There are three main technologies available to produce fortified rice. They are: coating, extrusion and dusting. In the coating method, the nutrient (vitamin or mineral mix) is combined with ingredients such as waxes and gums. It is then sprayed on the surface of rice grains in several layers. This is then blended with polished rice at about a ratio of 1:100. In dusting, micronutrients in the form of ne particles are blended with bulk rice. This method makes use of the electrostatic forces between the rice’s surface and the micronutrients.
