This review presents the information about the chemical structure and biological properties of fructanes. The presented results of individual influence research of various fructanes on the representatives of intestinal microflora of the laboratory animals and people. However, there is not enough information about fructanes metabolism in the body of farm animals, including ruminants, and their possible effect on the digestive processes of these animals. The article deals with the importance of fructanes as components of humans and animals diet. It was found out that they affect the metabolism and physiological state of the microorganisms, but their increased numbers in the gute an causo negative effects. Fructooligosaccharides and inulin stimulate growth of the intestine bifid bacteria. Ne­vertheless, strains of bifid bacteria of animal origin grow on the medium with inulin faster compared to strains isolated from human. The study of influence of orally injected fructooligosaccharides made it possible to detect the stimulating effect of su­gars on growth of the bifid bacteria in the intestine of laboratory animals and human. However, these data are not consistent with the effect of fructooligosaccharides in other types of bacteria. The hypothesis was proposed that consumption of fructanes with further increase of the bifid bacteria causes a reduction of clostridia. Therefore analysis of the impact fructanes on other representatives of the intestinal flora of animals shuld be studied.
