Abstract:
Micronutrient deficiency is very burning issue in the recent era especially in the developing contraries. These are required to only minute quantity in the body. inadequacy of these minerals and vitamins develops devastating issue in the whole world. Pakistan is the developing country and it faces the problem of micronutrients imbalance in every age group. To overcome this zinc deficiency in Pakistani peoples different fortification strategies are used. In Pakistan 54% pregnant women’s, 37.2% babies, 62 % peoples are zinc deficient and due to this reason they are more prone to different vulnerable diseases as zinc deficiency creates the loss in the immune functions and stunted growth. Zinc participates in a wide variety of metabolic processes including carbohydrate, lipid, protein and nucleic acid synthesis or degradation. Zinc deficiency affects many organ systems, including the integumentary, gastrointestinal, central nervous system, immune, skeletal, and reproductive systems. Zinc deficiency results in dysfunction of both humoral and cell-mediated immunity and increases the susceptibility to infection. Supplementation of zinc has been shown to reduce the incidence of infection as well as cellular damage from increased oxidative stress. One of the best and economical methods to meet the daily requirement of peoples, zinc employed on fruits through edible coatings and films. Edible coating is the best way to implication of different micronutrients and additives on the different food commodities. For this purpose to overcome the zinc deficiency different zinc salts (zinc sulfate and zinc chloride) are used at specific concentration in combination with different edible coatings (chitosan, alginate and soy protein). Edible films and coatings have received considerable attention in recent years because of their advantages including use as edible packaging materials over synthetic films. This could contribute to the reduction of environmental pollution. By functioning as barriers, such edible films and coatings can feasibly reduce the complexity and thus improve the recyclability of packaging materials, compared to the more traditional non-environmental friendly packaging materials, and may be able to substitute such synthetic polymer films. The objective of this review is to provide a comprehensive knowledge of zinc fortified edible coatings by providing descriptions of suitable materials, reviewing their properties and describing methods of their applications and potential uses.
