Raman Spectra of oil mixtures (GRAPPE, Ecole Supérieure des Agricultures, INRAE, 55 rue Rabelais, 49000 Angers, France)
Sampling: The document present a series of 605 Raman Spectra of different mixtures of Extra Virgin Olive Oil (EVOO) and Sunflower oil.
Samples are mixture of Extra Virgin Olive Oil (EVOO) and Sunflower oil and are classify from 0 to 100% EVOO

Set up
Raman spectrometer QEPro (Ocean Insight, USA)  set up for 785 nm with a  Raman Shift: from 500 cm-1 to 2500 cm-1, a typical optical resolution of 11 cm-1 full width at half maximum (FWHM) and an integration time of 1000 ms. For all resulting spectra 10 scans were done for each acquisition.  
A Solid-state laser diode (Ocean Insight, USA) with an excitation wavelength of 785 nm was used with a power of 400 mW and a spectral FWHM inferior to 0.15 nm. 
A a general-Purpose Fiber Optic Raman Probes (Ocean Insight, USA) was used with a specific quartz cuvette holder with a working distance of 0.5mm. 
In accordance with our Design of Experiment 5 spectra were recorded with each mixture.

Dataset organisation
We  present 605 Raman spectra for each line and they are organized with the following structure.
Column A	Acquisition date
Column B	Observation number for a same date
Column C 	Spectrum number for the same mixture
Column D	Percentage of EVOO
Column E	Percentage of Sunflower oil
Column F	Acquisition time in ms
Column G	Number of scans
Column H	Laser Power in mW
Column I	Data set origin CALIBRATION, VALISATION or PREDICTION
Column J to AAQ	Raman intensities for different Raman Shift in wavenumbers from 500 to 2500 cm-1
