METHOD FOR PRODUCTION OF INULIN-CONTAINING SOLUTION FROM GIRASOL, INULIN PRODUCTION METHOD AND METHOD FOR PRODUCTION OF FRUCTOOLIGOSACCHARIDES BASED ON SUCH SOLUTION

摘要

FIELD: food industry.;SUBSTANCE: method for production of an inulin-containing solution from girasol includes tubers washing and cutting into chip-shaped slices, the latter drying and grinding and production of a suspension by way of mixing the produced flour and water. Fructosans are extracted from the suspension with the solution purified after extraction. The purified solution is cooked till the dry substances content is equal to 42-45%. Additionally proposed is an inulin-production method according whereto the purified and boiled out inulin-containing solution is passed through nanofilters with attenuation threshold equal to first 5000 Da and then - 6000 Da with separation of a solution containing inulin with molecular weight equal to 5000 - 6000 Da. The produced inulin solution undergoes crystallisation. Sedimented inulin crystals are mixed with the initial inulin-containing solution and undergo drying. Additionally one proposes fructooligosaccharides production method.;EFFECT: inventions group allows to enhance the ready products quality and yield.;4 cl, 3 dwg, 3 ex
