EVOODec is a tool for calculating the concentration of the pigments usually cointened in the extra-virgin olive oil from a spectral deconvolution of the near-UV / Visible absorption data. The program allows to choose the spectral range and to select specific pigments to perform the deconvolution. Automatical and manual deconvolution modes are availble. Results are shown both in a graphical and in a text form.
A pre-loaded data set containing seven pigments is available for deconvolution. The contribuition of the oil matrix is accounted by also including the triolein (TRIO) absorption. The pigments actually available are:
- Pheophytin a (Pheo-a)
- Pheophytin b (Pheo-b)
- Beta-Carotene (b-CAR)
- Lutein (LUT)
- Neoxanthin (NEX)
- Chlorophyll a (Chl-a)
- Chlorophyll b (Chl-b)
