Datasheet Color Red Yellow Green Blue Unknown #1 Unknown #2 15 d Re FD&C Name Each food color is made up of two FD&C dyes. The dyes included in the food coloring may include erythrosine (FD&C Red #3) , Allura Red AC (FD&C Red # 40), tartrazine (FD&C Yellow #5), and/or Brilliant Blue FCF (FD&C Blue #1). They comprise the food colorings as follows: Color Red Yellow Green Blue Dye #1 FD&C Red #3 FD&C Yellow #5 FD&C Yellow #5 FD&C Blue #1 Datasheet Dye #2 FD&C Red #40 FD&C Red #40 FD&C Blue #1 FD&C Red #40 Using this chart and your measured Rf values, identify each spot in the food colors. For your unknowns, note the R value(s) and band colors for each solvent. From this information, identify the composition of the unknowns. Take a picture of your completed chromatograms and submit it with your datasheet and post-lab worksheet.
