Is Baking Powder Corn Free?

Caution

Sometimes. Many commercial baking powder brands are made with either wheat or corn starch to prevent clumping. If the label does not specify, we recommend you contact the manufacturer.

Baking Powder and the Corn Free Diet

Baking powder is a dry chemical leavening agent used to increase the volume and lighten the texture of baked goods. It typically consists of an alkaline component (usually sodium bicarbonate) and an acid (such as cream of tartar), along with a starch to absorb moisture and prevent premature reactions. The starch is often cornstarch but can also be made with potato starch or other alternatives.
