METHOD FOR TREATING AND PROCESSING LUPINE SEEDS CONTAINING ALKALOID, OIL AND PROTEIN

摘要

The invention relates to a method for treating and processing lupine seeds containing alkaloid, oil and protein in order to extract products from the lupine seeds using targeted fractionation, whereby the comminuted lupine seed is deoiled by introducing a solvent and, by adding acid, the residue is removed from substances, preferably alkaloids, which are soluble in the acid. The invention is characterized in that the lupine seeds are comminuted into small discoid flakes and/or shaped in such a way that the comminution of the plant seeds is carried out after the seed which is decorticated or not decorticated and which contains the plant seeds has been subjected to a precrushing using a cooled flocculating roller. In addition, the lupine seeds are heated by the indirect input of heat which ensues, to a large extent, without the use of water. After deoiling, the removal of substances, preferably alkaloids, which are soluble in the acid is effected by an aqueous extraction, whereby an alkaloid-reduced raffinate and an aqueous extract are obtained.
