Corn Starch
How Does Corn Starch Thicken?
Corn starch is comprised of long chains of starch molecules, which when heated in the presence of moisture, will unravel and swell.This swelling action, or gelatinization, is what causes the thickening to occur.
Tips for Using Corn Starch
Corn starch should not be added straight into a hot liquid as this can cause it to clump and form lumps. Corn starch should first be mixed into a room temperature or slightly cool liquid to form a slurry, and then stirred into the hot liquid. This will allow for even distribution of the corn starch molecules before they have a chance to swell and gelatinize.
Mixtures containing corn starch should be brought to a full boil before cooling. Under heating corn starch mixtures can cause them to seep moisture or become thin again upon cooling.The mixture may appear thickened after a sligt
heating, but if the starch molecules are not fully gelatinized, they will release the moisture once cooled. Sauces and other mixtures thickened with corn starch should not be frozen.Freezing will break down the gelatinized starch matrix and the mixture will become thin after thawing.
How to Store Corn Starch
Because corn starch absorbs moisture, it is critical to keep it in an air tight container where it will not be exposed to ambient humidity.
Corn starch should also be kept away from extreme heat. Store your corn starch in a sealed container and in a cool, dry place. When stored properly, corn starch will last indefinitely.
