Similar to amaranth and buckwheat, quinoa (pronounced keen-wah fits within the pseudo-cereal group as it is not part of the Poaceae botanical family, in which true grains belong. It's loosely grouped as a pseudo-cereal with other grains as it's nutritionally similar and used in similar ways to true grains.

Quinoa originates from the Andes, where it has long been cultivated by the Inca people. It is a small, typically light-colored round grain (although it also available in other colours including red, purple and black), similar in appearance to sesame seeds.

To help ward off insects and birds, quinoa has a bitter residue of saponins, a natural occurring plant-defence. Most quinoa sold today has already been washed, but it is still advisable for consumers to thoroughly rinse the quinoa seeds under running water prior to cooking, so as to maximize the enjoyment of this pseudo-cereal.

Like other pseudo-cereals, quinoa contains significant amounts of all the essential amino acids. Quinoa is traditionally produced in South America in higher altitudes and cooler environments than Australia. The Rural Industries Research and Development Corporation (RIRDC) is currently undertaking trials of quinoa in Western Australia. The project aims to select suitable varieties and growing regions to produce quinoa in Australia.
