Food grade colored fluids which include food grade dyes and food grade glycols are provided. Also provided are methods for applying the food grade colored fluids directed to the surface of an edible substrate, and edible substrates having the food grade colored fluids applied to a surface thereof. The food grade colored fluids may optionally include glycerine and water. In one embodiment, the food grade glycol makes up at least about 25 wt.% of the colored fluid and water makes up no more than about 35 wt.% of the colored fluid. On présente des fluides colorés de qualité alimentaire comprenant des colorants de qualité alimentaire et des glycols de qualité alimentaire. On présente également des méthodes permettant d'appliquer les fluides colorés de qualité alimentaire sur la surface d'un substrat comestible, ainsi que des substrats comestibles à la surface desquels les fluides colorés de qualité alimentaire ont été appliqués. Les fluides colorés de qualité alimentaire peuvent de manière facultative, renfermer de la glycérine et de l'eau. Dans un mode de réalisation de l'invention, le glycol de qualité alimentaire constitue au moins environ 25 % en poids du fluide coloré, et l'eau constitue au plus environ 35 % en poids du fluide coloré.
