Obtaining the blue, green and red colorants in peanut chocolate candies using UV-Vis absorption and reflectance spectroscopy

In this application note, we combine a high-power deuterium tungsten-halogen light source (LS-DWHP) with a FLEX spectrometer in a UV-Vis-NIR absorbance and reflectance configuration (this requires the use of a reflectance probe) to obtain the absorbance and reflectance spectra of the blue, green, and red dyes present in peanut chocolate candies.
