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 rind of corn stalk (Zea mays L.) contains a high content of lignin, which is difficult for ruminants to digest. So, the separation of the pith and rind is the basis for the effective use of corn stalk.

Researchers have used corn stalk rind as a straw fiber to compound a mulching film and found the fiber mulching film can inhibit grass growth, increase crop yield, and increase soil water content when it is laid on farmland (Liu et al. 2017; Zhang et al. 2014).

The thermal stability of corn stalk rind was investigated before and after removing the epidermis and gluing of the material using the hyphenated technique by simultaneous thermal analysis (STA), Fourier transform infrared spectroscopy (FT-IR), and gas chromatography-mass spectrometry (GC-MS).

May 1, 2012 · This paper investigated cell morphology, chemical components, lignin distribution and inorganic elements distribution of corn stover fractions. Corn stover fractions, classified as stalk rind, stalk pith and leaf, had different tissues, cell morphology and chemical compositions.

The test results show: The content of rind is highest in the middle of the stem, the content of xylem is highest in the bottom of the stem, and the content of pith is highest in the top of the...

Nov 1, 2012 · To design and optimize the parameters of separation equipment for rind, pith and leaf of corn stalk, tensile and shearing characteristics of rind of corn stalk were studied via quadratic...

Nov 1, 2012 · To design and optimize the parameters of separation equipment for rind, pith and leaf of corn stalk, tensile and shearing characteristics of rind of corn stalk were studied via quadratic orthogonal rotatory combination design in this paper.

The corn stalk rind has significant differences in fiber morphology, chemical composition and mechanical properties at different heights. Nano-SiO2 composite material contained in the epidermis of corn stalk rind is not conducive to exert adhesive into a board.

The research findings provide the theoretical basis for the design of corn stalk processing equipment and promote the utilization of corn stalk rind as material.
