Abstract of the Disclosure There is disclosed a process for extracting particles of oleaginous seed material with aqueous alcohol solutions, wherein displacement of dilute alcohol in the flakes is completed by concentrated alcohol at or near the boiling temperature thereof. In one embodiment of the present invention, the oleaginous seed material is sequentially extracted in five steps, comprising: contact with relatively cool and dilute aqueous alcohol to remove some or all of the alcohol-soluble carbohydrates and non-oil lipids; contact with relatively cool and concentrated alcohol to displace dilute alcohol; contact with concentrated alcohol at or near the boiling point to complete displacement of dilute alcohol and to initiate oil extraction; contact with undistilled, recycled concentrated alcohol at or near the boiling point to partially remove oil; and contact with distilled concentrated alcohol at or near the boiling point to complete oil removal; followed by desolventizing of the residual solids to yield a protein concentrate or flour.
