Add the overview steps of milling
What are the flour types made from wheat
High-gluten flour (bread machine)
Whole wheat
Bread
All purpose
Pastry
Cake
What is the wheat type, gluten level, %pro, uses¬es of high-gluten flour (bread machine)
Wheat type: hard or blend
Gluten level: high
%protein: 14.5%
Uses¬es: used for yeast breads made in bread machines; desire chewier texture (bagels, pizza dough, artisan breads)
What is the wheat type, gluten level, %pro, uses¬es of whole wheat flour
Wheat type: hard
Gluten level: high
% protein: 14%
Uses¬es: used for yeast breads, quick breads, dough: mix 1/2 w/ white flour
What is the wheat type, gluten level, %pro, uses¬es of bread flour
Wheat type: hard
Gluten level: high
% protein: 12%
Uses¬es: yeast breads, hard rolls that need gluten for multiple rising periods
What is the wheat type, gluten level, %pro, uses¬es of all purpose flour
Wheat type: blend
Gluten level: medium
% protein: 10%
Uses¬es: yeast breads, quick breads, pastry, dough
What is the wheat type, gluten level, %pro, uses¬es of pastry dough
Wheat type: soft
Gluten: low
% protein: 9%
Uses¬es: pastries, some cookies, biscuits, muffins
What is the wheat type, gluten level, %pro, uses¬es of cake flour
Wheat type: soft
Gluten level: low
% protein: 8%
Uses: fine textured cakes
What are additives that can increase rise of high protein flours: Gluten (vital wheat gluten)
Add to whole grain or mixed grain flour to strengthen gluten
- 1-2 tbsp per 1 cup white flour
- 1.5 to 3 tbsp per 1 cup whole grain flour
Flour component’s role in baked goods: Protein
Purpose of gluten: trap gases, create structure for rise
High protein flours form more gluten (exception for whole wheat)
Factors that affect gluten development
- manipulation methods
- amount of liquid
- presence of lipids
- 1-2% fat is needed for gluten development
- >2% fat interferes w/ gluten formation
Flour component’s role in baked goods: Starch
Gelatinization
- absorbs water during cooking; fills gluten network
- structure: sets structure during baking, assists with formation of holes during crumb
