# Methods of washing a grain particle material and/or a stillage composition, and related systems and biorefineries

## Abstract

Methods and systems for washing grain particle material and/or a stillage composition. Washing can be used to separate components such as one or more mycotoxins from the grain particle material and/or stillage composition. The methods include providing an aqueous composition that includes grain particle material or a stillage composition, and an aqueous liquid. The aqueous composition is separated into a solids fraction and at least one liquid fraction so that at least a portion of the components are separated from the solids fraction into the liquid fraction.
