Abstract
A process is disclosed for isolating and concentrating a natural colorant of bland taste found in plants containing betanin. The process involves adjusting the pH of an aqueous extract of the betanin-containing plant to the isoelectric point of betanin, contacting the pH-adjusted extract with a non-ionic adsorbent to concentrate the betanin pigment on the adsorbent, eluting the adsorbent to remove the betanin pigment, and separating the pigment from the eluting agent.
