Disclosed herein are pigment compositions for meat substitutes and meat substitutes including such pigment compositions. The pigment compositions include a thermolabile AlacDFX variant polypeptide, e.g. a thermolabile DFX polypeptide including a sequence at least 80% identical to SEQ ID NO:1 and including a mutation at a position selected from the group consisting of I76, H68, E106, K58, E108, K90, I15, I16, I89, Q88, F102, Y80, Y7, and combinations thereof relative to SEQ ID NO:1. The pigment compositions provide a pink and/or red color to a meat substitute composition that transitions to a brown color after cooking. En la presente descripción se describen composiciones de pigmento para sustitutos de carne y sustitutos de carne que incluyen tales composiciones de pigmento. Las composiciones de pigmento incluyen un polipéptido variante de AlacDFX termolábil, por ejemplo, un polipéptido de DFX termolábil que incluye una secuencia al menos 80 % idéntica a la SEC ID NO: 1 y que incluye una mutación en una posición seleccionada del grupo que consiste en I76, H68, E106, K58, E108, K90, I15, I16, I89, Q88, F102, Y80, Y7, y combinaciones de estas en relación con la SEC ID NO: 1. Las composiciones de pigmento proporcionan un color rosa y/o rojo a una composición de sustituto de carne que cambia a un color marrón después de la cocción.
