A stabilized crocetin-containing colorant which has as an effective component a crocetin included by cyclodextrin. This colorant is imparted with resistance against light and various chemicals to crocetin, which is a hydrolysate of crocin, the main component of the carotenoid gardenia yellow pigment. The colorant may be added to various food products for use of crocetin as a stable coloring matter.

DETAILED DESCRIPTION An object of the present invention is to impart to crocetin resistance against light and chemicals for its stability, thus providing a method for its use as a colorant.
