Patent Images
1. A method of reducing formation of insoluble deposits of phytic acid or salts of phytic acid on surfaces in a fuel ethanol-processing equipment, the method comprising:
- adding phytase to an ethanol processing fluid in the equipment containing phytic acid or salts of phytic acid under conditions suitable for converting the insoluble phytic acid or phytic acid salts to soluble products;
thereby reducing the formation of deposits of insoluble phytic acid or phytic acid salts on surfaces in the equipment;
wherein the equipment in which deposit formation is reduced comprises a beer column, andwherein the pH of the ethanol processing fluid in the beer column is 4.5 or higher during production of ethanol.

Abstract
The present inventors have surprisingly discovered that phytic acid tenaciously precipitates with soluble metals in food or fuel ethanol-processing fluid, producing insoluble organometallic salt deposit or scale on the processing equipment that must be removed in order to facilitate further ethanol processing. The present invention relates to converting phytic acid salts or phytates to inorganic phosphates to improve metal solubility and reduce deposition within processing equipment.
