Abstract:
This research was proposed to study the effects of direct Sunlight exposure on selected artificial food dyes(Sunset yellowE110, TartrazineE102, Allura RedE129, Fast GreenE142). These dyes were desolved in distilled water and studied using Ultra-Violet Spectrometer (Uv-Vis)before and after sunlight exposure. The obtained spectra for these dyes showed increase in the absorbance and hence concentration which indicates increase of the side effects of the dyes on people.
Chemical structure of these dyes were figured out using Fourier transforms infrared spectroscopy (FTIR). This showed existence of Alcohols and Phenol(chemical benzene). It was concluded that exposure of food mixed with artificial dyes to sunlight may cause negative impact on human.
