Disclosed herein are pigment compositions for meat substitutes and meat substitutes including such pigment compositions. The pigment compositions include a thermolabile EforRed variant polypeptide. The pigment compositions provide a pink and/or red color to a meat substitute composition that transitions to a brown color after cooking. For example, the thermolabile EforRed variant may have a sequence at least 80% identical to SEQ ID NO:1 and include (i) an XYG chromophore tripeptide and (ii) a mutation at a position selected from the group consisting of phenylalanine (F) 68, threonine (T) 102, aspartate (D) 119, D130, alanine (A) 139, F163, F206, A214, and combinations thereof relative to SEQ ID NO:1. 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 EforRed termolábil. 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. Por ejemplo, la variante EforRed termolábil puede tener una secuencia al menos 80 % idéntica a la SEC ID NO:1 e incluir (i) un tripéptido cromóforo XYG y (ii) una mutación en una posición seleccionada del grupo que consiste en fenilalanina (F) 68, treonina (T) 102, aspartato (D) 119, D130, alanina (A) 139, F163, F206, A214 y combinaciones de estas en relación con la SEC ID NO:1.
