Phytate and/or phytin and/or phytic acid in an aqueous slurry of plant mateiral is partially hydrolyzed by incubating the slurry with an enzyme product enriched in phytase. The soluble fraction of the slurry is separated into anionic and neutral fractions. The anionic fraction is then hydrolyzed further, and the hydrolyzate is separated into second ionic and neutral fractions. The second neutral fraction thus obtained is rich in inositol, and does not contain significant quantities of other sugars which would be hard to separate from it.
Un phytate et/ou de la phytine et/ou de l'acide phytique dans une bouillie aqueuse d'un matériau végétal est partiellement hydrolysé en incubant la bouillie avec un produit enzymatique enrichie en phytase. La fraction soluble de la bouillie est séparée en fractions anionique et neutre. La fraction anionique est ensuite hydrolysée, et l'hydrolysat est séparé en de secondes fractions ionique et neutre. La seconde fraction neutre ainsi obtenue est riche en inositol, et ne contient pas de quantités significatives d'autres sucres qui seraient difficiles à séparer.
