Quinoa - Overview

Overview

Quinoa (the name is derived from the Spanish spelling of the Quechua name kinwa or occasionally "Qin-wah") originated in the Andean region of Ecuador, Bolivia, Colombia and Peru, where it was successfully domesticated 3,000 to 4,000 years ago for human consumption, though archeological evidence shows a non-domesticated association with pastoral herding some 5,200 to 7,000 years ago.

Similar Chenopodium species, such as pitseed goosefoot (Chenopodium berlandieri) and fat hen (Chenopodium album), were grown and domesticated in North America as part of the Eastern Agricultural Complex before maize agriculture became popular. Fat hen, which has a widespread distribution in the Northern Hemisphere, produces edible seeds and greens much like quinoa, but in smaller quantities.

The nutrient composition is very good compared with common cereals. Quinoa grains contain essential amino acids like lysine and good quantities of calcium, phosphorus, and iron.

After harvest, the grains need to be processed to remove the coating containing the bitter-tasting saponins. Quinoa grains are in general cooked the same way as rice and can be used in a wide range of dishes. Quinoa leaves are also eaten as a leaf vegetable, much like amaranth, but the commercial availability of quinoa greens is limited.
