FIELD: chemistry. ^ SUBSTANCE: invention relates to a method of extracting betaine from a solution obtained from sugar beet. The method for chromatographic extraction of betaine from a solution obtained from sugar beet, which contains betaine, polyols and carboxylic acids, involves changing the pH of the solution to a certain value, chromatographic separation of the obtained solution on a weakly acidic cation-exchange resin in H+ form, elution of betaine after polyols and carboxylic acids, and collection of fractions rich in betaine; use of a weakly acidic cation-exchange resin in H+ form for chromatographic extraction of betaine from a solution obtained from sugar beet. ^ EFFECT: method provides efficient extraction of a pure betaine fraction. ^ 42 cl, 6 dwg, 1 tbl, 7 ex |
