In rice fortification, coating is a technology to make fortified kernels through which rice kernels are coated with a fortificant premix plus ingredients such as waxes and gums. The micronutrients are sprayed onto the rice grain’s surface. The coated rice kernels are blended with non-fortified rice in a ratio between 0.5 and 2% (or 1:50 to 1:200).
