Milk in its natural form is almost unique as a balanced source of
man's dietary need. The various steps in processing and storage have a
measurable impact on some specific nutrients.
Fortification is defined as the practice of deliberately increasing the
content of an essential micronutrients such as essential vitamins and
minerals to food. The fortification of food products has been practiced
for more than 80 years.
The micronutrients which are commonly used in the fortification of the food products such as milk and its products are:
• Vitamins and co-vitamins
• Essential minerals
• Essential fatty acids
• Essential amino acids
• Phytonutrients
• Enzymes
Vitamins are compounds which play a role as cofactors in the body.
Fermented milk products such as yogurt can be thought as vitamin
sources. Vitamin concentrates with vitamins A and D are used for
fortification of fluid milk.
Vitamin fortification has a long history in fluid milk in the United
States to reduce rickets in children, and the FDA mandated in the 1990s
that fortified fluid milks must be within 100% to 150% of label claims
to address documented variability in vitamin amounts.
Iron-fortified yogurt has a relatively high iron bioavailability. Iron
fortification of milk and dairy product is considered as a potential
approach to prevent the iron deficiency disorder , since dairy foods are
an important part of the daily diet in most parts of the world.
Iron fortification of milk or dairy products induces several bio
physicochemical modifications with important consequences. Iron
fortification of food is regarded as the most cost-effective method for
reducing the prevalence of nutritional iron deficiency. Iron deficiency
induces anemia, alters mental development, decreases immunity, impairs
cognitive scores in children and leads to poor pregnancy outcome.
