Chapter Objectives • After studying this chapter, you will be able to: • understand how to purchase and store fruits appropriate for your needs. • understand the function of bakeshop flavoring ingredients.
Flours • Produced when grain kernels are ground to powder • Grains are grasses that bear edible seeds. • Wheat flour is the most important ingredient in the bakeshop.
Function of Flours in the Bakeshop • Provide bulk and structure to baked goods • Thicken liquids in items such as custards and pie fillings • Prevent foods from sticking
Producing Wheat Flour • Milling reduces wheat kernels to its component parts. • Bran • Endosperm • Germ
Composition of Wheat Flour • Consist of five nutrients: • Fat (<1%) • Minerals (<1%) • Moisture (<15%) • Starches (63-77%) • Proteins (6-18%) • Enzymes, proteins in flour, are important for flour performance in yeast bread. continued on next slide
Composition of Wheat Flour • Gums • primarily pentosans • another component of the carbohydrates in flour • 2-3% • absorb up to 10 times their weight in water
Types of Flour • Among the primary types of wheat flour: • Cake flour • Pastry flour • All-purpose flour • Artisan bread flour • Bread flour continued on next slide
Types of Flour • Among the primary types of wheat flour: • Whole-wheat • High-gluten flour • Durum flour • Vital wheat gluten
Specialty Flours • Among the types of flour used in the bake shop are the following specialty flours: • Whole-wheat flour • Wheat germ • Vital wheat gluten
Nonwheat or Composite Flours • Rye flour • Cornmeal • Oats • Rice flour
Sugars and Sweeteners • Carbohydrates that: • provide flavor and color to baked goods • tenderize products by weakening gluten strands • provide food for yeasts • serve as preservatives • act as creaming or foaming agents to assist with leavening
Sugars • Classified as either: • Simple or single • Complex or double
Forms of Sugars and Sweeteners • Turbinado • Sanding • Granulated • Brown • Superfine or castor • Powdered or confectioner's • Fructose
Liquid Sweeteners • Achieve the same benefit as sugar except for leavening • May be hygrocospic (water-attracting)
Forms of Liquid Sweeteners • Corn syrup • Glucose • Invert sugar • Honey • Malt • Maple syrup • Molasses
Sugar Syrups • Sugar can be incorporated in its dry form or when liquefied into a syrup. continued on next slide
Sugar Syrups • Sugar syrups take two forms: • Simple syrups • Mixtures of sugar and water • Cooked syrups • Made of melted sugar cooked until it reaches a specific temperature • The syrup's density (concentration) is dictated by the purpose.
Fats • Butter, lard, margarine, shortening and oil. • With proper mixing, fat particles are evenly distributed, causing fat and liquid to emulsify.
Function of Fats • Provide flavor and color to baked goods • Add moisture and richness • Assist with leavening • Help extend a product's shelf life • Shorten gluten strands, producing tender baked goods
Types of Fats • Butter • Fatty substance produced by agitating cream • Contains at least 80% milkfat • May or may not contain salt continued on next slide
Types of Fats • Butter • Many forms • Salted butter • European-style butter • Whipped butter • Clarified butter continued on next slide
Types of Fats • Lard is rendered pork fat. • Margarine is manufactured from animal or vegetable oil. • Oil may be extracted from a variety of plants. • Unlike butter or solid fats, oil blends thoroughly into a mixture.
Fats are Shortenings • Any fat is a shortening and tenderizes the product. • Hydrogenation process hardens liquid fats. • Consumption of excess trans fats, a byproduct of hydrogenation, is a risk factor for diseases.
Milk and Dairy Products • Provide texture, flavor, volume and color to baked goods • Add nutritional value • Contribute to browning as well as softness in the crust and structure of baked items
Milk Safety • Highly perishable, milk is an excellent breeding ground for bacteria. • Pasteurization destroys pathogenic bacteria.
Forms of Milk • Whole • Evaporated • Sweetened condensed • Dry milk powder
Cream • Cream is rich milk containing at least 18% fat. • Half-and-half • Light cream, coffee cream and table cream • Whipping cream • Heavy cream • Clotted cream
Cultured Dairy Products • Cultured dairy products are produced by adding specific bacteria to fluid dairy products. • Buttermilk • Sour cream • Crème fraîche • Yogurt
Cheese • Cheese is milk protein coagulated and then separated (whey from curd). • One of the oldest and most widely known foods to man, cheese comes in various forms.
Fresh Cheese • Fresh cheeses used in the bakeshop include: • Cream cheese • Farmer's, baker's and quark • Mascarpone • Ricotta
Eggs • Flavor, leaven and thicken items • Bind ingredients in batters, coatings and doughs • Enrich and tenderize yeast breads • Extend the shelf life of some baked goods
Parts of an Egg • Yolk is the bright yellow portion containing most of the minerals and vitamins and all the fat. • Albumen, or egg white, is clear, containing half the protein. • Chalazae cords anchor the yolk in place.
Egg Safety • Eggs are TCS foods. • Cook products containing whole eggs above 145°F (63°C). • Chill products containing eggs over an ice bath and keep at 40°F (4°C) or below. • Use pasteurized eggs in products that will not be cooked such as meringue or ice cream base.
Thickeners • Absorb moisture to thicken liquids • Starch, pectin or vegetable gums • Trap liquids in a protein structure • Gelatin • Starches, gelatin and vegetable gums are thickening agents.
Starches • Cornstarch • Waxy maise • Arrowroot • Tapioca
Gelatin • Gelatin is a thickener derived from collagen. • Granulated • Sheet or leaf
Gums • Vegetable gums bind water to thicken liquids. • Pectin
Fruits • Add flavor, moisture, texture, body and taste to baked goods • Are organs developed from the ovary of a flowering plant containing one or more seeds • Are a perfect snack food and a key ingredient in the pastry chef's pantry
Hybrids and Varieties • Hybrids • Crossbreeding fruits from different species • A unique product results • Varieties • Breeding fruits from the same species • Results in a fruit with the best qualities of both parent fruit
Berries • Small, juicy fruits that grow on vines and bushes worldwide
Berries • Thin-skinned with many tiny seeds, they must ripen on the vine: • Blackberries • Blueberries • Cranberries • Currants • Raspberries • Strawberries
