This process was developed to simultaneously deliver iron, iodine, folic acid, and vitamin B 12 for holistic prevention of anaemia and other risk factors for prenatal complications in vulnerable populations. Salt was chosen as the ‘vehicle’for the micronutrients because ‘doses’ of the micronutrients can be predicted. The process was based on a cold forming extrusion-based microencapsulation (for making premix) that ensures that added micronutrients are stable, indistinguishably mixed with salt, do not segregate, and do not cause changes to the sensory characteristics of salt and foods.
