SAFETY OF VEGETABLE RAW MATERIALS USED IN FOOD SYSTEMS

Abstract

The developed fortified products contain ingredients that are widely studied for a strictly defined set of macro-and micro-components that are deficient for the human body. However, the presence of additional unregulated elements in the enriching raw materials is not fully studied. In this context, the issue of a comprehensive study of not only the nutritional value, but also the element composition of raw materials that increase the nutritional density of the enriched product is relevant. The aim of the research was to study the safety and chemical composition of plant raw materials used to increase the nutrient density of food systems. Freeze-dried ground apples produced by PJSC Sibirsky gostinets (Pskov region, Moglino village) and Brazil nut kernels produced by Comservice LLC (Moscow region, Mytishchi) were used as research objects. It is established that the studied plant materials are safe for human health in terms of their elemental composition and microbiological indicators. The study of food density showed that ground apples did not correspond to the declared levels of protein and fat by 45,2 and 96,2%, respectively. However, Apple powder has a relatively high content of mineral elements Mo, Na, Si, Ga, B, sugar, starch, dietary fiber and organic acids, Brazil nut kernels-Mg, Se, Cu, P, CA, Mn, Zn, Fe, Co, Ni, Al, protein and lipids.
