Recommended: Chromatography term paper

After extracting, filtering, and condensing the blue and pink dyes off of the candies, it can be determined that the Blue candy is FD & C Dye Blue 1 and the Pink candy is a mix of Yellow 5 and Red 40. During the solvent evaporation for the blue dye, it was observed that when concentrated, the transparency of the dye was similar to that of Blue 1. During the paper chromatography of Project 2 Session 1, the blue dye showed on the chromatogram to have the highest spot height. Similar to the paper chromatography today which the blue dye was observed having the higher spot height as well. Figure 3 of the Project 2 In-Lab Report displays Blue 1 of having an Rf value of .729. The blue dye off of the candy, as seen in Figure 2, has an Rf value of .657.

  • Green Frosting Lab Report

    616 Words  | 2 Pages

    The essential points of the green-frosting are the concentration and absorbance value in each diluted which the process of serial dilution. The standard curve of Blue#1 and yellow #5 provide the equation of the trend-line in order to calculate the concentration in the diluted solution of the green frosting. The mole of dye in 100mL green stock solution, mole of dye in 5 gram and 1 gram of frosting, the Beer –Lambert Law, and the compare to amount desired by the company can be determined. The Beer-Lambert Law is the relationship between color and the concentration and equation A=Ebc. The “A” is absorbance, the “C” is a concentration in molarity, the “E” is a molar absorptivity and “b” is the path-length. The goal of the lab is to use the absorbance and the Beer-Lambert law to determine the amounts of blue#1 and yellow #5 in the green frosting.

    The lab experiment did prove that Crayola colors are not of pure substances but rather a mixture of specific color compounds needed to produce said colors. The experiment also proved that different color pigments have different densities (the lighter ones moved up the filter paper with the water, while the heavier ones adhered to the filter paper longer.)

    These synthetic dyes are preferred more than any other dye by companies for the intensity of brightness of color and the uniformity it gives the food unlike some natural dyes would give. These dyes are derived from other food like grapes, potent fruit, spices like saffron, paprika and vegetables like carrots, beets and algae. Of course the natual dyes can also cause a discussion if they are safe or not. In 1998 some natural food dyes were made out of female beetles to replace unnatural red dye. (stevens, Beil)

  • Dyes in Foods: Natural versus Synthetic

    878 Words  | 2 Pages

    According to the The Columbia Electronic Encyclopedia, a dye is a “synthetic or natural coloring used to color various materials.” Today, many dyes are used in foods all around the world. As of January 2014, the United States Food and Drug Administration certifies nine different dyes-Blue 1, 2; Green 3; Red 3, 5, 6, 40; Yellow 5 and 6 (Beil). Blue dyes are usually found in ice creams, blueberry-flavored foods, and baked goods. Red dyes are often in candies, cookies, and chips. Cheeses and buttered treats contain yellow dyes while green dyes are not as common in food products but are in fruit-flavored candies. Natural colored foods could be strawberries or ketchup. Even though artificial colorings are allowed, the amount used in foods is limited. European countries have conducted research and banned all dyes from being added to their foods. These countries believe dyes pose as a health threat. Some citizens from the United States have said dyes are not necessary in foods and others wish that dyes will still be used in their favorite foods. However you look at it, dyes being used in foods is a very controversial health problem today.

    It changes from blue to red with acids but loses its colour in the presence of certain chemicals, one of which is vitamin C. DCPIP solution can be used to test for the presence of vitamin C in foods. Hypothesis Orange juice has the highest content of vitamin C. Citrus fruits have a higher content of vitamin C. The orange and lemon juice contain more vitamin C than the pineapple juice. Furthermore, as lemons are more acidic than oranges, I predict that the orange juice will contain more vitamin C than the lemon juice. Vitamin C affects, the ph the more vitamin C the higher the ph.

One solution that should have changed color was solution 4, the base-hydrolyzed aspartame, but it did not produce a color change when aqueous ceric ammonium nitrate reagent. Water and fresh aqueous aspartame are not going to produce a color change because there is no alcohol group in there structure.
