What To Know
- Bakers need to know the yield to determine the amount of wheat required for a desired quantity of flour.
- Understanding the factors that influence flour yield is essential for bakers, flour millers, and anyone interested in the art of flour production.
- Extraction rate refers to the percentage of flour obtained from the original wheat kernel, while flour yield is the actual amount of flour produced from a specific quantity of wheat.
Are you curious about the transformative journey of wheat into flour? Join us as we delve into the intricacies of wheat grinding and unveil the secrets of flour yield.
The Flour Extraction Rate
When grinding wheat, the amount of flour you obtain depends on the extraction rate. This rate represents the percentage of the original wheat kernel that ends up as flour. The extraction rate is influenced by several factors, including the type of wheat, the grinding process, and the desired flour grade.
Factors Affecting Flour Yield
1. Wheat Variety
Different wheat varieties exhibit varying flour yields. Hard wheat, with its high protein content, typically yields more flour than soft wheat.
2. Grinding Process
The grinding method plays a crucial role in determining flour yield. Stone milling, a traditional technique, produces flour with a higher extraction rate compared to roller milling, which is more common in industrial settings.
3. Flour Grade
The desired flour grade also affects the yield. Whole wheat flour, which includes all parts of the kernel, has a higher extraction rate than white flour, which is refined to remove the bran and germ.
Average Flour Yield from 1kg Wheat
On average, grinding 1kg of wheat typically yields around:
- Whole wheat flour: 650-750 grams
- White bread flour: 550-650 grams
- Cake flour: 450-550 grams
Why the Yield Varies
The flour yield can vary slightly depending on the specific factors mentioned above. For instance, hard red spring wheat, commonly used for bread making, tends to yield more flour than soft white wheat, suitable for pastries.
Importance of Flour Yield
The flour yield is crucial for bakers and flour mills. Bakers need to know the yield to determine the amount of wheat required for a desired quantity of flour. Flour mills optimize their processes to maximize flour yield while maintaining the desired quality.
How to Calculate Flour Yield
To calculate the approximate flour yield from 1kg wheat, follow these steps:
1. Determine the extraction rate for the desired flour grade.
2. Multiply the extraction rate by 1kg.
For example, to estimate the yield of whole wheat flour with an extraction rate of 70%:
“`
Flour yield = 70% x 1kg = 700 grams

Key Points: Unlocking the Secrets of Flour Yield
Understanding the factors that influence flour yield is essential for bakers, flour millers, and anyone interested in the art of flour production. By considering the wheat variety, grinding process, and desired flour grade, you can optimize your flour yield and create delicious baked goods or high-quality flour products.
Questions We Hear a Lot
Q1: Can I grind wheat at home to make flour?
A: Yes, it is possible to grind wheat at home using a grain mill or blender. However, the yield and flour quality may vary compared to commercial milling.
Q2: What is the difference between extraction rate and flour yield?
A: Extraction rate refers to the percentage of flour obtained from the original wheat kernel, while flour yield is the actual amount of flour produced from a specific quantity of wheat.
Q3: How can I maximize the flour yield from wheat?
A: Choose hard wheat varieties, use a stone mill for grinding, and opt for whole wheat flour or higher extraction rate flours.
