Abstract
A process for the extraction of oil from oats is disclosed. The process comprises extracting oil from comminuted oats with 2-propanol and separating the resultant 2-propanol solution from the de-oiled oats. Oat oil is recoverable from the 2-propanol solution. The 2-propanol may be in the form of an azeotropic mixture of 2-propanol and water. In a preferred embodiment the 2-propanol contains a minor amount e.g. 0.1- 1.0%, of hydrogen peroxide. The process is capable of producing a clear, lightly colored oil from oats. The oil is believed useful as a vegetable oil.
