Literature review demonstrates the efficacy of mid-infrared spectroscopy combined with chemometrics for detecting food adulteration, highlighting its promise for rapid and routine quality control.

Key Points

To review the principles, chemometric methods, and recent applications of mid-infrared spectroscopy for evaluating authenticity and detecting adulteration in major food commodities.
Surveyed peer-reviewed literature published from 2010 to mid-2020 on mid-infrared (MIR) spectroscopy in food quality and authenticity analysis.
Evaluated sampling methodologies, with an emphasis on attenuated total reflection (ATR) acquisition mode.
Examined chemometric data-processing approaches across five food categories: coffee, dairy products, honey, olive oil, and wine.
MIR spectroscopy coupled with chemometrics reliably differentiates authentic foods from adulterated samples by mapping unique chemical fingerprint profiles.
The combination of ATR sampling and multivariate statistical models demonstrates consistent qualitative and quantitative detection of misrepresentation across all reviewed matrices.
The approach provides a rapid, non-destructive, user-friendly, and reagent-free alternative suitable for routine monitoring and official regulatory food control.
