Abstract

The physico-chemical, textural and color parameters and fluorescence spectra of aromatic amino acids and nucleic acids (AAA + NA), tryptophan residues, nicotinamide adenine dinucleotide (NADH) and vitamin A were scanned on sturgeon samples kept at 4 degrees C up to 12 days. Using the principal component analysis (PCA), the riboflavin and NADH spectra allowed clear differentiation between sturgeon samples according to their storage time. The best result was obtained by applying the common components and specific weights analysis (CCSWA) to the riboflavin and NADH data tables since better differentiation was achieved between the 4 group sturgeon samples aged: 2 days; 5, 6 and 7 days; 8 and 9 days and 12 days. The proposed methodology demonstrates the ability of CCSWA to evaluate sturgeon freshness level according to their storage time.
