Unmodified cellulose filter paper, a sustainable and affordable sorbent for the isolation of biogenic amines from beer samples

While current trends in Green Analytical Chemistry aim at reducing or simplifying sample treatment, food usually comprises complex matrices where direct analysis is not possible most cases. In this context, treatment plays a pivotal role. Biogenic amines are naturally formed many foodstuffs due to the action of microorganisms, while their presence has been associated with adverse health effects. work, extraction seven biogenic (cadaverine, histamine, phenylethylamine, putrescine, spermidine, spermine, and tyramine) from beer samples simplified using laboratory filter paper as sorbent without any further modification. The eluates by infusion mass spectrometry reduces time analysis, increasing throughput. This simple but effective method enabled determination analytes limits detection low 0.06 mg L?1 relative standard deviations better than 11.9%. suitability assessed analyzing eight different types beers addition method.
