Knowra Cassava Cassava Cassava is a tropical shrub cultivated for its starchy storage roots. Its roots contain cyanogenic compounds and must be properly processed or cooked before eating.
Manihot esculenta : The botanical species cultivated as cassava, with varieties grown for food and other uses. This is cassava’s scientific species name and the source of its cultivated forms.
Cassava processing : A set of preparation methods that reduce cassava’s cyanogenic compounds and turn roots into food products. Peeling, grating, soaking, fermenting, drying, or cooking can make roots safer to eat.
Cassava cultivation : The agricultural production of cassava, including planting, crop care, harvesting, and variety selection. Cultivation practices determine root yield, harvest timing, and crop resilience.
Amazonia : The vast tropical region drained by the Amazon River and its tributaries. Cassava was domesticated in South America, with Amazonia central to its early cultivation.
Sweet potato : A crop plant cultivated for its edible, carbohydrate-rich storage roots. Both crops produce starchy roots, but sweet potato belongs to a different plant family and generally needs no cyanide detoxification.
Storage root : A plant root enlarged to store carbohydrates or other reserves for later growth. Cassava’s edible crop is an enlarged root that stores starch.
Cassava fermentation : The microbial fermentation of cassava roots or mash to make foods such as gari and fufu. Fermentation contributes to flavor and can help reduce cyanogenic compounds.
Cassava as a staple food : The use of cassava roots and derived products as major sources of dietary energy. Cassava feeds hundreds of millions of people, especially in tropical regions.
Plant domestication : The process by which people alter wild plants through cultivation and selection over generations. Human selection transformed cassava into a crop with larger, more useful roots.
Yam : A common name for several edible tubers of the genus Dioscorea. Yams are often compared with cassava as tropical staples, though their plant structures and processing needs differ.
