Cassava
Cassava (*Manihot esculenta*) is a woody tropical shrub grown for its starchy underground roots, which are eaten as a staple food and processed into products such as flour and tapioca.
Cassava is a woody tropical shrub grown for its starchy underground roots, a staple food in many regions. It is native to South America but now cultivated widely in tropical and subtropical areas.
What it is
Cassava (*Manihot esculenta*) is a perennial shrub in the spurge family, valued for its edible, starch-rich storage roots. It is grown mainly as an annual crop and is known by names like manioc, yuca, and mandioca.
Why it matters
The roots are a major source of carbohydrates and are processed into cassava flour and tapioca. Cassava is important for food security because it grows well in poor soils and drier conditions, and is cultivated across Africa, Asia, and the tropical Americas.
Key details
Raw cassava contains cyanogenic compounds and is poisonous until properly processed. Peeling, soaking, fermentation, and cooking remove the hazard. In Canada, cassava products like flour and tapioca are used in multicultural cuisine and food manufacturing.
In short
- Cassava is a starchy root crop and a major tropical staple.
- It must be cooked or processed to remove natural toxins.
- Cassava flour and tapioca are common gluten-free products.
- It is grown in poor soils and drier conditions, aiding food security.
Cassava is relevant in Canada mainly through global food trade and multicultural cuisine, where cassava flour, tapioca, and imported cassava products are used in cooking and food manufacturing.
