If you make in a EU country, then you can add a small % of the chemicals you mention such as sugar, or citric acid or glycerol - then you can export that to the US. In order to supplement the obtained results, GC-FID was used, which allowed for distinguishing among different vodka brands (Arbuzov and Savchuk 2002). J Anal Chem 57:428–433, CAS Each MOS-type sensor utilized in the electronic nose is selective with respect to a particular compound group, which yields a summary aroma profile characteristic for a given mixture. Phthalates are not chemically bound to plastic materials, which means they can migrate into the environment. Ethanol Vodka, by definition, is ethanol cut with water to at least 80 proof (40 percent purity). The vodka brands originating from Finland, Russia and Poland were among the analysed samples. Diluted with Water to get a 40% Alcohol to 60% Water ratio would be only stated as Vodka! Russian vodka is 40 percent ethanol and 60 percent water by volume (80 proof). 2013). 2 comments. The content of EC in Brazilian vodkas (Pereira et al. Each brand probably contains hundreds of additional types of molecules that give it a variety of flavors. Low concentrations of the compounds present in vodkas pose a big challenge for chemical analysts. It also has low detection limit (at the level of pg/L in solutions) due to highly efficient plasma ionization, and a wide linear range of calibration curves, which allows for determining trace and macro elements by a single measurement (Szpunar and Łobiński 1999; Vanhaecke and Moens 1999). IChF PAN, Warszawa, pp 34–36, Tsuchiya H, Ohtani S, Yamada K, Akagiri M, Takagi N, Sato M (1994) Determination of formaldehyde in reagents and beverages using flow injection. Among the detected groups of compounds were alcohols, aldehydes, ketones, esters, terpenes and aromatic compounds. Metal oxide semiconductor (MOS) type sensors are the most characteristic ones within this group. The ECD is a nondestructive detector which allows the determination of the concentrations of halogenated compounds at ppb-ppt level. Rectified spirit, also known as neutral spirits, rectified alcohol, or ethyl alcohol of agricultural origin is highly concentrated ethanol that has been purified by means of repeated distillation in a process called rectification.In some countries, denatured alcohol or denatured rectified spirit may commonly be available as "rectified spirit". The solution with a minimum ethanol content of 96 %, which is used to produce vodkas, also contains trace amounts of other compounds such as, esters, aldehydes, higher alcohols, methanol, acetates, acetic acid and fusel oil. Pour une vodka à base de pomme de terre, on les cuit afin de transformer l'amidon qu'elles contienne en sucres. alcohol, water and flavourants. 1999). Conductometric sensors are the most frequently utilized. The samples of whiskey, vodka, cognac and synthetic alcohols were analysed (Savchuk and Kolesov 2005). J Anal Chem 62:1013–1016, Savchuk SA, Kolesov GM (2005) Markers of the nature of ethyl alcohol: chromatographic techniques for their detection. Answer. Vodkas are not commonly analysed because of their matrix, which mainly consists of ethanol and water, and includes numerous organic and inorganic substances at low concentration levels. 2009). The obtained data were grouped by using canonical discriminant analysis (CDA) or classification binary trees (CBT) depending on the content of metals in samples. (2007) analysed different vodkas available on the Russian market with regard to the quality of spirit from which they had been made. Research on vodka identification also employs chromatography, for example, the study of commercial vodkas from the USA and Canada (Ng et al.
