1. A method of recovering a byproduct of a grain oil composition feedstock from distillers corn oil, the method comprising:
recovering whole stillage from distillation of a grain feedstock;
separating the whole stillage into wet cake and thin stillage;
processing the thin stillage in a separator to recover a grain oil composition feedstock;
cooling the grain oil composition feedstock to form a temperature adjusted grain oil composition feedstock including a grain oil product and a byproduct of the grain oil composition feedstock;
recovering the byproduct of the grain oil composition feedstock; and
wherein the byproduct of the grain oil composition feedstock is any fraction or phase separated from the temperature adjusted grain oil composition feedstock other than the grain oil product.
