Characteristics of microencapsulated Cucurbita pepo L. seeds oil formed by spray drying with maltodextrin and arabic gum

Abstract:

To elaborate an oral solid dosage form from Cucurbita pepo L. seeds from lipidic extract used in the treatment of benign prostatic hyperplasia, microencapsulation offers a solution to modify its physical conditions. Microcapsules obtained by spray drying using maltodextrin and arabig gum as encapsulant agent reached over 80% of encapsulation efficiency. The spherical form and the absence of pores on the surface of the microcapsules were verified by scanning electron microscopy. The particle size distribution was 34,28 μm of average diameter. The content of fatty acids and loss on drying was also determined, which proved the reproducibility on the results in laboratory and bank scales.
