Abstract
A process is described for the separation of at least one inositol from a carob extract. The carob extract is filtered and demineralized, and has a Brix value greater than 60 and a pinitol content of 5 to 25 wt %. The carob extract is subjected to chromatographic separation which involves at least one passage on a chromatographic resin. This produces an aqueous solution comprising 35 to 70 wt % pinitol and a Brix value of 20 or lower. The aqueous solution is then purified to obtain a purified aqueous solution having a pinitol content of more than 55%.
Claims12
A process for the separation of at least one inositol from a carob extract comprising:
- a) providing a filtered and demineralised carob extract having a Brix value of greater than 60 and a pinitol content, in weight percent based on the weight of the extract, from 5 to 25%;
- b) subjecting the carob extract to a chromatographic separation of the pinitol by at least one passage on a chromatographic resin to obtain an aqueous solution having a pinitol content, in weight percent based on the total weight of the solution, from 35 to 70%, and which has a Brix value of 20 or lower;
- and
- c) purifying the aqueous solution to obtain a purified aqueous solution having a pinitol content, in weight percent based on the total weight of the solution, of more than 55%.
