Is Cornstarch Gluten Free

Cornstarch is gluten free; corn is not a grain, so it doesn’t contain gluten. However, there may be other ingredients used to make cornstarch that aren’t gluten free so we can’t say it’s 100% safe for people with Celiac disease. But chances are, if you buy cornstarch in a regular grocery store, the product will be safe for you.

Yes Cornstarch is Gluten Free in Its Raw Form.

According to the Gluten Intolerance Group, cornstarch is gluten free

Cornstarch is made by grinding dried corn kernels into a powder. It’s used as a thickener in cooking and as a binder in cosmetics. Cornstarch is safe for people with celiac disease or a gluten sensitivity because it doesn’t contain any gluten protein.

However, some corn products may be contaminated with wheat and other grains that contain gluten. If you’re concerned about cross-contamination, look for organic cornstarch that’s labeled “certified gluten-free.”

Food label doesn’t list an ingredient as gluten-free

Cornstarch is made from corn, and corn isn’t naturally gluten-free. But as long as the corn starch you’re using is labeled “gluten-free,” it’s safe for people who follow a gluten-free diet. Cornstarch can be found in some processed foods like canned soups, sauces and puddings, but it’s also an ingredient in many other products such as breads, cakes and snacks.

If a food label doesn’t list an ingredient as gluten-free, you don’t know what it contains. That’s why if you’re following a gluten-free diet, you’ll want to double check that any packaged products you buy are labeled “gluten-free.”

Cornstarch is made from the endosperm of corn kernels

It’s used in baking to add body to recipes, and it can be used as a thickener for sauces and gravies. Cornstarch is gluten-free because it’s made from corn, which isn’t a grain at all. However, if you have a corn allergy or sensitivity, you may want to avoid using cornstarch.

Although it doesn’t contain gluten, it may cause an adverse reaction in some people who are sensitive to corn. Cornstarch can be found in most grocery stores and is inexpensive compared to other thickeners like arrowroot powder and potato starch. Cornstarch is made from the endosperm of corn kernels.

Cornstarch can be used as a thickener for sauces, soups and gravies, but it should not be used as a substitute for flour in recipes that call for baked goods. When buying cornstarch, look for a fine-textured product that dissolves easily in cold water and forms peaks when mixed with cold water.

Cornstarch is used as a thickener for soups, sauces and gravies, and in baking to help the batter rise and make it more tender

Some people with gluten sensitivities or celiac disease may find that they can eat cornstarch, but this will depend on your particular situation.

Corn starch is made from corn kernels. The skin is removed from the kernel, leaving the inner part of the kernel called the endosperm. The endosperm is then processed into cornstarch by grinding it into fine powder and drying it out. Cornstarch contains no gluten because there isn’t any protein in corn kernels to begin with.

When you cook with cornstarch, you are essentially combining two ingredients  water and starch  together in order to create a thickening effect. The result is a sauce or gravy with a smooth consistency instead of being runny or thin-looking like water alone would produce.

Cornstarch is in most powdered sugar because the starch acts as a flow agent to prevent clumping.

Cornstarch is gluten-free, but the grains that are used to make it can be contaminated with gluten during the growing, harvesting, and milling process. Corn is a member of the grass family and a distant relative of wheat. It’s also commonly called corn on the cob or maize.

  • Cornstarch may also be used as a thickening agent in sauces and gravies. Cornstarch doesn’t contain gluten proteins, but it’s often manufactured on equipment that processes wheat products, so it could have been contaminated before it was packaged for sale.
  • It is used as a thickening agent in sauces, gravies and puddings. It can also be used to thicken custards and pie fillings at room temperature.
  • You can use this product interchangeably with conventional cornstarch in recipes calling for 1 tablespoon of regular cornstarch per cup of liquid to be thickened (or 2 tablespoons if recipe calls for more than 2 cups liquid).
  • Use 3/4 teaspoon Gluten Free Corn Starch per cup of liquid (or 1 1/2 teaspoons if recipe calls for more than 2 cups liquid).


Cornstarch is safe for people with celiac disease or gluten intolerance to use in their cooking. While this starch has certain characteristics that are similar to wheat flour, it forms gluten at a much lower rate, so those who have never been exposed to the protein will likely be fine.
