Abstract

La presente invencion se relaciona con un metodo novedoso para recuperar y reciclar taninos activos a partir de licores curtientes vegetales agotados. Utilizando un alcohol de bajo peso molecular como el agente de extraccion, se produce una fraccion alcoholica o un precipitado que contiene taninos activos extraidos, y deja virtualmente todos los no taninos en la fase acuosa del licor curtiente agotado. Los metodos y mezclas quimicas resultantes de la presente invencion tienen una variedad de usos y aplicaciones. El metodo puede aplicarse a licores curtientes vegetales agotados madurados, o producidos recientemente. Los metodos son aplicables ademas, a las formas secas de los licores curtientes agotados, a traves de la reconstitucion acuosa del ReTan seco, seguida por la extraccion con alcohol. La mezcla quimica recuperada, contiene taninos recuperados, los cuales pueden reciclarse a traves de la combinacion con licores curtientes frescos, para formar un licor curtiente mejorado.
