Method for separating betaine |
摘要 |
The invention relates to a method for separating betaine from fermentation process solutions, vinasse and other sugar beet based solutions on a weakly acid cation exchange resin in H+-form in the chromatographic separation process. The present invention relates also to use of a weakly acid cation exchange resin in H+-form for the chromatographic separation of betaine. |

1. A method for chromatographic separation of betaine from a sugar beet based solution comprising betaine, polyols, and carboxylic acids, said method comprising adjusting the pH of the sugar beet based solution to below 5.1 and subjecting the resulting solution to chromatographic separation on a weakly acid cation exchange resin in H+-form, eluting betaine after polyols and carboxylic acids, and collecting a fraction enriched in betaine. |
