What Is Cassava Flour?
Cassava flour is derived from the root of the cassava plant, also known as Manihot esculenta, yuca, or manioc. It serves as a gluten-free, grain-free alternative to wheat flour with a reputation for being versatile in various recipes.
Origin and Cultivation
Cassava originates from South America, but it has spread to Africa and Asia, where it is now a staple food for millions of people. The plant thrives in tropical climates where other crops may struggle to survive. The cassava used for flour production typically grows for six to 18 months before harvesting.
Cultivation Characteristics:
Climate: Prefers tropical, warm conditions
Soil: Tolerant of low-nutrient soils
Harvesting Period: 6 to 18 months after planting
Processing Cassava Into Flour
To transform the starchy cassava root into flour, the process involves peeling, washing, and grating the yuca. The grated pulp is then dehydrated and finely milled. Unlike tapioca flour, which is extracted starch, cassava flour includes the whole root, retaining more fiber.
Processing Steps:
Peel and Wash: Remove the skin and rinse the root.
Grate: Pulverize the root to a pulp.
Dehydrate: Dry the pulp to reduce moisture content.
Mill: Grind the dried pulp into a fine powder.
Cassava flour does not contain gluten, making it a suitable option for those with celiac disease or gluten sensitivities. It's also distinct from tapioca flour, as the latter is starch extracted from the cassava root, used primarily as a thickening agent.
