Abstract

In the modern food industry special attention is paid to improving the quality of functional products. The problem of food shortages has given way to its low nutrient composition. Regular imbalance in the intake of vitamins and trace elements can lead to the development of disorders in the body, called vitaminosis or micronutrientosis. Regional peculiarities of the food production area, the influence of anthropogenic factors on the environment, the quality of drinking water and others contribute to the emergence of an imbalance of elements. Diet correction can be used as a mechanism for regulating violations of the elemental status of the population. In this case, it is advisable to use fortified foods. One way to enrich and preserve the necessary component is to immobilize its colloidal structure on the surface of a biopolymeric carrier. Insoluble or gel-forming natural sorbents and carriers with a protein structure are most suitable for immobilization. These include: agar, pectin, chitosan, collagen, starch, cellulose, carbon, etc. An important criterion for selecting a carrier is low toxicity, solubility in the body, and the ability to provide a stable fixation of the dispersed phase. The choice of the immobilization method is important to increase the fixation of the introduced component and reduce the obstruction of its absorption in the body.
