Methods for the preparation and determination of inulin and technological parameters of jerusalem artichoke Helianthus tuberosus L

Abstract

Inulin is a polysaccharide of plant origin, soluble dietary fiber is considered a prebiotic. It is not digested by digestive enzymes, the intestinal microflora is completely destroyed and promotes the reproduction of beneficial bifidobacteria, suppressing the effects of harmful pathogenic bacteria. Inulin is a polypructosan that can be obtained as an amorphous powder and crystals, easily soluble in hot water and difficult to dissolve in cold water. The most promising source of flora of Kazakhstan for inulin is the soil pear Helianthus tuberosus L. It belongs to the group of available medicinal plants. It is found in almost all regions of Kazakhstan. In this work, the methods of inulin isolation from the composition of the soil pear Helianthus tuberosus, a medicinal plant of Kazakhstan, and indicators of technological parameters (specific, bulk, bulk masses and porosity) are determined. The quantitative determination of inulin was carried out using a spectrophotometric method.
