Justification of selection of packaging material and packing method for preservation of vitamin-mineral concentrate quality

Abstract

In the production of quality food products, special attention must be paid to its packaging and storage. These process steps are especially important for products containing labile biologically active substances. In order to select packaging materials and packing method, an analysis of the scientific literature was conducted with the search query “packaging materials for foodstuffs” and “the effect of packaging on the preservation of vitamins during food storage” in the Google Scholar system. The article presents trends in the development and use of packaging materials, reflects the advantages and disadvantages of biopolymers, as well as prospects for improving the characteristics of packaging materials. As an example, for the choice of packaging material and packing method, data from Russian scientists based on packaging materials used in the Russian Federation is given. Storage of beef steaks in bags with reduced gas permeability under vacuum and a modified gas atmosphere with a reduced content of free space for 14 days contributes to the inhibition of bacteria. Storage of sterilized and ultra-pasteurized milk is preferably in bags of a three-word film filled with titanium dioxide, in comparison with glass packaging, due to a decrease in light transmission and a decrease in the rate of decomposition of vitamin C. It is preferable to store orange juice in packages of combined materials that exclude the presence of an air cushion, which positively affects the content of vitamin C. Based on the analysis of packaging materials used in the food industry and taking into account the humidity and chemical composition of the vitamin and mineral concentrate, it seems appropriate to use packaging materials made of polymer films with high light and gas impermeability, which can reduce the rate of destruction of vitamin C and other easily oxidized components and eliminate the use of ? -radiation, replacing it by evacuation. The use of edible films for vitamin and mineral concentrate as packaging materials remains open and requires more careful study.
