WebSince dyes contain the color substance, they absorb light from the visible spectrum. To find what food dye is present, a UV-vis spectrometer is used. UV-vis spectrometer uses white light for the absorption, and white light is the composition of many different wavelengths. WebFluorochromes have unique and characteristic spectra for absorption (excitation) and emission. A single dye is excited at a particular wavelength and emits a photon at a higher wavelength. A tandem dye consists of a donor and acceptor fluorochrome molecule, placed in close proximity, allowing for energy transfer between the two.
