ABSTRACT:
The production and use of a high-intensity red natural colorant prepared from an anthocyanin derived from the cell line of Daucus carota (carrot) is described. The production of the high-intensity red natural colorant comprises the cultivation of Daucus carota in a cell tissue culture. Carrot cells are extracted from the cell tissue culture after subculturing and a suitable growth period. The extract is then purified in order to isolate the anthocyanin found in the carrot cells. The anthocyanin is then concentrated to produce the red natural colorant of the invention. The natural colorant produced is stable over a wide pH range under various conditions. The natural colorant is useful as a coloring agent for food products, cosmetics, and pharmaceuticals.
