| description | The invention relates to a process for the recovery of alpha -hydroxy- and alpha -amino-carboxylic acids from sugary media containing them. According to the process of the invention: in a first phase, the mixture from which it is proposed to recover the alpha -hydroxy- or alpha -amino-carboxylic acid and which contains the latter in the form of its calcium salt is contacted with a cationic resin in the calcium form for a sufficient time to reach optimal adsorption of said calcium salt and then, in a second phase, the previously saturated resin is eluted by resorting to water. The process according to the invention enables the quantitative production of a pure calcium salt. |
