Rapid Near Infrared (NIR) spectroscopic technique was developed to measure peroxide value (PV), acid value (AV) and rho-anisidine value (AnV) of oxidized fish oil. A partial least squares (PLS) regression was used to developed calibration models from spectral data in first derivative and second derivative of log 1/T formats. The optimized calibration model of PV and AV were developed in the region of 1100-2200 nm, the AnV calibration model was developed in the region of 1100-2500nm. The correlation coefficient (R) of PV, AV and AnV were 0.96, 0.98 and 0.88 respectively. Calibration models were validated with the independent set samples. Root mean square error of prediction (RMSEP) of PV, AV and AnV were 1.44 meq/kg, 0.07 mgKOH/g and 6.88 respectively. The results of the paired t-test revealed that there was no significant difference between the NIR method and the standard method. According to the results obtained in this study, NIR spectroscopy is useful technique for measuring quality of fish oil.
