Bolivia podría ser considerado un país potencial en la producción de polvo de Tara, la producción en Bolivia está localizada en valles de altura, 2000 m o más sobre el nivel del mar, en comparación con otros sitios de producción a nivel mundial, sin embargo, no existen estudios sobre la influencia de la altura en sus propiedades fisicoquímicas ni sobre el contenido de sus taninos. En el mercado mundial Perú es el mayor exportador de polvo de Tara, por lo que existen muchos estudios locales sobre este producto, particularmente sobre sus propiedades químicas.
Correspondent author: Tara (Caesalpinia spinosa), Tannins, Condensed Tannins, Gallic acid, Leather Tanning.Įl polvo de Tara se obtiene por molienda de las vainas secas de la planta conocida como Tara ( Caesalpinia spinosa), se caracteriza por el alto contenido de Taninos, que es de gran utilidad en la industria de curtiembres, en el denominado curtido vegetal, su uso ha sido extendido en los últimos años, debido a que es una técnica amigable con el medio ambiente. The results suggested that Tara powder obtained from high altitude samples presents higher values of total tannins compared to those produced at a lower height above sea level, as a result of greater solar ultraviolet radiation in the production of tannins, more studies are necessary to establish such influence. In the present research, the chemical properties and the tannin content of the Bolivian Tara powder, from the department of Chuquisaca, localities of Icla, Tomina, Mojocoya Yacambé and Mojocoya Redención pampa were studied. However, there are no studies on the influence of altitude on its physicochemical properties and the content of its tannins. Bolivia could be considered a potential country in the production of Tara powder, the production in Bolivia is located in high altitude valleys (over 2000 masl) compared to other production sites worldwide. In the world market, Peru is the largest exporter of Tara powder and there are many local studies on this product.
Tara powder is obtained by grinding the dry pods of the plant known as Tara( Caesalpinia spinosa), it is well known for its high content of tannins, which gives it great utility in the tanning industry, in the so-called vegetable tanning, its use has been widespread in recent years, because it is an environmentally friendly technique.
