AB  - Butter adulteration with margarine continues to be a threat for consumers; therefore, new rapid analytical tools are needed for quality control/quality assurance purposes. In this study, we used Raman spectroscopy coupled with partial least squares regression to quantify butter adulteration with margarine. The main difference between Raman spectra of butter and margarine comes from two bands associated to C=C double bond (1656 and 1268 cm(-1)) and the band associated to phospholipids' choline group (973 cm(-1)). The intensity of these peaks decreases with a decreasing margarine content. The coefficient of determination (R (2) = 0.994) and root-mean-square error of prediction (RMSEP = 2.754) display very good overall model performance. The sample preparation procedure that we employed was notably simplified compared to previous studies. This confirms that Raman spectroscopy can be effectively applied to quantify butter adulteration with margarine and further indicates that simplification of the analysis procedure is possible. These results could aid the efforts for implementation of this technique in routine rapid quality analysis of butter.

AB  - Since fishery products represent an important and globally growing food resource, there is also an increased incidence rate of intentional mislabelling of fish products and restaurant frauds globally. In the present study, Raman spectroscopy, as a fast and non-invasive technique, was applied using a laser at a wavelength of 532 nm for the classification of deep frozen fish fillets. Without any preparation, muscle tissue of 12 fish types was analysed with a Raman device, and according to a hierarchical cluster analysis of their spectra, three groups were identified: (1) the carotenoid group, fish from salmonid family; (2) the freshwater group, fish that was reared in fresh or brackish water; and (3) the saltwater group, fish reared in saltwater. Thus, it is demonstrated that Raman spectroscopy can be used as a direct, non-expensive and fast screening method before proceeding with standard methods for the identification of fish fillets.
