Possibilities of the method of an X-ray fluorescence analysis when evaluating essential element concentrations in food raw materials of plant origin

Abstract

The population growth on the earth and the prospects for its increasing put forward a problem of providing clear drinking water to society and valuable fodder, food and energy resources on one of the first places every 25–30 years. The acuteness of the problem becomes more and more appreciable every year as mankind consumes the potential energy of the biosphere almost 10 times faster than its natural accumulation occurs by green plants during photosynthesis. Thus, the task of searching plant raw materials, which would become a source of biologically active substances and have positive influence on the health of animals and persons, is especially relevant today.
