Characteristics of yellow color produced by Monascus sp. Y7, mutant of Monascus anka Nakazawa et Sato IFO 4478, was studied. The extracted color was stable in wide range of pH, heat, and UV light, whereas relatively unstable in sunlight. The stability of yellow color was not changed by adding the various metal ions of 10^(-3)M concentration, however, it was somewhat unstable by adding the Ca^(++) and Cu^(++). Yellow degree(b/a of Hunter's color value) of mutant color was similar to those of other natural yellow colorants such as annatto, gardenia yellow and carthamus yellow. Thus it may be concluded that yellow color of mutant Y7 is useful food additives as the alternative natural colorant.
