ABSTRACT:
Protein and phosphorous free phytin is recovered from raw materials containing phytin by a process whereby the raw material is treated with an aqueous acid solution having a pH of about 1 to obtain a filtrate from which the phytin is precipitated by adding sufficient of a solution of bicarbonate ions to produce a pH of 7-8. In this way, phosphorous ions remain in solution while the phytin is precipitated out. The subsequently recovered precipitated phytin is again dissolved in a mineral acid and then saturated with a denaturating agent such as sulfur dioxide, ether or formaldehyde to thereby eliminate protein from the solution. Upon the addition of sufficient alkaline agent, the phytin is again precipitated and recovered in its purified form.
