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
Comparative analyses of metabolic fingerprint integrated with cytotoxic activity and in silico approaches of the leaves extract of Spondias mombin L. and Spondias tuberosa Arr. Cam. from Northeast, Brazil. Author(s): GUEDES, J. A. C.; SANTIAGO, Y. G.; LUZ, L. dos R.; SILVA, M. F. S.; RAMIRES, C. M. C.; LIMA, M. A. C. de; OLIVEIRA, V. R. de; PESSOA. C. do Ó.; CANUTO, K. M.; BRITO, E. S. de; LIMA, M. F.; ALVES, R. E.; ZAMPIERI, D.; NASCIMENTO, R. F. do; ZOCOLO, G. J. Spondias species are a relevant source of natural-bioactive compounds in Brazilian folk medicine, and its biological potential has not been explored. Thus, this study aimed to determine the metabolomi... ... Repository: BDPA Publication year: 2020

Influence of Maturation Stages in Different Varieties of Wine Grapes (Vitis vinifera) on the Production of Ochratoxin A and Its Modified Forms by Aspergillus carbonarius and Aspergillus niger. Author(s): FREIRA, L.; GUERREIRO, T. M.; CARAMÊS, E. T. S.; LOPES, L. L.; ORLANDO, E. A.; PEREIRA, G. E.; PALLONE, J. A. L.; CATHARINO, R. R.; SANT'ANA, A. S. Ochratoxin A is the main contaminant mycotoxin of grapes produced mainly by Aspergillus niger and Aspergillus carbonarius. Besides, it is possible that the formation of modified mycotoxin occurs throu... ... Repository: BDPA Publication year: 2018
Verification of the selectivity of a liquid chromatography method for determination of stilbenes and flavonols in red wines by mass spectrometry. Author(s): SILVA, L. F. da; GUERRA, C. C.; FORESTI, A.; BERGOLD, A. M. Quantification of bioactive phenols, like stilbenes and flavonols (SaF), has been conducted to evaluate the nutraceutical potential of red wines. However, there is still a lack of full validated, fast... ... Repository: BDPA Publication year: 2016
A first look at the N- and O-glycosylation landscape in anuran skin secretions. Author(s): BARBOSA, E. A.; ALVES, G. S. C.; COURA, M. de M. A.; SILVA, H. de L. e; ROCHA, F. S. da; NUNES, J. B.; WATANABE, M. de S.; ANDRADE, A. C.; BRANDA, G. D. Amphibians secrete a complex array of molecules that shape their interactions with coinhabiting microorganisms and macroscopic predators. Glycans are a rapidly evolving and complex class of biomolecul... ... Repository: BDPA Publication year: 2022
