Claims20
A method of refining a grain oil composition feedstock to provide a grain oil product, wherein the method comprises:
- combining the grain oil composition feedstock with water to form an oil-water mixture, wherein the grain oil composition comprises an impurity component, and wherein the oil-water mixture does not include chelating agent in an amount to aid in removal of metals and metal compounds from the grain oil composition feedstock;
- exposing the oil-water mixture to a temperature in the range from 0° C. to 50° C. for a time period at least until the oil-water mixture forms at least an oil phase and an emulsion phase;
- and
- separating at least a portion of the oil phase from the emulsion phase to form the grain oil product, wherein an amount of the impurity component in the emulsion phase is greater than an amount of the impurity component in the grain oil product.
A method of refining a grain oil composition feedstock to provide a grain oil product, wherein the method comprises:
- combining the grain oil composition feedstock with water to form an oil-water mixture having water in an amount of 3-40% based on the total volume of the oil-water mixture (v/v), wherein the grain oil composition comprises an impurity component, wherein the impurity component comprises an element component, wherein the element component comprises at least one element chosen from calcium, phosphorus, potassium, sodium, magnesium and combinations thereof;
- and wherein the oil-water mixture does not include chelating agent in an amount to aid in removal of metals and metal compounds from the grain oil composition feedstock,
- exposing the oil-water mixture to a temperature for a time period at least until the oil-water mixture forms at least an oil phase and an emulsion phase;
- and
- separating at least a portion of the oil phase from the emulsion phase to form the grain oil product, wherein an amount of the impurity component in the emulsion phase is greater than an amount of the impurity component in the grain oil product, wherein the grain oil product comprises element component in an amount from 0-20 ppm.
A method of refining a grain oil composition feedstock to provide a grain oil product, wherein the method comprises:
- combining the grain oil composition feedstock with water to form an oil-water mixture, wherein the grain oil composition comprises an impurity component, wherein the impurity component comprises an element component, wherein the element component comprises at least one element chosen from calcium, phosphorus, potassium, sodium, magnesium and combinations thereof;
- and wherein the oil-water mixture does not include chelating agent in an amount to aid in removal of metals and metal compounds from the grain oil composition feedstock;
- forming at least an oil phase and an emulsion phase from the oil-water mixture;
- separating at least a portion of the oil phase from the emulsion phase to form the grain oil product, wherein an amount of the impurity component in the emulsion phase is greater than an amount of the impurity component in the grain oil product;
- and
- filtering the grain oil product to form a permeate comprising a filtered grain oil product, wherein the filter grain oil product comprises element component in an amount from 0-20 ppm.
A method of refining a grain oil composition feedstock to provide a grain oil product, wherein the method comprises:

- exposing the oil-water mixture to a temperature for a time period at least until the oil-water mixture forms at least an oil phase and an emulsion phase;
- and
- filtering at least a portion of the oil phase from the emulsion phase to form a permeate comprising a filtered grain oil product, wherein an amount of the impurity component in the emulsion phase is greater than an amount of the impurity component in the filtered grain oil product;
- and
- wherein the oil-water mixture does not include chelating agent in an amount to aid in removal of metals and metal compounds from the grain oil composition feedstock.
