Ethyl-carbamate determination by gas chromatography–mass spectrometry at different stages of production of a traditional Brazilian spirit
TL;DR: In this paper, gas chromatography-mass spectrometry was used to investigate the presence of methyl carbamate (EC) in the wine and in the fractions of the distillation process, as well as in the vinasse (the residue left after distillation).

TL;DR: Sixteen polycyclic aromatic hydrocarbons have been identified in Brazilian sugarcane spirits and consumers are at a greater risk of EC exposure from cachaça than from any other spirit.

TL;DR: In this article, structural and thermal stability of charge transfer complexes formed between EC as a donor with quinol (QL), picric acid (PA), chloranilic acid (CLA), p -chloranil ( p -CHL) and 1,3-dinitrobenzene (DNB) as acceptors were reported.

TL;DR: The results indicate that it is necessary for industry to optimize the wine frying conditions, such as temperature, time and cooling process in order to decrease EC formation.

TL;DR: In this paper, a simultaneous determination method was established by gas chromatography-triple quadrupole mass spectrometry (GC-MS/MS) for ethyl carbamate, acrylamide and chloropropanols in fermented products, flavoring and related foods.

TL;DR: In this article, the effect of a double distillation on the reduction of the carbamate content in sugar cane spirit was evaluated using gas chromatography/mass spectroscopy, and the results showed that the second distillation significantly reduced the amount of carbamate formed in the spirit.
Abstract: The aim of this study was to verify the effect of a double distillation on the reduction of the ethyl carbamate content in sugar cane spirit. Ethyl carbamate is a potentially carcinogenic compound normally present at critical levels in sugar cane spirit, constituting a public health problem and therefore hindering the export of this beverage. The ethanol, copper and ethyl carbamate contents were evaluated, using gas chromatography/mass spectroscopy, during a double distillation of the fermented sugar cane juice. The distillate fraction from the first distillation accumulated 30% of the ethyl carbamate formed. In the second distillation, the ethyl carbamate and the copper content increased during the process as the alcohol content decreased, and only 3% of the ethyl carbamate formed was collected in the spirit. Double distillation decreased the ethyl carbamate content in the sugar cane spirit by 97%. Copyright © 2012 The Institute of Brewing & Distilling

TL;DR: Early in the domestication of crop plants the cyanogenic species would have been relatively free of pests and competitive herbivores, as well as having good nutritional qualities, and thus ideal candidates for cultivation by the first farmers.

Abstract: IN a comprehensive joint investigation of the action of various compounds upon the growth of experimental tumours, attention was paid to that heterogeneous class of substances which have from time to time been reported as producing effects upon the mitotic cycle (“le syndrome mitoclasique”1) either in animals or plants Among these substances, the caryoclastic poisons of Dustin and his school2, ethyl phenylcarbamate ('phenylurethane') (I) and its
