lab was to determine the food dyes present in a selected beverage‚ their concentration‚ and then replicate the solution within a 20% margin of error. The beverage we chose was Gatorade Frost Riptide Rush. A spectrometer was used to determine which food dyes were present in the sampled beverage‚ red 40 and blue 1 were determined to be present. The next step was to determine the concentration of the dyes‚ this was done by testing the absorbance of the red 40 and blue 1 dyes at varying concentrations;

The Chromatography of Food Dyes and determination Of the Dyes Present in M&M Candies Procedure To complete this lab‚ I first mixed the solvent solution consisting of the proper ratio of water‚ salt‚ and isopropyl alcohol in a Pyrex measuring cup. I then prepared my chromatography papers for 2 trials by drawing‚ with a pencil‚ the appropriate lines and labels. Using a toothpick‚ I added the color to the paper‚ and then repeated until the color was strong. I repeated this step several more

Methods: In this lab using the bag of FD&C dyes‚ bag of M&M’s‚ 2 packs of Kool-Aid ‚ and a pack of Clover Valley store brand food coloring I am going to place a drop of each dye at the bottom of the chromatography paper. For the experiment with the rubbing alcohol I also placed a drop of each dye‚ but used a paper coffee filter. In order to get the dye color extracted from the M&M’s and Kool-Aid I added a little additional water. After applying all of the dyes and allowing them to dry completely I placed

experiments carriedout for the degradation of fabric dyes from aqueous solution using Chara and Chara beads are discussed below.Various analytical techniques like UV-Vis‚ FTIR spectroscopy were used to confirm the decolorization as UV-Vis spectroscopy; FT-IR spectroscopy and toxicity bioassay were truly used [14]. Also‚ Fourier transform infrared spectroscopy (FT-IR) is widely used to confirm the product obtained after decolorization of dye degradation experiments [15]. It helps in determination

Matt Cramer Alex Chen 2/7/17 Food Dye lab Spectroscopy of Food Dye Lab Introduction You’re coming off the field after a hard fought game against your rival team. You are needing a drink and you grab a blue Powerade off the managers table. The drink delivers the electrolytes needed to sustain throughout the rest of the day. Then‚ the athlete starts to think how much of his blue Powerade is actually made from the blue food dye. The food dyes have had a tremendous affect on global economics

Chromatography of Food Dye Chem 180-DL3 Abstract: The goal of this experiment was to use different dyes to determine the Rf value. Chromatography is done to determine the presence of a mixture in a substance. In this experiment different dyes were used such as McCormick food coloring‚ M&M’s‚ Kool-Aid‚ and the dyes that came with the lab kit. Experiment and Observation: In this experiment a 50mL beaker was filled with luke warm water and a pinch of salt water was dissolved in it
