thumb|A cross-section of an ear of corn, showing the cob.A corncob, also called corn cob or cob of corn, is the hard core of an ear of maize, bearing the kernels, made up of the chaff, woody ring, and pith. Corncobs contain mainly cellulose, hemicellulose, and lignin. The cob is not toxic to humans and can be digested, but the outside is rough and practically inedible in its original form. The foamy pith has a peculiar texture when mature and is completely bland, which most people would find unappealing, due to the consistency similar to foam plastic.
