FIELD: chemistry.SUBSTANCE: invention relates to biotechnology. Disclosed is a method of producing ?-cyclodextrin. The method includes preparing a suspension of maltodextrin, carrying out a ring closure process using a CGTase enzyme preparation in the presence of a trichloroethylene complexant. Further, the method includes removing the complexant by boiling, purifying the obtained product with activated carbon, separating the activated carbon by filtering and evaporating the syrup and crystallisation thereof while stirring and lowering the temperature. Finally, the method includes centrifuging and washing ?-cyclodextrin crystals with cold water, drying and packaging.EFFECT: invention can be used to produce cyclic complexing agents, particularly ?-cyclodextrin.2 dwg |
