The addition of micronutrients to food is known as a fortification.
The practice can be carried out by public health officials or food manufacturers with the goal of reducing the number of people with nutritional deficiencies in a population.
Fortification can be accomplished in three ways: biofortification, at-home fortification, and commercial and industrial fortification.
Zinc, iron, folate, vitamin A, vitamin D, calcium, and other micronutrients are employed as fortifiers.
The bioavailability and stability of a nutrient can be determined by selecting the right fortifier and processing methods.
In addition, given the variances in food consumption, the levels of fortified food must be addressed in order to ensure safety.
