Method for obtaining phytin

摘要

A phytin-containing solution such as corn steep liquor, acid extract of rice bran is treated with an anion exchange resin with phytin adsorption. The phytin is then separated from the resin by alkali-elution, then the phytin thus recovered is further subjected to the treatment of hydrolysis under pressure, phosphate removement, purifying, etc. to prepare inositol. Alternatively, the recovered phytin is further subjected to the treatment of desalting, purfiying, etc. to prepare phytic acid.
