Summary
This 2023 review examines the state of near-infrared spectroscopy as a non-destructive, rapid analytical technique for quantifying bioactive compounds in foods—including phytochemicals, micronutrients, and other health-relevant constituents. The authors synthesise current applications and methodological frameworks whilst acknowledging persistent challenges in accuracy, standardisation, and model transferability across diverse food matrices. The paper signals future research directions as the field moves towards integrated spectroscopic platforms and machine-learning approaches.
UK applicability
NIR spectroscopy applications reviewed here are relevant to UK food quality assurance, crop breeding programmes, and supply-chain verification of nutrient claims. Adoption of standardised NIR protocols could support nutrient profiling requirements under UK food labelling and health claim regulations.
Key measures
NIR spectroscopy methodology for bioactive compound detection; calibration models; spectral analysis techniques; performance metrics of NIR-based quantification
Outcomes reported
This paper reviews current applications, limitations, and emerging approaches in using near-infrared (NIR) spectroscopy to quantify bioactive compounds in food products.
