Procedimento eficiente na inibição do escurecimento de guariroba (Syagrus oleracea, Becc) durante processamento e armazenamento. Acta Scientiarum. Biological Sciences, Maringá, v. 25, n. 2, p. 189-193, 2003.1679-9283e- 1807-863Xhttp://repositorio.bc.ufg.br/handle/ri/16106In this study the guariroba (Syagrus oleracea, Becc) was submitted to a blanching procedure that was able to inactive the peroxidase (POD) and polyphenoloxidase (PPO) enzymes. The treatment consisted of immersing guariroba slices in a pre-processing solution containing a solution of 1.0% (p/v) of lactic acid during 10 minutes, followed by heating in solution of NaCl 2.5% (p/v) for 15 minutes. This treatment was effective for enzymes inactivation, measured by enzyme activity tests and color development and luminosity tests, allowing the storage of guariroba in polyetilene sacks, at 8oC, for 60 days. We also investigated the influence of post harvest time on economic viability of this plant, which allowed us to suggest this plant processing at a maximum time limit of three days after harvest.porAcesso AbertoPeroxidaseProcessamentoPolifenoloxidaseEscurecimentoGuarirobaPeroxidasePoliphenoloxidaseGuarirobaDarkness inhibitionProcessingArtigo10.4025/actasciagron.v25i2.1744
