Process for reducing contamination by distillation of ethyl carbamate in alcoholic beverages

摘要

Process for reducing contamination by distillation of ethyl carbamate in alcoholic beverages. The contamination of the Brazilian spirit by ethyl carbamate, potentially carcinogenic substance, is considered an obstacle to the export of the drink.The copper is involved in the reactions of the formation of ethyl carbamate and its replacement by stainless steel in the distillation equipment, in order to avoid the formation of this compound produces a drink bad sensory quality, due to the presence of dimethyl sulfide.The reduction in the concentration of sulfur compounds in the final product can be obtained by the introduction of a copper device (patent nu00ba8206688) in the interior of the spire of alembic of stainless steel.It is therefore appropriate to verify the efficiency of the use of other forms of catalysts which can not only reduce the levels of ethyl carbamate, also play other catalytic actions that provide the obtaining of a distillate with good sensory quality.Silver is the noble metal of greater industrial use and for the account of their properties catatu00edticas is ideal for use as a catalyst in reactions of oxidation. The object of the present invention includes a process that involves the use of silver in the distillation of alcoholic beverages, such as the CAC Hau00e7a, which reduces contamination by ethyl carbamate in the final product.
