Resumen
El Pisco, licor destilado a partir del jugo fermentado de uva se produce en el Perú; según
Norma Técnica Peruana NTP 211-001-2002 (2); en alambiques o falcas de cobre. El
producto obtenido presenta en su composición trazas de cobre presente como Cu++
arrastrados desde el equipo, lo que a largo plazo es dañino para el consumidor, por lo que
se requiere remover el cobre disuelto en el Pisco.
Usando el método de adsorción; de esta manera se evita desechar determinados lotes de
Pisco conteniendo cantidades excesivas de cobre; por encima de 2 mg/I (4); lo cual se
traduciría en pérdidas económicas por parte de los pequeños productores, que en su
mayoría son artesanales se desea lograr eliminar el cobre sin que cambie sus
características organolépticas; haciendo agradable y apto para su consumo.
Se realizaron análisis cuantitativo de cobre en muestras de Pisco; provenientes de los
centros de destilación más representativos del valle de Ica; antes y después de la remoción
de cobre por el método de adsorción utilizando - resina de tipo Amberlite, Cationica
1R120-H, R&H (1), a fin de verificar la eficiencia del método; con estos resultados de
análisis y aplicando métodos estadísticos para un valor de confianza de 95% podemos
determinar que si es posible.
Pisco, liquor distilled from fermented grape juice, is produced in Peru according to Peruvian Technical Standard NTP 211-001-2002 (2), in copper stills or falcas. The product obtained has in its composition traces of copper present as Cu ++ dragged from the equipment, which in the long term is harmful to the consumer so it is necessary to remove the dissolved copper in the Pisco. Using the absorption method; in this way, it is avoided to discard certain batches of Pisco containing excessive amounts of copper; above 2 mg/I (4); This would result in economic losses on the part of small producers, most of whom are artisanal, the desire to eliminate copper without changing its organoleptic characteristics; making it pleasant and suitable for consumption. Quantitative copper analysis was performed on Pisco samples; from the most representative distillation centers of the Ica Valley; before and after the removal of copper by the adsorption method using - Amberlite type resin, Cationic 1R120-H, R & H (1), for check the efficiency of the method; With these analysis results and applying statistical methods for a confidence value of 95% we can determine that it is possible.
