Spectroscopy of Food Dyes
Summary:
Dyes are added to colorless food; there are nine food dyes certified for food use in the United States. The Food and Drug Administration demands that all food dyes undergo an approval process. In this experiment a spectrometer was used to measure the absorbance spectrum of different food dye solutions. The absorbance spectrum is used to show how strongly or how poorly a compound absorbs the wavelengths of different lights. The absorbance was measured of three different colored substances. Additionally, after determining the absorbance of the different colors, the experiment will use the absorbance to calculate the concentration of dye in beverages. Through Beer’s

    For this lab, zeolite and magnetized zeolite were synthesized and compared with charcoal to find out with would be the most effective in the sequestering of Procion Red dye. Finding the concentration and absorbance of each zeolite, magnetized zeolite, and charcoal, along with a calibration curve, the best adsorbent is determined. Charcoal was the overall best sequestration of the Procion Red dye, since the adsorbent was highest compared to the others. Introduction Pollution has increased in the environment over the years, so the purpose of this experiment is to find the best adsorbent of chemicals to reduce the pollution.

    I. Artificial dyes are found in a majority of processed foods in America. Most of these synthetic dyes are made of or based off of petroleum, a crude oil. Since these dyes are mainly petroleum based they can cause serious health risks on people, especially those diagnosed with ADHD, attention deficit/hyperactive disorder. Because of these potential dangers, laws dating back to the 19th century have been passed, banning the addition of dyes and other harmful substances to foods. Through the years there have been many debates, laws and protests against food dye and their effects on humans and animals.

  • Indigo Dye Research Paper

    918 Words  | 4 Pages

    “In 1775, more than a million pounds of indigo was exported from South Carolina to England” (Indigo’s Political, Economic, Cultural History 1). This massive amount of dye being traded was due to many factors that made it nearly the perfect trade commodity. The process of indigo dye being made by slaves in South Carolina in the 1700s is shown very well in the book Someone Knows My Name by Lawrence Hill. The production of this indigo dye has an extensive history of being extremely arduous to produce naturally, but results in a compact substance that will last a long period of time and be very valuable.

    Introduction The purpose of this lab is to use control variables to help identify different macromolecules. Biological systems are made up of these four major macromolecules: carbohydrates, lipids, proteins and nucleic acids. Carbohydrates are sugar molecules (monosaccharides, disaccharides, and polysaccharides) which make them the most abundant macromolecule on the earth. Lipids (oils and fats, phospholipids and steroids) are insoluble in water and perform many functions such as energy source, essential nutrients, hormones and insulators (Lehman, 1955).

    Jaspreet Singh Professor Paratore Biology 1 November 1, 2014 Spectrophotometry Identifying Solutes and Determining Their Concentration Statement of the Exercise or of the Problem The purpose of the lab experiment was to attain the following objectives: • Learning to Operate the Spectrophotometer • Construct absorption spectra for cobalt chloride and chlorophyll. Hypothesis If greater and higher concentrations of cobalt chloride are added to each solution then greater amounts of light would be absorbed by each solution. Thus a liner relationship will result in which the absorbance of a substance would be proportional to its concentration, which will be depicted, in a linear graph.

    This being that through the concentrations 40% to 10% the absorption of the solute was rather low, although some spikes on the Ethanol, although an increase in the absorption at 40% in Methanol, which could show the beginning of the required concentration for the membrane to break down and let out the pigment. This could be due to that the Ethanol and Methanol was not able to disrupt the lipid bilayer and absorb the beetroots membrane that gives it it’s pigment. This showing that the time or concentration of the Ethanol and Methanol was not long or high enough for the pigment to be absorbed into the solution making the absorbance really low as there was barely any colour change on the solute. The membrane although not reacting with alcohol present and it making the water less polar, it is evident that the membrane is soluble in water and the levels are higher as the membrane was able to be absorbed by the water, increasing the solutes absorption. Propanol on the other hand was able damage the membrane with a concentration of 20% up, which caused at least 3 times the absorption rate.

    CONCLUSION When you put an egg in vinegar, we see that the shell dissolves, but do you ever wonder why? An egg is made mostly out of calcium carbonate which reacts with an ingredient in vinegar, acetic acid. Acetic acid is about 4% of the vinegar and what breaks apart the solid calcium carbonate crystals. The bubbles we see, from the egg, is the carbonate that make carbon dioxide and the other calcium ions float free. This is the equation: CaCO3 (s) + 2 HC2H3O2 (aq)

    Use these results to determine the product concentration, using Beer-Lambert’s Law: A= ɛCl (where A is the absorbance, ɛ is the molar absorptivity, C is the product concentration and l is the length of solution that the light passes through). Calculate the product concentrations at every minute for 10 minutes for all 7 of the test tubes using Beer-Lambert’s Law. Plot a graph of product concentration vs. time and then use the gradients of the 7 test tubes to determine the velocities of the reaction. After calculating the velocities, plot a Michaelis-Menten graph of velocity vs. substrate concentration.

    Conclusion The GC ethanol analysis method described above has a simple concept, its rapid, and extremely accurate, determining ethanol precisely without interference from other beverage components. With this method, it takes only 7 to 8 min to complete a sample analysis for the determination of ethanol content in a beverage sample. Analyst handling is minimized to prevent deviation in results or possible human error. This method requires a gas chromatograph and a digital integrator, both reasonably expensive and sophisticated pieces of equipment.
