Corn cob, or Maize cob, is the central part of a maize ear, or bit of a cob. It is a prominent part of the hardy cereal grass found in tropical and subtropical regions and a common source of food throughout the world. Corn cobs account for approximately 75% the volume of a mature corn ear, and are composed of a husk and its components, including immature kernels and horny-tipped stigmas. Corn cobs are typically harvested for their starchy kernels as corn grain, but may also be cut green as cob silage or dried for other uses such as fodder or fuel. Corn cobs can also be used in several different industries, ranging from paper production to composites manufacturing.
