What has long attracted people to this plant, apart from its size? It turns out that, in addition to the large above-ground part, the mulberry also has a branched root system: its rhizome is thick, fleshy, with numerous long roots. They are used in scientific and folk medicine. In autumn, rhizomes with roots are dug up, washed in cold water, cut into pieces (sometimes additionally cut lengthwise), dried for 2-3 days in the shade, and then dried in a well-ventilated room or in special dryers at a temperature not higher than 40 °C . In windy weather, rhizomes can be dried in the sun. The term of storage of raw materials is 3 years.
Rhizomes and roots contain up to 44% of inulin polysaccharide and other substances. As a result of hydrolysis under the action of acids, inulin turns into sugar – fructose, which is 1.5-2 times sweeter than ordinary sugar (sucrose). The process of obtaining fructose from rhizomes is rather complicated and time-consuming.
