Starch is the primary source of stored energy in cereal grains, including corn. When starch is separated from the rest of the kernel through the wet mill refining process, it becomes a versatile ingredient with a wide variety of applications and uses  – not only in food production, but throughout our economy. Some examples of the wide variety of household, personal, and healthcare items starch can be found in:

In foods and beverages, corn starch can thicken ingredients, retain moisture, offer freeze-thaw stability, stabilize ingredients, prevent separation, and replace fats. Literally thousands of supermarket staples are produced using both regular and specially modified corn starches.

Corn starch also plays a key role in everything from basic consumer necessities to highly specialized industries. Starches are found in paper products, crayons, and printer ink. Dextrins, formed by heating starch, are utilized as adhesives. Other types of starches are even used in the search for oil as part of the “drilling mud,” which cools down superheated oil drilling bits. Specialized starches are also used to remove water from fuels and to clean up pesticide spills.

Cyclodextrins, a family of specially modified starches, encapsulate other ingredients to protect sensitive or delicate ones and allow them to be released over time. As a result, they are commonly used in vitamins, flavorings, and medicines. Cyclodextrins are even found in laundry sheets, helping fragrances last longer.

One of the most promising new markets for corn starch is as a renewable replacement for petroleum feedstocks in the production of industrial chemicals and plastics. This process for converting corn starch into advanced, value-added products is often called bioprocessing.

 


Examples of Starches

Fireworks

Fireworks use cornstarch to increase their burn time and to give them their explosive quality.

Concrete

Starch products in cement increase strength and speed up set time. Corn syrup helps keep the surface even.

Crayons

Cornstarch is used to bind the ingredients in crayons, and the adhesive dextrin, a type of cornstarch, is used to attach their labels.


Examples of Food Starches

Healthier Eggs

Cyclodextrin, a cornstarch, can be used to significantly reduce cholesterol in egg yolks, and is found in products like heart-healthy mayonnaise.

Low Fat Yogurt

Cornstarch makes low-fat yogurt creamy, smooth, and tasty by enhancing texture and keeping all the ingredients evenly mixed.

Better Fried Chicken

Fried chicken is crunchier and healthier when the batter includes resistant dextrin, a cornstarch that cuts oil uptake, while keeping the meat moist.
