Summary:A colorant of a plant belonging to the family Brassicaceae which has no or significantly reduced smell originating in the Brassicaceae plant; a colorant preparation containing this colorant; and a process for producing the odorless or almost odorless colorant of the Brassicaceae plant as described above. This colorant can be prepared by treating an adsorbed extract containing the colorant of the Brassicaceae plant by at least one method selected from among adsorption, ion exchange resin-treatment, acid-treatment and membrane separation to thereby give a smell component concentration of 100 ppm or less in case where the color value E<10%>1cm is 80. L'invention concerne un colorant d'une plante appartenant à la famille des Brassicaceae ne présentant aucune odeur ou une odeur réduite de manière significative provenant de la plante Brassicaceae, une préparation de colorant contenant ce colorant, ainsi qu'un procédé de production du colorant inodore ou presque inodore de la plante Brassicaceae. Ce colorant peut être préparé par le traitement d'un extrait adsorbé contenant le colorant de la plante Brassicaceae à l'aide d'au moins un procédé choisi parmi l'adsorption, le traitement par résine échangeuse d'ions, un traitement à l'acide et une séparation sur membrane, afin de donner ainsi une concentration de constituant d'odeur de 100 ppm ou moins dans le cas où la valeur de couleur E<10 %>1cm est de 80.
