Resumo
In 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.
