What is Corn Starch?
Cornstarch is an ultra fine starch that comes from corn. Corn is a grain that is considered gluten free. When you have celiac disease or need to avoid gluten due to an intolerance or allergy, you must avoid wheat, barley, and rye.
One of the fun things about cornstarch is that it is powdery and fine. It is milled from the endosperm of corn kernels. Starch is inexpensive to produce, making it a popular choice with manufacturers.
Cornstarch is used as a thickener for sauces, soups, and gravies. Cornstarch is also one of the ingredients found in many pre-mixed gluten free flour blends. It helps keep gluten free baked items soft and fluffy.

Answer: Is Cornstarch Gluten Free?
The answer is, in most cases, yes, cornstarch should be gluten free. You need to be careful of some things, so let's talk about the red flags to look for.
- Corn is often grown near wheat fields. It can get cross-contaminated in silos or during the farming process.
- Cornstarch can get cross-contaminated in the manufacturing process.
It is critical to read the ingredients label when you are buying cornstarch. The package should tell you if the product is gluten free or manufactured on equipment that processes wheat.
You can also go to the manufacturer's website for more detailed information. This will help you determine whether a bag of cornstarch is safe for those on a gluten free diet.
It is safe if you buy a certified gluten-free flour blend with cornstarch. This means it has been tested to be under the 20ppm rule to be labeled gluten free.
