Laser induced breakdown spectroscopy for quantification of sodium and potassium in minced beef: a potential technique for detecting beef kidney adulteration. Analytical Methods, vol. 9, pg. 3314-3322. doi:10.1039/C7AY00757D Authors Y. Dixit, Maria Piedad Casado-Gavalda, R. Cama-Moncunill, X. Cama-Moncunill, Maria Markiewicz-Kȩszycka, Patrick Cullen, and Carl Sullivan Beef is a rich source of important minerals, with potassium (K) being the most abundant mineral quantitatively except in cured meats where Na from the added salt predominates. This study evaluates the potential of LIBS for quantification of the sodium (Na) and potassium (K) contents of minced beef as a potential method of detecting beef kidney adulteration. Additionally, the study aims at demonstrate the ability of LIBS to provide spatial mineral information of minced beef. A LIBS system was employed to collect spectral information of adulterated minced beef samples. Atomic absorption spectroscopy (AAS) was used to obtain reference values for Na and K. The chemometric technique of partial least squares regression (PLSR) was used to build the prediction models. Spatial mineral maps of minced beef samples were generated based on the predicted percentages of Na and K. The models for Na and K yielded calibration coefficients of determination ( 2 )
