Minced samples of cliff-fish from saithe during cold storage at 4 °C have been analyzed with fluorescence spectroscopy, and the amount of thiobarbituric acid reactive substances (TBARS) and total amount of volatile nitrogen (TVN) have been measured. Partial least squares regression models have been built between the fluorescence spectra and the chemical measured TBARS and TVN values. Both models were evaluated using full cross validation and test set validation. The correlation between the fluorescence spectra and TVN was 91% and the correlation between the fluorescence spectra and the TBARS was 79%, both using test set validation. The work has showed that fluorescence spectroscopy can be used as a rapid and non-destructive method for measuring TBARS and TVN in minced samples of cliff-fish from saithe with a high degree of accuracy.
