METHOD FOR PREPARTING A DEODORIZED COLORANT OF BRASSICACEAE PLANT

摘要

A colorant of a plant belonging to the family Brassicaceae which has no or significantly reduced smell originating in the Brassicaceae plant, a colorant formulation containing this colorant, and a process for producing the odorless or almost odorless colorant of the Brassicaceae plant. This colorant can be prepared by treating an adsorption-treated Brassicaceae plant colorant extract by at least one method selected from among adsorption, ion exchange, acid treatment, and membrane separation to thereby give an aroma component concentration of 100 ppm or less in case where the color value E<10%>1cm is 80.
