• Resumen

  • The main objective of this work was to nd new applications to valorize olive stones (endocarpand seed). In order to improve knowledge on olive stones, the phenolic compounds concentrationof three varieties of Moroccan olive trees: Moroccan Picholine, Menara and Haouzian were studied.Olive stones of three varieties were characterized by Fourier Transform Mid Infrared Spectroscopy(FT-MIR). Total phenolic compounds are quanti ed a er solid-liquid extraction by an assay ofFolin-Ciocalteu. Moroccan Picholine stones (11.32 mg GAE/g DM) have a higher content of totalphenolic compounds than Haouzia stones (4.55 mg GAE/g DM) and Menara stones (3.56 mg GAE/gDM). ermogravimetric analysis indicates that up to 195°C; there is no degradation of the stones. e biocide performance on agar-agar was tested with decay fungi. Biodegradation studies show thatthe most interesting results are obtained with Moroccan Picholine stones. e presence of MoroccanPicholine in a particleboard panels improves the total resistance of the particleboard panels againstboth Coriolus versicolor and Coniophora puteana rot fungi.
