The food dyes contain propylene glycol in addition to the dyes and water. The candy shells contain sucrose, corn syrup, corn starch and gum acacia. Do you think this affects the movement of the dyes on the chromatography paper?

do an experiment: Add more corn syrup to the dyes, and see if there is a change. YOu can do the same with the rest of the chems.
