The Definitive Answer: Yes, and Here's Why
For those on a gluten-free diet, navigating the grocery store can be a minefield of potential cross-contamination risks. A common question arises about staple ingredients like corn starch, which is derived from a naturally gluten-free grain. While corn itself is gluten-free, the manufacturing process can introduce gluten from shared equipment or facilities. This is where Bob's Red Mill stands out with its certified gluten-free corn starch.
Bob's Red Mill has taken significant steps to ensure the integrity of its gluten-free products. The company manufactures its corn starch in a facility that is 100% dedicated to gluten-free production. This eliminates the possibility of cross-contact with other grains containing gluten, which is a common concern for individuals with celiac disease or severe gluten sensitivities. In addition to the dedicated facility, the product is batch-tested to confirm it meets the company's stringent gluten-free protocols. This rigorous testing process provides an extra layer of assurance for consumers who rely on these products for their health.
Understanding the Difference: Generic vs. Bob's Red Mill Corn Starch
Not all corn starch is created equal, particularly when it comes to guaranteeing a gluten-free status. While pure corn starch is inherently gluten-free, it's the journey from the corn kernel to the package that matters. The potential for cross-contamination in facilities that also process wheat or other gluten-containing grains is a real and dangerous risk for those with celiac disease. This is why certification is so important.
Dedicated Facility and Batch Testing
Bob's Red Mill's commitment goes beyond simply using a naturally gluten-free ingredient. Their dedicated gluten-free facility is a physical separation that ensures no gluten enters the production line. This is a critical distinction from other brands that might process gluten-free products on the same equipment as their gluten-containing counterparts, even with cleaning procedures in place. For those with celiac disease, even trace amounts of gluten can cause a reaction, so this level of precaution is essential. Bob's Red Mill also uses an ELISA Gluten Assay test in its quality control laboratory to confirm products remain gluten-free.
Beyond the Corn: How Cross-Contamination is Avoided
The rigorous process at Bob's Red Mill starts from the source. Ingredients are tested upon arrival at the mill and held until the results confirm gluten levels are below 20 parts per million (ppm) before being accepted into the dedicated facility. Further testing occurs during and after processing, ensuring the final product is consistently safe. This comprehensive approach ensures that the integrity of the product is maintained from the farm field to the final package, giving consumers confidence in every batch.

A Comparison of Corn Starch Products
This table highlights the key differences between Bob's Red Mill's certified gluten-free corn starch and a generic, non-certified alternative. These distinctions are crucial for making an informed choice, especially for those with celiac disease or significant gluten sensitivities.
| Feature | Bob's Red Mill Corn Starch | Generic Corn Starch (Non-Certified) |
|---|---|---|
| Manufacturing Facility | Dedicated, 100% gluten-free facility. | May be processed in a facility that also handles wheat and other gluten-containing grains. |
| Cross-Contamination Risk | Extremely low due to dedicated facility and rigorous testing. | Elevated risk due to shared equipment or a non-segregated environment. |
| Gluten Testing | Batch-tested in-house using ELISA Gluten Assay to confirm gluten-free status. | Testing procedures can vary, with no consistent guarantee of gluten levels below 20 ppm. |
| Labeling | Clearly labeled with a red "GF" logo and a statement of gluten-free testing. | May not carry a gluten-free label or certification, relying on the fact that corn is naturally GF. |
| Target Audience | Primarily individuals with celiac disease, gluten sensitivity, or those prioritizing certified GF products. | General consumers, not suitable for those who need to strictly avoid gluten unless they can confirm sourcing. |
How to Use Bob's Red Mill Corn Starch in Gluten-Free Cooking
Using Bob's Red Mill corn starch is an excellent way to thicken sauces and gravies or to improve the texture of gluten-free baked goods. Here are a few tips and applications:
- For Thickening: When thickening hot liquids like sauces, gravies, or soups, always mix the corn starch with a small amount of cold water first to create a smooth slurry. This prevents clumping when added to the hot liquid. Stir constantly and bring the mixture to a boil for one minute to activate the thickening power.
- For Crispy Coatings: For crispier baked goods or fried items, a light dusting of corn starch before cooking can make a big difference. It creates a light, crispy texture for items like gluten-free fried chicken or tofu.
- For Tender Baked Goods: In baking, corn starch is often used in combination with other gluten-free flours to add softness and tenderness. It can help create a lighter, more crumbly texture in recipes like gluten-free shortbread.
- As a Flour Substitute: As a rule of thumb, corn starch is a more powerful thickener than wheat flour. Use half the amount of corn starch as you would flour to achieve the same thickening effect.
- Store Properly: Store your corn starch in a cool, dry place in a tightly sealed container to maintain freshness and prevent clumping.
Conclusion
For anyone on a gluten-free diet, Bob's Red Mill corn starch is a safe and reliable choice. While corn starch is naturally free of gluten, the manufacturing process is a critical consideration for avoiding dangerous cross-contamination. Bob's Red Mill eliminates this risk by processing its corn starch in a dedicated, 100% gluten-free facility and conducting rigorous batch testing. This level of care and commitment provides the assurance needed for individuals with celiac disease and gluten sensitivities to use this product with confidence in all their cooking and baking needs. By choosing a certified gluten-free product from a trusted brand, you can ensure the safety and integrity of your meals and recipes.
