Claims (4)

1. A method of producing an inulin-pectin concentrate in powder for medical purposes by separating juice from Jerusalem artichoke tubers, obtaining aqueous extracts of inulin from raw materials, extracting pectins with an aqueous acid solution, crystallizing and precipitating them, characterized in that, in order to obtain an inulin-pectin concentrate in powder for oral administration in the treatment of diabetes mellitus, development of non-waste technology for the processing of tubers to obtain the final product, extraction of fractions of inulin and pectins from sy rd given batch (tuber or tuber powder) is carried out sequentially, first inulin fraction, and then fractions of pectin, and their subsequent separation, drying at 70 ^o C, combining, milling, and give the final product inulin, pectin concentrate powder ratio inulin, pectin 2 : 1 in concentrate powder. 2. The method according to p. 1, characterized in that the inulin fractions are obtained from juice evaporated in a water bath or under vacuum at 70 ^{° C.} for 1/2 part, crystallization at 3-4 ^{° C.} for 5 days, and also aqueous extracts of pomace obtained at 75 ^° C, stripped to 1/10 part, crystallization after addition of 96% ethanol 1: 1 at 4-5 ^° C for 5 days, followed by separation and drying of the intermediate of the inulin fraction. 3. The method according to p. 1, characterized in that after the extraction of inulin, a fraction of pectins is obtained from the remaining squeezes by extraction with an aqueous solution of citric acid with a pH of 1.8-2.0 at 80 ^{° C.} , evaporation to 1/10 of the acidic extracts at 70 ^o C, precipitation of pectins with 96% ethanol in a ratio of 1: 3, separation of pectins, washing the precipitate with 70%, then 96% ethanol, separation, drying of the intermediate product of the pectin fraction, then combining the intermediate products of inulin and pectins, grinding, additional drying powder to a residual moisture content of 9% and obtain the final product of inulin-pectin concentrate in powder with an average yield of dry product of 13.4% based on dry tubers of this batch. 4. The method according to PP. 1-3, characterized in that the remaining pulp is dried at 80 ^o C, grind, get an additional product for food purposes, containing dietary fiber and the remaining amount of citric acid, with a dry product yield of 11% based on dry tubers of this batch, which allows offer non-waste environmentally friendly technology for processing Jerusalem artichoke tubers.
