Freshness assessment of fish fillets by visible and nearinfrared (vis/nir) spectroscopy l [electronic resource]. تقدير درجة طزاجة الاسماك باستخدام التحليل الطيفي في المدي المرئي والقريب من التحت الحمراء. p.288 -304. Includes references. This study was carried out to examine the ability ofvisible/near infrared (VIS/NIR) spectroscopy to predict the freshness of Catfish (Icatalurus punctatus) and Atlantic halibut (HiPPoglossus hippoglossus) fillets for _ estimating their storage time. The fillets of both species were stored dt40C in vacuum-packages. Spectral properties of individual fillets were extracted using VIS/NIR spectroscopy throughout a period of 16 days to cons/l1/ct models for predicting storage time offillets. Multivariate data analysis using partial least-squares regression (PLSR) was used to determine the correlation between NI!l/VIS spectra and storage time. The correlation coefficient between actual and predicted storage time was 0.998 and 0.996. and the root mean square error estimated by cross validation (RMS£CV) was found 10 be 1.33 and 1.89 days for catfish and halibut respectively. The accuracy, rapidity and the low complexity ofthe obtained models suggested spectroscopy technique as a promising method for rapid assessment of the degree offreshness in fish fillets by identifying their storage period.
