Dietary fiber obtained from amaranth (Amaranthus cruentus) grain by differential milling

Specific differential milling of amaranth (Amaranthus spp.) yields three different granulometric fractions, which are classified according to their composition and properties. They are a high-fiber fraction, a high-protein fraction and a high-starch semolina. The high-fiber fraction can be improved by pneumatic classification until a product with 63.9% insoluble fiber and 6.86 soluble fiber contents is obtained.
