Abstract—Tabtim fish (Oreochromis sp.) fillets were prepared with a size 100-150g/piece, individual packed into zip lock polyethylene bag and kept at 0, 5, and 10C up to 18 days. Total volatile basic nitrogen (TVB-N) and thiobarbituric acid-reactive substances (TBARS) were determined. The TVB-N and TBARS changes during storage were found to be adequately described by first-order reaction kinetics. The NIR spectra of TVB-N and TBARS in fish fillets (180 samples) were collected in the reflectance mode using NIRSystems 6500 at 25C. Results showed that the TVB-N and TBARS were 9.40-99.7mg/100g and 0.13-2.06mg malondialdehyde/kg, respectively. The spectra were in range of short-wavelength region (700-1000nm) and long-wavelength region (1000-2500nm). Consequently, the partial regression model with cross validation was created and the optimized model was done with full NIR spectra, short wavelength and long wavelength. It was found that the acceptable model of TVB-N was obtained with 750-1000nm with determination coefficient of calibration (R2cal) = 0.78. A model of TBARS showed good data with short wavelength (750-1000nm). Considering the obtained results, it is suggested that the TVB-N model could be used as a screening step to determine the TVB-N of Tabtim fish fillets.
