Combining Raman spectroscopy with scanning electron microscopy coupled to energy-dispersive X-ray spectroscopy to monitor the solubilization process it was possible to show that TMAH acts in the solubilization of proteins, amino acids and lipids. Besides, this investigation showed that the small residual masses of samples have organic and inorganic compounds. Accuracy tests indicated that such residues have not interfered in the analytical results (recovery between 90-95%). The obtained limits of detection (0.099 µg g -1) and quantification (0.33 µg g -1) are compatible with the detectability required for regulatory purposes. Linearity (R2 = 0.9925) and characteristic mass (13 pg) were also reported. Considering the set of 15 samples comercialized in Brazil, any Pb contamination was successfully observed and this was confirmed by the analysis of digested samples.eng--BrasilJournal of the Brazilian Chemical Society-Atomic absorption spectrometryChickenPbTMAHRaman spectroscopyAlkaline solubilization of chicken tissues monitored by Raman spectroscopy followed by Pb determination by GF AASinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleCampos, Náira SilvaOliveira, Marcone Algusto Leal deIzumi, Celly Mieko ShinoharaSousa, Rafael Arromba deinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFJFinstname:Universidade Federal de Juiz de Fora (UFJF)instacron:UFJFTHUMBNAILAlkaline solubilization of chicken tissues monitored by Raman spectroscopy followed by.pdf.jpgAlkaline solubilization of chicken tissues monitored by Raman spectroscopy followed by.pdf.jpgGenerated Thumbnailimage/jpeg1667https://repositorio.ufjf.br/jspui/bitstream/ufjf/9251/4/Alkaline%20solubilization%20of%20chicken%20tissues%20monitored%20by%20Raman%20spectroscopy%20followed%20by.pdf.jpg2c69ebaa6430780d55df077bd4ef5e9bMD54ORIGINALAlkaline solubilization of chicken tissues monitored by Raman spectroscopy followed by.pdfAlkaline solubilization of chicken tissues monitored by Raman spectroscopy followed by.pdfapplication/pdf1149975https://repositorio.ufjf.br/jspui/bitstream/ufjf/9251/1/Alkaline%20solubilization%20of%20chicken%20tissues%20monitored%20by%20Raman%20spectroscopy%20followed%20by.pdfb72d1b871c14a6216f902175935e1cf9MD51LICENSElicense.txtlicense.txttext/plain;
