Attenuated total reflectance Fourier transform infrared spectroscopy has been used to characterize processed meat products. Proteins were estimated through the amide I band centered at 1650 cm-1 and lipids through the carbonyl stretching band at 1735 cm-1.
Estimations of protein/lipid ratios were obtained by dividing the area under the 1650 cm-1 band by the area under the 1735 cm-1 band. These protein/lipid ratios correlated well with those obtained for the same samples using conventional chemical analysis. Attenuated total reflectance Fourier transform infrared spectroscopy is therefore a quick and analytical technique with the advantage over other procedures of being non destructive and which can be used to assess the quality of processed meat products.
