Fortifying rice
Rice coating, the technology involves the coating of ordinary rice with an alcoholic solution of ferrous sulfate and a suitable coating mixture to produce a premix, which is then mixed with ordinary rice at a predifined dilution to produce iron fortified rice.
Extruded rice, the technology involves the extrusion of a mixture of rice flour & mineral-vitamin-premix to produce a rice-kernel-like. The highly mineral-vitamin concentrated kernel will be then mixed with normal rice at a predefined ratio.
A Coeficient of Variation should be calculated to ensure that mineral and vitamins are homogeneously distributed in the finished product.
