Current trends in Green Analytical Chemistry focus on simplifying sample treatment, but food matrices are often too complex for direct analysis. Biogenic amines, formed naturally in food products, have health implications. This study simplified the extraction of biogenic amines from beer samples using laboratory filter paper and direct infusion mass spectrometry, leading to efficient analysis.
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 in most cases. In this context, sample treatment plays a pivotal role. Biogenic amines are naturally formed in many foodstuffs due to the action of microorganisms, while their presence has been associated with adverse health effects. In this work, the extraction of seven biogenic amines (cadaverine, histamine, phenylethylamine, putrescine, spermidine, spermine, and tyramine) from beer samples has been simplified using laboratory filter paper as sorbent without any further modification. The analysis of the eluates by direct infusion mass spectrometry reduces the time of analysis, increasing the sample throughput. This simple but effective method enabled the determination of the analytes with limits of detection as low as 0.06 mg L-1 and relative standard deviations better than 11.9%. The suitability of the method has been assessed by analyzing eight different types of beers by the standard addition method. (c) 2021 The Author(s). Published by Elsevier B.V.
