Abstract
Official abstract text for this publication.
A method for separating steviol glycoside, including: a separating step 55 of performing a continuous liquid chromatography for continuously separating at least one type of steviol glycoside by allowing a liquid to be separated containing plural types of steviol glycosides to pass through a separating agent in which polyethylene imine is immobilized to a carrier.
First claim
Opening claim text (preview).
1 . A method for separating steviol glycoside, comprising: a separating step of performing a continuous liquid chromatography for continuously separating at least one type of steviol glycoside by allowing a liquid to be separated containing a plurality of types of steviol glycosides to pass through a separating agent in which polyethylene imine is immobilized to a carrier. 2 . The method for separating steviol glycoside according to claim 1 , wherein the carrier is a macromolecular carrier. 3 . The method for separating steviol glycoside according to claim 1 , wherein the liquid to be separated contains rebaudioside A as the steviol glycoside, and the rebaudioside A is separated from the liquid to be separated. 4 . The method for separating steviol glycoside according to claim 3 , wherein the liquid to be separated further contains stevioside as the steviol glycoside, and each of the rebaudioside A and the stevioside is separated from the liquid to be separated. 5 . The method for separating steviol glycoside according to claim 3 , wherein the liquid to be separated contains lower alcohol having carbon atoms of lower than or equal to 4 as a solvent. 6 . The method for separating steviol glycoside according to claim 1 , wherein the continuous liquid chromatography is performed by using a simulated moving bed type device. 7 . A method for producing rebaudioside A, comprising: a separating step of performing a continuous liquid chromatography for continuously separating rebaudioside A by allowing a liquid to be separated containing a plurality of types of steviol glycosides containing the rebaudioside A to pass through a separating agent in which polyethylene imine is supported on a carrier. 8 . A device for separating steviol glycoside, comprising: a plurality of filling portions filled with a separating agent in which polyethylene imine for separating a plurality of types of steviol glycosides contained in a liquid to be separated by a chromatography is supported on a carrier; a supply portion provided in each of the filling portions to supply each of the liquid to be separated and an eluent far extracting a separated liquid rich in at least one type of steviol glycoside in the liquid to be separated to the filling portion; and an extraction portion provided in each of the filling portions to extract the separated liquid from the filling portion.
