFW = DY ÷ TP
