Summary

The freshness as storage time in ice of cod (Gadus morhua) and salmon (Salmo salar) was estimated by visible/near infrared (VIS/NIR) spectroscopy. The correlation between spectral data and storage time was modeled by multivariate statistics. For cod, the best-fit model was found by using the visible wavelength range, giving correlation of prediction of 0.97 with an error value of 1.04 d. For salmon, the best-fit model was made with data from the NIR range giving correlation of prediction of 0.98 and an error value of 1.20 d. Hence, VIS/NIR spectroscopy proved useful for the evaluation of fish freshness.
