Terahertz time-domain spectroscopy combined with chemometrics for detecting homogeneous adulteration in olive oil: A case study of expired and refined olive oils.

Extra virgin olive oil (EVOO) is widely recognized as a premium grade oil, commanding a high market value and a strong reputation for health benefits. The adulteration of EVOO with low grade oils increases, especially when the adulterants are chemically similar. This study developed a detection strategy based on terahe...

Microfluidics-Integrated Spectroscopic Technologies for Food Safety and Quality Assessment: From Complex-Matrix Processing to On-Site Decision-Making

Food safety and quality analysis is shifting from laboratory-based end-point testing toward faster, lower-volume and matrix-adapted on-site decision-making. Near-infrared (NIR), visible-near-infrared (Vis-NIR), hyperspectral, Raman, surface-enhanced Raman scattering (SERS), fluorescence, colorimetric and terahertz appr...
