Abstract

A method for using a thermostable phytase for eliminating or reducing phytic acid or salts of phytic acid in an alcohol production process is disclosed. The phytase can be added anywhere in the alcohol production process including a feedstock, a hammer mill, a slurry tank, a jet cooker, a liquefaction, a mash cooker, a fermentation, a beer, a distillation system, a whole stillage, a centrifuge, a thin stillage, an evaporator, a condensate, a syrup, a wet grain, a drum dryer, a distillers dried grain, distillers solubles, distillers wet grain, condensed distillers solubles distillers dried grains with solubles a molecular sieves, or any combination thereof. The alcohol production process can be in an ethanol production plant; a spirit or a drinkable alcohol production plant; or a fuel ethanol plant.
