Commercialization of Mauritia flexuosa (buriti) fruits in Brazil is at an early stage. Herein, we evaluate the nutritional value pulp, peel and endocarp samples from buriti fruits, perform macroscopic microscopic evaluations analyze their physicochemical properties. Size mass, pH, sugar protein contents, soluble/insoluble fiber, total titratable acidity energy were analyzed. Mineral profiling was performed by dispersive X-ray fluorescence spectrometry, fatty acids phytosterols determined gas chromatography-mass spectrometry. Samples also submitted to differential scanning calorimetry coupled a thermal analyzer, microstructure, morphology, surface viscosity evaluated electron microscopy (SEM) diffraction (XRD) with copper radiation. Rheological behavior studied. Lyophilized pulp had higher content minerals, proteins, carbohydrates than natura pulp. its by-products showed suitable yields (>17.31%) low w, potassium, manganese monounsaturated acid contents. Peels elevated amounts saturated polyunsaturated (β-sitosterol stigmasterol), endothermic behavior. The reductions calcium, magnesium ranging 18.5 22.7% observed following lyophilization. Drying processes generated semi-crystalline powders. Both peels contained insoluble fiber lower contents sugars. Similar results obtained morphological analysis, XRD analysis. Pulp exhibited pseudoplastic non-Newtonian behavior, flow index values 1, while presented dilatant behaviour. Thus, characterization by-products, such as endocarp, are essential support scientific research exploration new sustainable products. Processing conservation techniques, like lyophilization, maintain good quality bioactive compounds whole can be used extend shelf life, preserve alimentary characteristics provide wider purposes availability. Such parameters may generate income food security for local regional communities.
