Gluten-Free Corn Starch

Corn starch is another popular ingredient in gluten-free baking, prized for its affordability and versatility. Not only is it used extensively in home baking, but it also finds applications in industrial gluten-free food production and even in cosmetics.

Corn starch was first produced in the mid-19th century in the United States. The development of industrial processes for textile treatment led to the extraction of starch from corn. It wasn’t until later that its culinary uses were discovered. This contrasts with tapioca starch, which has been known and used by humanity for thousands of years.

To make corn starch, corn kernels are soaked in water with added sulfur dioxide for two days. This process softens the kernels and allows the starch to be separated. The kernels are then ground, and the starch, germ, and fiber are separated. The clean starch is washed and dried, resulting in a fine white powder. The initial soaking stage is a common point of contention for those who oppose corn starch.

Despite this, corn starch remains one of the most widely used ingredients. Its lack of flavor makes it ideal for adding texture to gluten-free recipes. However, like other starches (such as tapioca or potato starch), corn starch is purely a carbohydrate with no nutritional content. It’s important to note that for individuals with diabetes, it may not be the best ingredient choice.

Corn starch can be substituted with other starches like tapioca and potato starch in recipes.
