Determining Food Dye Content Lab was to identify the food dye coloring in green apple Gatorade, and determine the dye’s concentration to ultimately recreate a solution containing the same concentration of dyes as the original. To determine the concentration of the dyes present in the green apple Gatorade, a spectrometer was used to measure the wavelengths and absorbance values for the given dyes. A sample of the green apple Gatorade was tested in the spectrometer to measure its absorption and compare the values collected to stock dyes provided in lab. The data displayed that the green apple Gatorade contained blue-1 food dye because the Gatorade’s wavelength at peak one was 422.3 Nm, and blue-1 food dye’s peak one was 423.7+-.1.5…

How Food Dyes Can Affect Your Health Have you ever wondered how the ingredients like artificial color and dyes in your food could affect your health? There are thing in our diet that can cause us health problems. Food dyes are linked to health problems in many people. You may be asking yourself what are food dyes. Food dyes are a mix of chemicals to add color to food. Food dyes are linked to ADHD. For more than thirty years scientists have studied how food dyes is linked to ADHD (“Food Dye”).…

concentration of Blue Dye 1 in Cool Blue Gatorade. In today's society most people are health conscious and food coloring and dyes have been a controversial topic. Blue Dye 1 is one of the most popular FDA-approved dyes used in food such as fruits, sauces, and baking mixes. Such dyes are not limited to foods but also used in shampoos, detergents, and vitamins just to name a few (Hennessey). There have been many studies pointing to the fact that dyes are toxic, carcinogens and contributors to…

Synthetic Dye Assignment Dye: Sunset Yellow FCF Caitlin Walker Sunset Yellow FCF, more commonly known as Yellow 6, is an orange azo dye3. This dye is petroleum-derived and its absorption is dependent on the pH. Minimum absorption occurs at 480 nm with a pH of 1 and maximum absorption occurs at 443 nm with a pH of 13. Sunset Yellow FCF is soluble in cold water2. Sunset Yellow FCF has the following structure (Figure 1). Sunset Yellow FCF is commonly used in food, cosmetics, and drugs. It is…

Introduction Color variation is something we take for granted, especially when it comes to clothing. The colors from most of our clothes are obtained from fruits and vegetables, such as cranberries, strawberries, blackberries, some may come from flowers. Which can be traced back to an earlier time, when natural dyes were used for coloration of clothes and even linen that was used to wrap mummies! There are many natural dyes and each one has a different reaction with different fabrics. So, in…

When you go to the store and buy dyes, such as food coloring dye, they are useless if you want to tie dye your shirt. All they would do is stain your clothes and easily wash out. If you want a dye that chemically combines to your shirt so it doesn’t come out, I would suggest getting a fiber reactive dye. Fiber reactive dyes form covalent bonds between the dye you use and the fiber. The dye permanently attaches to the cellulose fibers using a covalent bond. Covalent bonds are the strongest…

INTRODUCTION Dyes exist in natural and synthetic forms in the world; they are used for the purpose of changing colors of different materials. William Perkins first discovered the azo dye on accident after adding alcohol to a product in the lab. They have the ability to do this due to the molecules of the dyes possessing conjugation. Conjugation is defined as p-orbitals overlapping which causes the electrons within to be delocalized; it is also seen in molecules and compounds that contain…

Tartrazine Tartrazine is a chemical that contains numerous positive and negative effects. It is a lemon yellow azo dye mainly used as a food coloring. It has no taste, but s commonly used in foods we eat. Tartrazine’s chemical symbol is C16H9N4Na3a2. The molar mass of Tartrazine is 534.3g/mol. Also, Tartrazine’s melting point is 300 c. It is often used in bakeries on frosting and other pastries to add a splash of color into it. It is extensively used for a variety of different products. But, if…

Introduction According to Bio-Rad, Alamar Blue is a “cell viability assay reagent which contains the cell permeable, non-toxic and weakly fluorescent blue indicator dye called resazurin.” (Bio-Rad, n.d.). Meaning that the resazurin is going to be using an oxidation-reduction (REDOX) indicator that will undergo a color change due to the response of the cellular metabolic reduction. “The reduced form resorufin is pink and highly fluorescent, and the intensity of fluorescence produced is…

If you got some dye on your carpet while you where coloring your hair, do not fret. If you act quickly, you can get the stain out of your carpet and save your carpet from forever being the same color as your hair. Blot Up The Hair Dye The first thing you need to do is grab a clean washcloth and blot the dye. When you blot the dye, you take the washcloth and gently dap the area, without pressing down too hard. The purpose of doing this is to absorb as much of the hair dye as you can before it…
