Mass spectrometry screening of Arabica coffee roasting: A non-target and non-volatile approach by EASI-MS and ESI-MS. Author(s): ROSA, J. S. da; FREITAS-SILVA, O.; ROUWS, J. R. C.; MOREIRA, I. G. da S.; NOVAES, F. J. M.; AZEVEDO, D. de A.; SCHWAB, N.; GODOY, R. L. de O.; EBERLIN, M. N.; REZENDE, C. M. de Coffee roasting needs precise control and innovative techniques that are economically viable to monitor and improve its consistency. In this study, mass spectrometry was used as a tool to screen chemi... ... Repository: BDPA Publication year: 2016
Development and validation of a method for the analysis of Ochratoxin A in roasted coffee by liquid chromatography/electrospray-mass spectrometry in Tandem (LC/ESI-MS/MS). Author(s): BANDEIRA, R. D. C. C.; UEKANE, T. M.; CUNHA, C. P. da; GEAQUINTO, L. R. O.; CUNHA, V. S.; CAIXEIRO, J. M. R.; GODOY, R. L. O.; CRUZ, M. H. C. de la. A method using LC/ESI-MS/MS for the quantitative analysis of Ochratoxin A in roasted coffee was described. Linearity was demonstrated (r = 0.9175). The limits of detection and quantification were 1.0... ... Repository: BDPA Publication year: 2012
Screening of alkaloid-producing endophytic Penicillium strains from Amazon medicinal plants by Electrospray Ionization Mass Spectrometry (ESI-MS) and Principal Component Analysis (PCA). Author(s): SILVA-FILHO, F. A. da; SOUZA, M. M. M. de; REZENDE, G. O.; SILVA, F. M. A. da; CRUZ, J. C. da; SILVA, G. F. da; SOUZA, A. D. L. de; SOUZA, A. Q. L. de The genus Penicillium is among the most promising alkaloid-producing fungal and therefore plays an important role in terms of producing molecules with biotechnological potential. Thus, in order to ide... ... Repository: BDPA Publication year: 2021
