Spectroscopy White Papers
Olive Oil Quality Assessment with UV-Vis Spectrophotometry
UV-Vis spectrophotometry is a simple and efficient technique for the analysis and evaluation of the quality of olive oil. Extra virgin, virgin, and lower-quality olive oils can be distinguished by measuring their absorbance at four UV wavelengths. The full UV-Vis absorption spectrum provides valuable qualitative and quantitative information when oil adulteration is suspected.
