Extraction of tannin by Acacia mearnsii with supercritical fluids
Studies were carried out on solvent and supercritical extraction to obtain natural tannins. The results showed that the best co-solvent to extract tannin with CO2 supercritical was water with a concentration of 5.0% and the best trap rinse solvent was methanol.<br>Neste trabalho foram utilizad...

| Summary: | Studies were carried out on solvent and supercritical extraction to obtain natural tannins. The results showed that the best co-solvent to extract tannin with CO2 supercritical was water with a concentration of 5.0% and the best trap rinse solvent was methanol.<br>Neste trabalho foram utilizados dois processos de extração de tanino vegetal: extração a quente em aparelho Soxhlet e extração com CO2 supercítico. Os resultados mostraram que o melhor co-solvente para extração de taninos com CO2 supercrítico foi a água na concentração de 5% e o melhor solvente para lavagem do trap foi o metanol. |
