1. Determination of Ethyl Carbamate in Commercial Sweetened Sugar Cane Spirit by ESI-MS/MS Using Modified QuEChERS and 18-Crown-6/Trifluoroacetic Acid Spiking Additives
A fast, sensitive, and selective direct injection electrospray tandem mass spectrometry (DI ESI MS/MS) method that is able to quantify ethyl carbamate in commercial sweetened sugar cane spirit is described. The preparation method uses a modified QuEChERS (quick, easy, cheap, effective, rugged, and safe) with potassium carbonate added to sweetened sugar cane

2. Two Years Monitoring of Ethyl Carbamate in Sugar Cane Spirit from Brazilian Distilleries
This paper describes the monitoring of ethyl carbamate concentration in sugar cane spirit from industrial distilleries in Brazil. In total, 18 distilleries from Minas Gerais and São Paulo states were evaluated, with, a total of 336 samples from August 2017 to August 2019. The ethyl carbamate was analyzed using a previously validated mass spectrometric metho

3. DETERMINAÇÃO DE SÓDIO EM CACHAÇA POR ESPECTROMETRIA DE EMISSÃO ATÔMICA: EFEITO DAS PROPRIEDADES FÍSICO-QUIMICAS DA SOLUÇÃO
The use of samples from students quotidian can get their attention for teaching contents to be presented. We have already presented a series of simple experiments demonstrating the use of flame atomic emission spectrometry in the determination of cations in samples present in our day life. Here sodium is determined in cachaça (sugar cane spirit), a very pop

4. An alternative method for the simultaneous determination of copper and lead for quality control of sugar cane spirit using a nanotube-based sensor
Um método eletroanalítico foi desenvolvido para determinação simultânea de íons cobre e chumbo em cachaça empregando eletrodo de pasta de carbono modificado com ácido ascórbico e nanotubos de carbono (CPE-AaCNT). A técnica de voltametria de onda quadrada (SWV) com redissolução anódica foi empregada e otimizada com relação aos seguintes parâme

5. As Novas ruralidades e as recentes alternativas da agricultura familiar no município de Itapiranga (SC)
The new rurality is creating job opportunities and income in family farming in the municipality of Itapiranga/SC, which must be analyzed. Have been numerous initiatives in this direction, such as recreation sites, agro-ecological gardening, farming, forestry, fish and small agro-industries derived from cane sugar (molasses, brown sugar and "Schmier"), rural

7. Formação de carbamato de etila em aguardentes recém-destiladas: proposta para seu controle
The commercial sugar cane spits redistillation decreased up to 92,5% their ethyl carbamate (EC) original content. Quantitative analysis of EC in 15 samples of sugar cane spirit (alembic and column), fresh distilled and collected in situ demonstrated that the urethane is formed mostly after distillation. The average time to achieve the complete EC formation i

8. Desenvolvimento de estratégias analíticas usando espectrometria de absorção atômica para avaliar a composição de copos de liga peltre e lixiviação de cádmio, chumbo e antimônio
In this work it was developed different analytical methods using atomic absorption spectrometry (AAS). Firstly, it was developed a method for the sequential determination of antimony and lead, in pewter sample, using high resolution continuum source flame AAS. The results showed that samples contain lead. This affirmation goes against manufacturer which says

9. Synchronous scanning phosphorimetry for the selective determination of chrysene: a metrological study
Room-temperature phosphorimetry was used to quantify trace levels of chrysene in sugar-cane spirits and in fish bile. A selective phosphorescence enhancer (AgNO3) and synchronous scanning allowed the detection of ng amounts of chrysene. Accuracy (113 ± 17%) and selectivity was evaluated using the CRM-NIST-1647d - Priority Pollutant Polycyclic Aromatic Hydro

10. Composição química da aguardente de cana-de-açúcar ao longo do processo de dupla destilação em alambique simples / Chemical composition of sugar cane sugar spirit during the process of double distillation in pot still
A cachaça é a segunda bebida alcoólica mais consumida no Brasil e vem ganhando espaço no mercado devido aos esforços do setor produtivo e também a ações governamentais. A produção de brasileira de cachaça é estimada em 1,7 bilhão de litros, sendo que cerca de 400 milhões são produzidas em alambiques. A cadeia produtiva não é tecnologicamente

11. Teores de carbamato de etila em aguardentes de cana e mandioca: parte II
Herein, we report the concentration of ethyl carbamate (EC) and copper in 380 samples of sugar-cane spirit and 45 samples of manioc spirit as determined by GC-MS and FAAS respectively. The cyanide content determined spectrophotometrically is reported for the manioc spirit. Sugar cane spirit produced by alembic distillation (70,0 µg L-1) shown a lower conten

12. DeterminaÃÃo dos teores do de carbamato de etila e de acroleÃna em aguardentes de cana produzidas em Minas Gerais / Determination of ethyl carbamate, acrolein in sugar cane spirits produced in Minas Gerais
Sugar cane spirit is obtained by means of natural fermentation process of the sugar cane juice, there being some critical points in the steps due to the presence of contaminant microorganisms and undesirable substances that can interfere in the production and the quality of the beverage. In addition to ethanol and water, the beverage contains in lesser conce
