Chemical qualities of black tea of Misiones-Argentina and a derived product (bt) for exportation
Argentina exports about 95% of its tea production, around 95% of its production being concentrated in the province of Misiones. Black tea in mostly exported in bulk and a tea product commonly known as BT (Black Tea). The purpose of this work was to study the chemical quality of black tea and BT prod...

| description | Argentina exports about 95% of its tea production, around 95% of its production being concentrated in the province of Misiones. Black tea in mostly exported in bulk and a tea product commonly known as BT (Black Tea). The purpose of this work was to study the chemical quality of black tea and BT product produced in Misiones and for exportation. The possibility of distinguishing them chemically was also studied. For this purpose, a total of 213 sample testing protocols admitedd at the Industry General Direction of the Province of Misiones were used in the period February 1999 - June 2009. The results indicate that chemical quality of these products has been maintained over time and can be distinguished chemically. Their differentiation taking into account only the variables caffeine and crude fiber is suggested. Contents of aqueous extract outweigh the requirements of the Argentine Food Code for black tea. |

Argentina exporta aproximadamente el 95% de su producci´n de té concentrando alrededor del 95% de su producción en la provincia de Misiones. Se exporta principalmente té negro a granel y un producto de té conocido comúnmente como BT. El trabajo consistió en estudiar la calidad química de ambos productos producidos en Misiones y destinados a exportación. Asimismo, se estudió la posibilidad de diferenciarlos químicamente entre sí. A tal fin, se utilizaron un total de 213 protocolos de análisis de muestras ingresadas a la Dirección General de Industria de la Provincia de Misiones en el período febrero 1999 - junio 2009. Los resultados indican que la calidad química de estos productos se ha mantenido en el tiempo y pueden diferenciarse químicamente. Se sugiere diferenciarlos teniendo en cuenta sólo las variables cafeína y fibra cruda. Los contenidos de extracto acuoso superan ampliamente lo exigido por el Código Alimentario Argentino para té negro.
