Process for carefully preparing plant extracts

Abstract

A process is described for the gentle production of plant extracts, and in particular high-quality coffee extract by multi-stage cold extraction of ground roasted coffee. By stepwise milling the solid ingredients in aqueous slurry to colloidal fineness in the second and third extraction stages, a high overall yield can be achieved at low temperatures. The residue may optionally be subjected to a high temperature short term treatment.
