Is Corn Starch Gluten-Free?

Celiac.com 07/12/2023 - We get a lot of questions about baking supplies and ingredients. Lately, we get a lot of questions about corn starch. More than a few people wonder if corn starch is gluten-free. The short answer is yes. 

Corn starch is a common ingredient used as a thickening agent in a wide range of food products, including soups, sauces, gravies, and baked goods. It provides a smooth and silky texture without adding any gluten-related concerns.

Celiac.com Sponsor (A12):
Corn starch is generally considered gluten-free. It is derived from corn, which does not contain gluten. However, it is important to note that cross-contamination can occur during the manufacturing process. If corn starch is produced in facilities that also handle gluten-containing ingredients, or if there is a risk of cross-contact with gluten during processing or packaging, there is a possibility of gluten contamination. In such cases a company is legally required to list wheat on the ingredient label as a potential allergen.

To ensure that corn starch is gluten-free, it is advisable to look for products that are specifically labeled as "gluten-free" or certified by reputable gluten-free certification programs. Additionally, reading ingredient labels and researching the manufacturing practices of the specific brand or product you are considering can provide further assurance of its gluten-free status.

If you have celiac disease or a gluten sensitivity, it's always best to consult with a healthcare professional or a registered dietitian for personalized guidance on your dietary needs and to address any specific concerns you may have.

Brands of corn starch that contains no gluten ingredients or is labeled gluten-free include:

• Argo Corn Starch
• Bobs Red Mill Corn Starch
• Clabber Girl Corn Starch
• Rumford Corn Starch

In almost all cases, corn starch is gluten-free and safe for people with celiac disease. Just be sure to read ingredients, and avoid anything with gluten.
