Selection of biopolymer carriers for immobilization of essential elements on their surface

Abstract

Optimization of food recipes, in order to increase their nutritional and biological value, remains relevant in the modern world. In regions with an identified imbalance of essential elements, correction of the diet of the population is necessary. One of the most effective methods is the enrichment of products with immobilized colloidal structures of the necessary elements on the surface of biopolymer carriers. Sorption immobilization is more often used in the food industry, due to its simplicity, cheapness and efficiency, as well as due to the weak influence of the carrier on the catalytic ability of the dispersed phase. As carriers suitable for the immobilization of elements, first of all, insoluble or gel-forming natural sorbents are suitable. These include: agar, pectin, chitosan, collagen, starch, cellulose, coal and others. The article lists the most suitable methods of immobilization, selected carriers. In order to minimize the negative impact of the dispersion medium, the use of a multicomponent carrier is proposed. This applies to both hydrophobic and hydrophilic compounds. It is possible to combine biopolymers with coal, in order to increase the sorption capacity and antimicrobial properties of the finished surface. In the case of pectin and agar, the thermal reversibility of the carrier can be used to simplify the storage of the finished immobilized structure. Currently, technologies for the immobilization of essential elements on the surface of biopolymer carriers are being developed in order to optimize recipes for culinary products and dishes for the food industry.
