The use of wheat-derived ingredients in products labeled 'gluten-free' can be a source of confusion and concern for consumers. For certain King Arthur gluten-free products, like their Bread Flour and Pizza Flour, the ingredient list clearly states the inclusion of 'gluten-free wheat starch'. This seemingly contradictory label is the result of advanced food science that separates the starchy, gluten-free component of wheat from the gluten protein itself. This article explains the science behind this ingredient, clarifies who can safely consume it, and helps you understand which King Arthur products to choose based on your dietary needs.
Understanding Gluten-Free Wheat Starch
Gluten is the protein found in wheat, barley, and rye. In gluten-free wheat starch production, regular wheat flour is washed with water. The washing process removes the gluten protein, leaving behind a pure, gluten-free starch. This remaining wheat starch is then tested for gluten content. For a product to be labeled gluten-free, the U.S. Food and Drug Administration (FDA) requires it to contain less than 20 ppm of gluten. Many manufacturers, including King Arthur, adhere to the even stricter standards set by the GFCO, which mandates testing at less than 10 ppm of gluten.
Why Bakeries Use Wheat Starch in Gluten-Free Products
Baked goods that rely on yeast, such as bread and bagels, depend heavily on gluten for their structure. The gluten network traps gas, allowing the dough to rise and giving the final product its characteristic chewy texture and satisfying crumb. Traditional gluten-free flour alternatives often struggle to replicate this effect. By incorporating gluten-free wheat starch, King Arthur is able to closely mimic the taste, texture, and elasticity of conventional bread. This ingredient allows for the creation of classic yeasted recipes without compromising on the quality and flavor that bakers expect from King Arthur products.
The Crucial Distinction: Celiac Disease vs. Wheat Allergy
The most important takeaway for consumers is the difference between celiac disease and a wheat allergy. While both conditions involve adverse reactions to wheat, the triggers and necessary precautions are different.
- Celiac Disease and Gluten Intolerance: Celiac disease is an autoimmune disorder triggered by the ingestion of gluten protein. For most individuals with celiac disease, products that have been processed to remove gluten and rigorously tested to fall below the strict gluten-free threshold are safe to consume. However, some individuals with heightened sensitivity may still experience a reaction, so caution is advised.
- Wheat Allergy: A wheat allergy is an immune reaction to one of the many proteins found in the wheat plant. Since gluten-free wheat starch is still derived from wheat, it is not safe for individuals with a wheat allergy. These individuals must avoid all wheat-derived products, regardless of the gluten content.
King Arthur's Specific Products and Labeling
King Arthur Baking Company maintains a robust allergen program and is transparent about which of its products contain gluten-free wheat starch. It is essential to read the specific product label carefully, as not all of their gluten-free offerings are made with wheat starch. For example, their Gluten-Free All-Purpose Flour and Measure for Measure Flour do not contain wheat starch.
How to Identify the Right King Arthur Flour for Your Needs
To ensure you are choosing the right product for your dietary requirements, consider these steps:
- For yeasted goods: If you have celiac disease and want to bake artisanal bread, bagels, or cinnamon rolls, the King Arthur Gluten-Free Bread Flour or Pizza Flour (which contains wheat starch) is an excellent choice.
- For cakes, cookies, and non-yeasted items: If you have celiac disease, their Gluten-Free All-Purpose or Measure for Measure flour will work perfectly.
- For a wheat allergy: If you have a wheat allergy, you must avoid the Bread and Pizza flours containing gluten-free wheat starch entirely. The Gluten-Free All-Purpose flour is a safe alternative.

| Primary Flours | Wheat Starch, Corn Starch, Sorghum | Rice Flour, Brown Rice Flour, Tapioca Starch | Rice Flour, Tapioca Starch |
Potential Issues and Important Considerations
While King Arthur tests their gluten-free wheat starch to be compliant with gluten-free standards, consumer reactions can vary. A small number of celiac patients are highly sensitive to even trace amounts of gluten. For these individuals, a discussion with a healthcare provider or a dietitian is recommended before consuming products containing gluten-free wheat starch. The company's commitment to transparency means they explicitly state the presence of wheat starch on their labels and website, providing all the necessary information for consumers to make an informed choice.

Conclusion
When a King Arthur gluten free flour product contains wheat, it's a specific, highly processed ingredient called gluten-free wheat starch, not the whole wheat grain. This unique ingredient, with the gluten protein removed, allows for superior baking results in yeasted goods that are safe for most people with celiac disease. However, it is fundamentally important to understand that this ingredient is not safe for individuals with a wheat allergy. Always carefully read the ingredient list, especially on the Bread Flour and Pizza Flour, and select the product that aligns with your specific dietary restrictions.
