METHOD FOR PRODUCING INULIN-COTAINING EXTRACT AND SYRUP FROM TOPINAMBOUR TUBERS (HELIANTHUS TUBEROSUS)

The present invention pertains to methods for obtaining and using biologically active concentrates from raw materials of plant origin, particularly, to production of inulin-containing extracts and syrups from topinambour tubers (Helianthus tuberosus). The offered method for production of inulin-containing extracts and syrups from finely divided topinambour tubers characterized in that for extraction of tubers are used dried and roasted particles of topinambour tubers that contain products of Mayar-reaction and caramelization as source for taste, color and aroma of formed extracts. The extraction could be provided using water at a temperature from 20 to 100 centigrade during 15 to 60 min. and concentration of particles suspension from 5 to 20 percent calculated to dry matter, by further separation of solid fraction and pasteurization of clear fraction. For obtaining long-time storage product, the extract of topinambour tubers could be evaporated in vacuum apparatus at a temperature from 60 to 90 centigrade achieving dry matter content in syrup from 60 to 70 percent. For increasing content of Mayar-reaction products in syrup, there is offered to make evaporation at an atmospheric pressure.
