Abstract:
A method of obtaining pinitol from a pinitol-containing carob extract having the composition:Saccharose55-75%â€‚Fructose7-15%Glucose7-16%Other sugars0.5-3%â€‰â€ƒCyclitols4-14%Organic and inorganic impurities0.5-2%â€‰â€ƒwherein the percentages are expressed in weight of dry matter, the method consisting of extracting carob to obtain said extract inverting the saccharose contained in the extract to fructose and glucose to obtain a syrup, subjecting the syrup to chromatographic separation of the pinitol from the sugars contained in the syrup, employing a strong cationic exchange resin to obtain a solution of pinitol in water containing 90% or greater pinitol content, based on dry weight, and recovering the separated pinitol.
