Abstract
Blown corn stillage oils and methods for making blown corn stillage oils are disclosed. In one aspect the corn stillage oils are stripped to reduce the acid value of the resulting blown, stripped corn stillage oil. The method includes heating a corn stillage oil to a temperature of at least 90° C., and passing air through the heated oil to produce a blown corn stillage oil having a viscosity of at least 50 cSt at 40° C. In one aspect, the blown corn stillage oil is stripped to reduce the acid value of the blown, stripped corn stillage oil to 5 mg KOH/gram or less.
