Lyophilization is a preservation technique that preserves the characteristics of the product in a particular way, a fact that is not always the case in other techniques. The objective was to produce the lyophilized powdered extract of moringa seeds and to determine their physical and physicochemical characteristics. The work was conducted at the Laboratory of Storage and Processing of Agricultural Products, Federal University of Campina Grande, Paraíba. The experimental design was completely randomized, composed of four treatments and three replicates; using a Liotop® L101 benchtop freeze drier, in which the apparent and actual density, porosity, compacted density, compressibility index, Hausner factor, solubility, color, water content and activity, ashes, titratable total acidity, pH, proteins, lipids and carbohydrates. The results showed, for the dilutions studied, the formulation of the pulp for the production of the lyophilized powder, the dilution of 50 mL as the best, because it presented higher yield, real density, porosity, lower compressibility index, Hausner factor, water, higher amounts of proteins, lipids and lower darkening index.
