Abstract
A process of recovering inositol from hydrolyzates of crude insoluble salts of phytic acid from the group consisting of calcium phytate, magnesium phytate, mixed calcium-magnesium phytate and mixtures thereof which have been obtained from cereal grain steep liquor is characterized by the steps of adjusting the pH of hydrolyzate to about 9 with lime, separating out the insoluble impurities, concentrating the clarified liquor, adding thereto methyl alcohol, ethyl alcohol, isopropyl alcohol or mixture thereof, allowing crystals of inositol to form and separating the crystals. Where the inositol concentration in the neutralized hydrolyzate is low the liquor is preferably dried and the residue dissolved in hot aqueous alcohol and the inositol allowed to crystallize. In preparing the starting materials calcium phytate may be obtained by adding lime to steep-water, crude magnesium phytate by adding magnesium hydroxide and crude mixed calcium-magnesium phytate by adding sodium or potassium hydroxide to steep-water. The phytate is washed and hydrolysed to inositol and calcium phosphate by heating with water. The adjustment of the hydrolyzate to about pH 9 is made in one step or two steps in accordance with the process of Specification 686,396 and the mixture is filtered, the filtrate concentrated, isopropyl alcohol added and inositol crystallizes out on cooling. Yields and purities of inositol obtained using the three alcohols are summarized in a table. Specification 601,273 also is referred to.
