Abstract
The invention relates to a process for the recovery of the lupine alkaloid lupanin and, if necessary, other lupine alkaloids such as 13-hydroxil lupanin from the aqueous alkaloid extract obtained by processing or debittering lupine seeds, having the following process steps: a) The aqueous alkaloid extract is adjusted to a pH of 10.0 to 12.0, b) A liquid/liquid extraction is performed using an ether, and c) the organic phase of the aqueous phase is separated and the lupanin is recovered from the organic phase, and, if necessary, d) the aqueous phase from process step c) is adjusted to a pH of greater than or equal 12.5 and this is followed by a liquid/liquid extraction using a chlorinated hydrocarbon, and the further lupine alkaloids, in particular 13-hydroxil lupanin, are recovered from the organic phase.
