Figure 4

FT-IR spectra, normalised for the wavelength of 1745/cm, recorded for the respective grape seed oil samples: Dornfelder 2015 (dashed green), Hibernal 2017 (solid green), Neuburger 2017 (dashed gray), Pálava 2015 (solid gray), Pinot Gris 2015 (dashed blue), Riesling 2015 (solid blue), Sauvignon 2017 (dashed red), Tramin 2015 (solid red), Zweigeltrebe 2015 (dashed black) and Zweigeltrebe 2017 (solid black) respectively. All spectra are presented in the spectral range of 700–3600/cm and recorded at 23 °C.
