Resumo: In this work the guariroba (Syagrus oleracea, Becc) was submitted to treatment with solutions containing peroxidase (POX) and poliphenoloxidase (PPO) inhibitors. Guariroba slices were immersed in 0.5, 0.8 and 1.0 % (p/v) citric acid, lactic acid and sodium bisulfite solutions, for 10, 15 and 20 minutes. The phenol contents and the enzymatic activities of POX and PPO were measured before and after treatment with the inhibitor solutions, as well as solution pH. The best results for both enzymatic inhibition and phenol content were obtained when the guariroba slices were treated with 1.0 % lactic acid solution for 10 minutes

Fatias de guariroba foram imersas em soluções de ácido cítrico, ácido láctico e bissulfito de sódio nas concentrações de 0,5, 0,8 e 1,0 % (p/v), por intervalos de tempo de 10, 15 e 20 min. As atividades de POX e PPO foram monitoradas antes e após o tratamento com as soluções de inibidores, bem como a concentração de fenóis e o pH das soluções. O ácido láctico, quando utilizado na concentração de 1,0 % por 10 min apresentou os melhores resultados, tanto para a inibição das enzimas quanto para a análise dos teores de fenóisUniversidade Estadual De Maringá2008-04-18info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciBiolSci/article/view/210810.4025/actascibiolsci.v25i1.2108Acta Scientiarum.
