In order to remove the toxic quinolizidine alkaloids and other nonprotein constituents, hexane‐defatted flakes of lupin ( Lupinus mutabilis ) were extracted under various conditions with ethanol, methanol or their aqueous solutions. Lupin protein concentrates containing more than 70% protein and 0.1–0.2% alkaloids were obtained in high yields by consecutive extractions, countercurrent extraction or semicountercurrent extraction of the defatted lupin flakes with either 80% ethanol or 80% methanol.
