ABSTRACT:
The production and use of a stable ruby red natural colorant prepared from an anthocyanin derived from purple hulled sunflower is described. The production of the ruby red natural colorant comprises the extraction of anthocyanin with an organically acidified aqueous solution and separating the extract from residual material. The extract can be concentrated to produce a ruby red concentrate. The natural colorant produced is stable over a wide pH range and upon exposure to light and elevated temperatures. The natural colorant is useful as a coloring agent for food products, cosmetics, pharmaceuticals and other materials.
