Process and apparatus for freeing bitter lupin seed of bitter substances therein

摘要

A process for treating bitter lupin seeds, wherein the seed is reduced to a very fine particle size either before or during a countercurrent extraction using aqueous solutions which contain differing concentrations of lupin-seed extract, produces a material containing bitter substances extracted from the lupin seed which can be used as a biologically active agent, for example, to affect the growth of plants.
