Abstract:
1. A process for producing inositol from plant materials comprising the steps of: a) providing a plant material comprising a neutral soluble sugar and at least one of a phytate or a phytin; b) providing an aqueous slurry of said plant material from step a), wherein said aqueous slurry of said plant material comprises said neutral soluble sugar of said plant material and said at least one of a phytate or a phytin of said plant material; c) conducting a partial hydrolysis by treating said aqueous slurry of said plant material resulting from step b) with an enzyme product enriched in phytase enzyme to partially hydrolyze said at least one of a phytate or a phytin to produce a partially hydrolyzed slurry comprising a mixture of inositol phosphates which are negatively charged, and wherein said plant material is a main source of the phytate or phytin which is partially hydrolyzed during said step of a partial hydrolysis; d) separating said partially hydrolyzed slurry of said plant material resulting from step c) to produce a water soluble fraction and a water-insoluble fraction, wherein said water soluble fraction comprises inositol phosphates which are negatively charged, as well as said neutral soluble sugar of said plant material; e) separating said water soluble fraction resulting from step d) into a first ionic fraction comprising inositol phosphates which are negatively charged and a first neutral fraction comprising said neutral soluble sugar of said plant material; f) conducting a hydrolysis of said inositol phosphates of said first ionic fraction resulting from step e) to produce inositol and an anionic fraction; and g) separating said inositol from said anionic fraction resulting from step f.
