Abstract

The invention relates to a method for separating off coloring components from aqueous plant extracts in which magnesium ions (Mg<2+>) are added to the plant extract, at least one alkaline component is added to the plant extract, a precipitate is formed, and the precipitate formed is separated off from the plant extract.
