    摘要: The purpose of the present invention is to provide: a gardenia blue pigment which contains a product of a reaction between genipin and a compound having a primary amino group, and which offers a bright, fresh blue color tone having reduced redness; and a method for producing same. This gardenia blue pigment, which offers a bright, fresh blue color tone having reduced redness, is obtained by carrying out a first step in which genipin and at least one peptide selected from the group consisting of soybean peptides, sesame peptides, and rice peptides are reacted in a solvent without supplying an oxygen-containing gas, and a second step in which a reaction liquid obtained in the first step is processed under an oxygen-containing gas supply.
