Date Feb. 17, 1983.In a process for debittering bitter lupin seed the lupin seed is firstly very finely milled, more specially in a ball mill, and it is then extracted while cold and in counter current with solutions of lupin seed extract with different concentrations in steps, the solvent used being water. The filter cake produced on extraction is dried. After being increased in concentration, the solutions of lupin seed extract are stored and possibly further concentrated. The apparatus for use in the process has in addition to the ball mill a flat bed extractor and a number of storage spaces placed in circuit with each other and with the extractor, such spaces being used to take up the solutions of lupin seed extract. The debittered lupin seed is a high-quality nutrient for man and animals whose protein and fat levels are almost equal to the levels in the lupin seed before debittering, while the concentrate of the lupin extracts containing the bitter substances have a strong plant growth promoting effect, and may be used against many plant pests and for pharmacological purposes.
