Bovine traceability is an important tool for the control of quality of the meat. It can assist in the identification of disease outbreaks, well-being of creation, fraud control and still ensure the origin of meat, adding value to the product in front of a consumer market increasingly demanding. This work was to objective the applicability of extractions employing tetramethylammonium hydroxide (TMAH) and scanning spectral m/z using inductively coupled plasma mass spectrometry (ICP-MS) for possible applicability using chemometrics in the control of traceability. For optimization of system a factorial design 24, with a total of sixteen experiments were performed with the use of NIST 8414 -Bovine Muscle Powder certified reference material. The sample mass varied from 0.050 (normalized -1) and 0.075 g (normalized +1). The volume of TMAH varied from 1.0 (-1) to 2.0 mL (+1) and the TMHA concentration changed 6.25 (-1) to 12.5 % (+1). The extraction time with agitation changed from 1 (-1) to 6 (+1) hours, in order to evaluate the recuperation of As, Ba, Co, Cd, Mo, Sr, Se and Pb using ICP-MS. Spectral scans were performed (0-300 m/z) with analytical blank and samples. After evaluation, the generates spectra will be used as the basis ~o propose the chemiometrics model (construction and validation) for forecast of samples of unknown origin. The sample preparation methodology has proved to >e adequate for the proposed procedure, which employ a huge number of samples. |
