Abstract
A method of purifying cyclitols, particularly inositol, from mixtures including simple and complex carbohydrates begins by reducing the concentration of carbohydrates other than cyclitols to facilitate separation and crystallization of the cyclitol in high purity. Other carbohydrates can be removed or depleted from a mixture by adding a microorganism to the mixture which preferentially consumes carbohydrates but not cyclitol.
Claims11
A method of purifying cyclitols comprising:
- preparing a plant extract mixture containing at least one cyclitol and other carbohydrates;
- adding to said plant extract mixture a microorganism which consumes an alditol;
- and
- substantially reducing the concentration of an alditol in the plant extract mixture, whereby the concentration of said cyclitol or cyclitols is enhanced relative to the concentration of said alditol.
