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
Multiresidue determination of pesticides in surface water by SPE-HPLC-ESI and SPE-UPLC-ESI tandem mass spectrometry (MS/MS- triple quadrupole analyser). Author(s): ASSALIN, M. R.; QUEIROZ, S. C. do N. de; FERRACINI, V. L.; ROSA, M. A.; SOUZA, D. R. C. de Repository: BDPA Publication year: 2009
Comparison of matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) and PCR-RAPD as potential tools to differentiate SACCHAROMYCES CEREVISIAE strains. Author(s): AUGUSTINI, B. C.; CANOSSA, S.; MANFROI, V.; SILVA, G. A. da Repository: BDPA Publication year: 2015
Optimization of extraction conditions of volatile compounds of roasted beef by solid-phase microextraction. Author(s): FRANCISCO, V. C.; ALMEIDA, L. C.; BOGUSZ JUNIOR, S.; OIANO NETO, J.; NASSU, R. T. Aroma is one of the most important sensory attributes for acceptance by beef consumers. The first step in analysing the volatile compounds associated with this attribute is their extraction from the f... ... Repository: BDPA Publication year: 2020
