Zinc fortification of food

There is a wide range of nutrients and other ingredients that might be used in food manufacturing, including minerals. Their addition to foods is regulated by different national regulations. Food industry producers add minerals to foods for a number of purposes such as restoring their content where this has been reduced during manufacturing, storage or handling procedures or improving the overall nutritional quality of diets and public health. An adequate diet can provide all necessary nutrients. However, population-based surveys show that this ideal situation is being achieved neither for all minerals nor by all groups of the population. We gave an overview of the zinc fortification in food because zinc is known to be involved in the activity of numerous enzymes in most major metabolic pathways. Zn is necessary for a wide range of biochemical and immunological functions. As a result, a number of functions in the body are affected by Zn deficiency. Approximately 1/3 of the world's population is suffering from zinc deficiency. Zinc fortification of foods is considered as a potential solution to overcome the malnutrition of this mineral. Zn fortification is a process of increasing accumulation and bioavailability of zinc in edible portions of dietary source. Different food vehicles have been employed for Zn fortification and various zinc salts approved for fortification differ in their technological properties, bioavailability, side effects and costs.
