Abstract: Oilseed, particularly whole canola seed, is separated under non-oxidizing conditions, in a non-aqueous solvent system, into high quality oil and proteinaceous flour food components, and a seed coat meal (hull) byproduct. Maceration in a solvent, sequential liquid cyclone separations, and recovery of components and solvent all take place in completely enclosed liquid flow-through systems with solvent recycle, in a relatively short time. This rapid processing avoids oilseed exposure to elevated temperatures and substantially prevents breakdown of certain of its chemical components into antinutritional compounds. Flaking, cooking and pressing stages are not required.
