Abstract

A process for the recovery of lecithin from mucilaginous substances obtained in the production of vegetable fats and oils by extraction with a solvent which is gaseous under normal conditions. The mucilaginous substances are extracted at a pressure from 2.times.p.sub.k to 500 bar and at a temperature from 0.degree. C. to <T.sub.k for a period from 15 to 60 minutes to form a charged compressed solvent phase containing extracted substances and an extraction residue containing insoluble lecithin. Then, the charged, compressed solvent phase is separated from the insoluble lecithin. Thereafter the extracted substances are separated from the charged, compressed solvent phase and the gaseous solvent is returned to the extraction stage. The lecithin is removed from the extraction stage and is obtained in solid form by evaporating the solvent.
