PROBLEM TO BE SOLVED: To provide a pigment formulation with which a product colored in bright red originating from a carotenoid pigment can be produced while inhibiting discoloration even when the pigment formulation has been added to a fat-containing product raw material and has been heat-treated, for which a step to strongly agitate the product raw material such as high-speed agitation is not necessary, and which has a high level of freedom for selecting a stage of addition to the product raw material.SOLUTION: A pigment formulation contains a carotenoid pigment, a discoloration inhibitor, and a dispersion aid (other than the discoloration inhibitor), in which the discoloration inhibitor is an organic polymer having solubility of 1 g or less based on 1 L of water at 20°C and solubility of 1 g or more based on 80 vol.% of ethanol aqueous solution at 20°C, and the dispersion aid is at least one of polysaccharide and protein.SELECTED DRAWING: NoneCOPYRIGHT: (C)2018,JPO&INPIT【課題】油脂を含む製品原料に添加して加熱処理した場合であっても、変色を抑制しつつ、カロチノイド色素に由来する鮮明な赤色に着色した製品を製造することが可能であるとともに、高速撹拌等のような製品原料を強く撹拌する工程を必要とせず、かつ、製品原料に添加する段階を選択する自由度の高い色素製剤を提供する。【解決手段】カロチノイド色素、変色抑制剤、及び分散補助剤(但し、変色抑制剤を除く)を含有し、変色抑制剤が、20℃の水1Lに対する溶解度が1g以下であり、かつ、20℃の80体積%エタノール水溶液に対する溶解度が1g以上の有機高分子であり、分散補助剤が、多糖類及びタンパク質の少なくともいずれかである色素製剤。【選択図】なし
