    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)
    (Sociedade Brasileira de Química, 2012) Bandeira, Raquel D. C. C.; Uekane, Thais M.; Cunha, Carolina P. da; Geaquinto, Luths R. O.; Cunha, Valnei S.; Caixeiro, Janaina M. R.; Godoy, Ronoel Luiz O.; Cruz, Marcus Henrique 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 and 3.0 ng g-1, respectively. Trueness, repeatability and intermediate precision values were 89.0-108.8%; 2.4-13.7%; 12.5-17.8%, respectively. To the best of our knowledge, this is the first report in which Ochratoxin A in roasted coffee is analysed by LC/ESI-MS/MS, contributing to the field of mycotoxin analysis, and it will be used for future production of Certified Reference Material.

    Review Coffee berry borer (Coleoptera: Curculionidae): An opening for fungi and toxins?
    (Editora UFLA, 2020) Rezende, Josiane Bueno de; Taniwaki, Marta Hiromi
    Coffee is one of the most consumed beverages in the world. Studies on coffee quality are important, because the occurrence of defective grains can affect its microbiological and sensory quality. The insect Hypothenemus hampei, when perfurating the fruits in the crop, causes coffee berry borer defects to reduce the weight of the grains and can also favor the entry of fungi, some of them toxigenic, that under ideal growth conditions are capable of producing toxins. The present article is a review of the general aspects of coffee, its defects, the coffee berry borer and the possible relationship with ochratoxigenic fungi and ochratoxin A production in coffee.
