The Surprising Truth About White Bread Flour – What It’s Really Made Of
What To Know
- White bread flour, a staple ingredient in countless baked goods, is a refined wheat flour that undergoes a process to remove the bran and germ from the wheat kernel.
- This process results in a flour with a higher gluten content, giving it the ability to produce dough with a strong, elastic structure.
- Bread flour has a higher gluten content than white bread flour, so it can be substituted for white bread flour in recipes that require a strong, chewy texture.
White bread flour, a staple ingredient in countless baked goods, is a refined wheat flour that undergoes a process to remove the bran and germ from the wheat kernel. This process results in a flour with a higher gluten content, giving it the ability to produce dough with a strong, elastic structure.
Composition of White Bread Flour
White bread flour is primarily composed of:
- Starch: The main component of white bread flour, starch provides the energy for the yeast to grow and ferment.
- Gluten: A protein complex that forms the backbone of the dough, giving it strength and elasticity.
- Protein: Aside from gluten, white bread flour also contains other proteins that contribute to the dough’s structure and texture.
- Minerals: White bread flour contains small amounts of minerals such as iron, calcium, and potassium.
The Milling Process
White bread flour is produced through a multi-step milling process:
- Cleaning and Tempering: Wheat kernels are cleaned and tempered to soften them for milling.
- Breaking and Grinding: The kernels are broken down into smaller pieces and ground into a coarse meal.
- Sifting and Purification: The meal is sifted to separate the bran and germ from the endosperm.
- Bleaching and Enrichment: The endosperm is bleached to improve its appearance and enriched with nutrients to enhance its nutritional value.
Gluten Content
The gluten content of white bread flour is typically higher than other types of flour, ranging from 10% to 14%. This high gluten content allows the dough to form a strong, elastic network that traps gas during fermentation, resulting in a light and airy loaf of bread.
Uses of White Bread Flour
White bread flour is primarily used in the production of:
- White bread: The most common use of white bread flour is in the making of white sandwich bread, dinner rolls, and other white bread varieties.
- Pizza crust: White bread flour is often used to create a crispy and chewy pizza crust.
- Pastries: It can be used in certain types of pastries, such as croissants and puff pastry, to give them a light and flaky texture.
Nutritional Value
White bread flour is a refined product and has a lower nutritional value compared to whole wheat flour. However, it is still a good source of carbohydrates and protein.
- Calories: 100g of white bread flour contains approximately 364 calories.
- Carbohydrates: White bread flour is primarily composed of carbohydrates, providing 75g per 100g.

- Whole wheat flour: Whole wheat flour can be substituted for white bread flour, but the bread will be denser and have a more pronounced wheat flavor.
- Bread flour: Bread flour has a higher gluten content than white bread flour, so it can be substituted for white bread flour in recipes that require a strong, chewy texture.
Other Types of Flour
In addition to white bread flour, there are various other types of flour used in baking:
- Whole wheat flour: Contains all parts of the wheat kernel, resulting in a flour with a higher fiber content.
- All-purpose flour: A blend of hard and soft wheat flours, suitable for a wide range of baking purposes.
- Cake flour: A finely milled flour with a low protein content, used for tender cakes and pastries.
- Rye flour: Made from rye berries, rye flour has a slightly sour flavor and is often used in sourdough bread.
- Spelt flour: An ancient grain flour with a nutty flavor and high nutritional value.
