Method for the analysis of ethyl carbamate in alcoholic beverages by capillary gas chromatography

Investigation of ethyl carbamate levels in some fermented foods and alcoholic beverages

“…There was a similarly wide range of concentrations in the liqueur samples examined, with values from 9 μg|l up to 439 μg|\. The highest concentration occurred with a cherry liqueur, and the result was confirmed by mass spectrometry using the selected ion monitoring at m I z 61, 62 and 74 as described previously (Dennis et al 1986). Ethyl carbamate was consistently detected in wine and port in concentrations of up to 18 μg|\ and 21 μg|\ respectively.…”

“…(Conacher et al 1987, Cairns et al 1987, nitrogen-phosphorus thermionic (Bailey et al 1986, Baumann and, flame ionization (Andrey 1987, Van Ingen et al 1987, chemiluminescence (Dennis et al 1986) and mass spectrometry (Aylott et al 1987, Cairns et al 1987, Mildau et al 1987. Application of these methods has resulted in a growing body of data on ethyl carbamate levels in alcoholic beverages.…”

Carbamato de etila em bebidas alcoólicas (cachaça, tiquira, uísque e grapa)

“…Em março de 1990, o FDA ("U. S. Food and Drug Administration") publicou nota 11 na qual os produtores de uísques americanos se comprometeram, a partir daquela data, a limitar o teor de carbamato de etila em 0,125 mg L -1 . Muitas metodologias analíticas vêm sendo propostas para a determinação de carbamato de etila em alimentos, todas empregando a cromatografia a gás com diferentes dispositivos de detecção [12][13][14][15][16][17][18][19] . Em função das baixas concentrações em que se encontra o carbamato de etila nas bebidas alcoólicas e da baixa sensibilidade que alguns detectores apresentam, faz-se necessário além da concentração das amostras uma etapa de desidratação dos extratos, geralmente com Na 2 SO 4 anidro 14,15,20 , tornando estes procedimentos morosos e mais susceptíveis a erros.…”

The use of yeast inoculation in fermentation for port production; effect on total potential ethyl carbamate

“…Extraction: All samples were extracted according to the method of Dennis et al (1986). Concentration was improved using the contents of 3 sachets of Extrelut column refill material (BDH) for each analysis and extracting 60 ml of diluted sample (1 in 4).…”
