Food dyes are commonly used in a variety of beverages, including soft drinks, energy drinks, and sports drinks, to enhance the visual appeal of the product. However, the use of food dyes in beverages has been a controversial topic due to concerns about their safety and potential negative health effects. In this essay, we will examine the use of food dyes in beverages through a lab analysis and discuss the potential consequences of consuming these dyes.

To begin with, it is important to understand the different types of food dyes that are commonly used in beverages. These dyes are typically derived from synthetic sources, such as petroleum, and are classified as either "certifiable" or "exempt" dyes. Certifiable dyes, also known as "coal tar" dyes, are subject to strict regulations and must be approved by the Food and Drug Administration (FDA) before they can be used in food and beverages. Exempt dyes, on the other hand, are not subject to the same level of regulatory oversight and can be used without prior approval.

To analyze the presence of food dyes in beverages, a lab would typically use a technique called chromatography. This technique involves separating the different components of a sample, such as the dyes in a beverage, based on their physical and chemical properties. The separated components are then detected and quantified using a spectrophotometer or other analytical instrument.

Through this analysis, it is possible to determine the concentration of various food dyes in a beverage and assess whether they are within the acceptable levels set by the FDA. It is important to note that the FDA has established maximum levels of certifiable dyes that are considered safe for consumption, but there are no specific limits for exempt dyes.

There have been a number of studies that have examined the potential health effects of consuming food dyes in beverages. Some research has suggested that certain dyes, particularly those that are derived from petroleum, may be linked to cancer and other negative health outcomes. Additionally, there is evidence to suggest that the consumption of certain food dyes may contribute to hyperactivity and other behavioral issues in children.

Despite these concerns, the use of food dyes in beverages remains a common practice in the food industry. Many companies argue that the levels of dyes used in their products are within safe limits and do not pose a significant risk to consumers. However, it is important for consumers to be aware of the potential risks associated with consuming food dyes and to make informed decisions about the products they choose to consume.

In conclusion, the use of food dyes in beverages is a controversial topic due to concerns about their safety and potential negative health effects. Through a lab analysis, it is possible to determine the concentration of various food dyes in a beverage and assess whether they are within acceptable levels. While some research has suggested that certain dyes may be linked to negative health outcomes, the food industry continues to use these dyes in their products. It is important for consumers to be aware of the potential risks associated with consuming food dyes and to make informed decisions about the products they choose to consume.

Graph 2: Spectrum Graph for Monster Hydro Purple Passion Exporting the data from LoggerPro and creating our own spectrum, two maximum peaks are clearly visible in the graph for the beverage. Using the spectrophotometer, dierent concentrations of blue 1 dye was tested for the wavelength and absorbance values. Turn on spectrophotometer and connect it to laptop, warm up for 15 minute. The desired wavelength is then focused onto the sample cell to detect any absorption or emission of light by a substance in the sample. Consult the ingredients label for a blue-colored sports drink or ther consumer beverage. Then, each color would be measured for its temperature without light being emitted into the solutions and with light being emitted into the solution.

Step 1 Action: We dissolve a few grains of the solid drink in about a mL of water. The spectrophotometer measures absorbance by measuring the amount of photons that pass through the sample. The sum of Red 40 V2 and Blue 1 V2 was then subtracted from V2 in order to determine how much deionized water was needed in order to properly dilute the dye. However, the anionic forms are generally not used due to the abundance of free silanols generated from alkaline mobile phases, which leads to poor analyte retention, peak tailing, and low efficiency. This is a quantitative analysis of the dyes.
