专利汇可以提供Production of phytic acid专利检索,专利查询,专利分析的服务。并且PURPOSE: Phytic acid is added to an aqueous suspension containing phytin to effect extraction of phytin, then the extract is purified by the membrane separation and treated with a cation-exchange resin to obtain phytic acid through a reduced-step process with the concentration process omitted.
CONSTITUTION: A substance containing phytin such as cereal or seeds is suspended in water, the suspension is combined with phytic acid to extract phytin at a pH lower than 4, preferably 2W3.5. Then, the resultant extract containing phytin and phytic acid is purified by the membrane separation method, namely pretreatment with an ultrafiltration membrane, then a reverse- osmotic membrane. Then, the purified extract is treated with a cation-exchange resin and, when needed, an anion-exchange resin to give phytic acid. The above- stated extract is preferably decolorized by treatment with activated carbon and removed undissolving suspension beforehand.
