Coreopsis (tickseed) is a genus of Asteraceae flowering plants native to North America, Hispaniola, and Peru, first published by Linnaeus in 1753. Species counts vary by treatment (39 accepted by Kew; about 120 in older floras); C. lanceolata is invasive in Japan.

Coriaria

Coriaria, sole genus of Coriariaceae in Cucurbitales, is a shrub genus with a strikingly disjunct Mediterranean, Himalayan, Australasian, and American distribution, nitrogen-fixing root nodules, and picrotoxin-like toxins (tutin, coriamyrtin).

Corm

Corm: a short, solid, swollen underground stem with a basal plate, terminal bud, and papery tunic that stores food for plants such as crocus, gladiolus, crocosmia, and cyclamen; unlike a bulb it is stem tissue, and each corm is annually replaced.

Cormus domestica

Cormus domestica, the true service tree (syn. Sorbus domestica L.), is a monospecific Rosaceae genus and wild fruit tree of southern Europe and northwest Africa, with bletted sorb-apple fruits, fissured bark, and a disputed taxonomy between Cormus, Sorbus, and Pyrus.

Corn bran arabinoxylan

Corn bran arabinoxylan, a highly branched cereal hemicellulose from maize bran (soluble corn fiber, AgriFiber SFC), with 74–90% dietary fiber, GRAS status via GRN 1073, and slow-fermenting prebiotic properties.

Corn hull fiber

Corn hull fiber: dietary fiber ingredient from corn pericarp/hull milling co-products; GRAS under FDA GRN 427 (Z Trim Holdings, 2012), used at 0.25–3.0% as formulation aid and fiber source in foods.

Corn kernel

A corn kernel, also called the maize kernel, is the seed of the maize plant, made up of a germ, a starchy endosperm, and an outer pericarp.

Corn nut

Corn nuts are whole corn kernels, typically Cuzco giant white corn, soaked and then roasted or deep-fried until hard and crunchy; despite the name they contain no nuts. The US commercial version began in Oakland, California in 1936, and the CORN NUTS brand is now owned by Hormel Foods.

Corn silk

Corn silk (Stigma maydis), the style and stigma of maize, is a corn by-product used in traditional Chinese medicine and as a GRAS flavoring; rich in flavonoids and polysaccharides with diuretic, hypoglycemic, and antioxidant effects studied mainly preclinically.

Corn starch

Corn starch (cornstarch, maize starch) is the starch from corn endosperm, about 80% of world starch production; granules 5–30 µm, 25–28% amylose, gelatinizes at 45–80 °C, used as thickener and industrial raw material.

Corn steep liquor

Corn steep liquor (CSL, condensed fermented corn extractives, CAS 66071-94-1) is a byproduct of corn wet milling: concentrated water-soluble corn steep extracts rich in amino acids and lactic acid, used in animal feed and fermentation media such as penicillin production.

Corn syrup

Corn syrup, also called glucose syrup, is made by partial hydrolysis of corn starch with acids or enzymes, yielding glucose, maltose, and higher saccharides; essentially 100% glucose, GRAS-affirmed, and the base for HFCS 42 and HFCS 55.

Corn tortilla

Corn tortilla: unleavened Mesoamerican flatbread of nixtamalized maize (masa), defined by Mexican NOM standards; ~30 g, 60 kcal each; staple of Mexico, base of the taco.
