Application of FT NIR spectroscopy in the determination of basic chemical composition of pork and beef
Mlcek, J. | Sustova, K. | Simeonovova, J.
Pork and beef samples were analysed on an FT NIR Nicolet Antaris device in a reflectance regimen. Reference results from classical analyses were used for the calibration of the device in order to determine moisture content and concentrations of proteins and fat. Calibration models were created using partial least squares algorithm and verified by cross-validation. High correlation coefficients of calibration were calculated (fat 0.998; protein 0.976; water 0.994), and subsequently of validation as well (fat 0.997; protein 0.970; water 0.993). Very low standard deviations of the calibration and validation were determined. No statistically significant differences between the reference and predicted values of determination were detected in Z-test. The NIR spectroscopy has a high potential to replace the expensive and time demanding chemical analysis of meat composition.
