Abstract
The present disclosure relates methods and systems for refining grain oil compositions using water, and related compositions produced therefrom. The present disclosure also relates to methods of using said compositions. The present disclosure also relates to methods of using grain oil derived from a fermentation product in an anti-foam composition. The present disclosure further relates to stabilized emulsion products and methods for forming thereof.
Claims10
A method of separating and stabilizing a grain oil composition to provide a homogenous emulsion, the method comprising:
- fermenting a grain feedstock to form a fermented product including an oil fraction and an aqueous portion, and separating a thin stillage from the fermented product and processing the thin stillage to form the grain oil composition, wherein the processing includes concentrating the thin stillage into a syrup, separating the syrup into a defatted syrup and an emulsion, and treating the emulsion to form the grain oil composition, and wherein the treating includes adjusting the pH of the emulsion to break the emulsion into a defatted emulsion and the grain oil composition;
- combining the grain oil composition with additional water to form an oil and water mixture;
- exposing the oil and water mixture to a temperature and for a time effective for the oil and water mixture to form at least an oil phase and an emulsion phase;
- separating at least a portion of the oil phase from the emulsion phase to form a heavy emulsion phase;
- and
- treating the heavy emulsion phase with an alkali or alkaline metal base to form the homogeneous emulsion.
