Potential use of visible reflectance spectra to predict lipid oxidation of rabbit meat

Furthermore, the suitability of five wavelengths (380, 420, 440, 580 and 600 nm), selected by PLSR, to discriminate meat samples according to storage times, was also investigated by discriminant analysis performed on a new data set, composed of the second derivative spectral data, measured on meat samples (n = 900), which were collected from local supermarkets at 3 different storage times (1, 3 and 6 days). Overall accuracy was 82%, thus corroborating the feasibility of using visible spectroscopy to assess the qualitative decay in rabbit meat.
