摘要: ABSTRACT A process for purifying lactulose from other carbohydrates, in particular lactose and galactose, by passing a syrup through one or more columns containing bifunctionalised boron resin of the type: (I) which ? is polyacrylic polystyrene polymer matrix R, R1, R2, R3, X are as defined text. By solution carbohydrate impurities matrix, selectively retained subsequently released elution with an acid solution. The small quantity galactose may still be contained lactulose-enriched can removed said retains galactose.
