Corncob
From Wikipedia, the free encyclopedia
A corncob is the central wooden core of a maize (Zea mays ssp. mays L.) ear. Young ears, also called baby corn, can be consumed raw. But as the plant matures the cob becomes tougher until only the kernels are edible. When harvesting corn the corncob is collected as part of the ear, leaving the corn stover in the field.
Corncobs are an important source of the furfural, an aromatic aldehyde used in a wide variety of industrial processes. Although with little nutritious value, corncobs can be used as fiber in ruminant fodder.
