摘要
A process for the treatment of an acid hydrolysate of vegetable matter for separating it into a dark colored fraction and a light colored fraction is disclosed. In a turbulent flow, it is placed in contact with at least one semi-permeable membrane which is stable in an acidic medium under a pressure of from 4 to 50 kg/cm2 which produces a first lightly colored liquid or permeate which passes through the membrane, the average color intensity of which, measured by its extinction, is about one tenth of that of the hydrolysate, and a second strongly colored liquid or retentate which does not pass through the membrane. The dried retentate is used as a seasoning and/or coloring agent.
