Fish identification and authentication
8 Oct 2025Species mislabeling and substitution in seafood pose serious risks to food authenticity, consumer trust, and regulatory compliance. Traditional identification methods are slow, expensive, and require lab infrastructure, making routine verification difficult.
Discover how spectral fingerprinting and portable near-infrared (NIR) technology enable fast, non-destructive fish species authentication, supporting transparency and safety across the seafood supply chain.

Near Infrared SpectroscopyNear-infrared (NIR) spectroscopy measures the interaction of near-infrared light with a sample, including transmission, reflectance and absorbance, facilitating the identification of analytes. Measurements can be conducted using a Fourier-transform near infrared (FT-NIR) spectrometer, while there are also UV-Vis- NIR spectrophotometers that measure a broader spectrum of wavelengths.
