Advances, limitations, and considerations on the use of vibrational spectroscopy towards the development of management decision tools in food safety

Trends in authentication of edible oils using vibrational spectroscopic techniques

“…Most of the incident photons undergo elastic (Rayleigh) scattering, where they retain the same energy and frequency as the incident light. 19 However, a small fraction of the incident photons undergo inelastic scattering, known as Raman scattering. In Raman scattering, the incident photon interacts with the sample molecules, causing a change in the energy state of the molecule.…”

“…In Raman scattering, the incident photon interacts with the sample molecules, causing a change in the energy state of the molecule. 19 The energy difference between the incident and scattered photons corresponds to the vibrational or rotational energy levels of the sample molecules. 19 As in MIR spectroscopy, Raman spectroscopy also provides well-resolved spectra, assignable to specific chemical groups; however, spectra are more responsive to molecular structure and symmetry.…”
