Because corn starch absorbs moisture, it is critical to keep it in an air-tight container where it will not be exposed to 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.
