Process for alleviating the bitterness of the seed kernels of bitter lupins

摘要

The invention relates to a method for debittering the seeds of bitter lupines, wherein concentration by 5 to 15 ° C stepwise by run under partial exclusion of air and with the use of SO₂, ring extraction phase oriented separation process according to the countercurrent principle with aq previously enriched extract solutions decreasing Kon a bitter stoffhaltiger lupine extract and a debittered protein and fat mass are obtained from the previously ground seed grains. The lupine extract after the extraction at a below 35 ° C to 40 ° C lying temperature under the action of air fermented advantage, its pH rises to 0.2 to 0.5. The profit and growth-enhancing effects of lupine extract to plants is considerably increased and protein losses are greatly reduced.
