The majagua flower (Talipariti elatum Sw.) is rich in bioactive compounds with antioxidants, neuroprotective, antimicrobial, anticancer, and cardioprotective activity, although they are highly sensitive to degradation during processing and storage. To stabilize them, microcapsules were prepared by electrospinning encapsulation using zein as a protective matrix in three extract concentrations (10, 20, and 30% w/w). FT-IR analysis confirmed zein's ability to encapsulate the extract's bioactive compounds. The morphology of the particles was evaluated by SEM, and the release of compounds was consistent with the Peleg and Korsmeyer-Peppas models. The highest encapsulation efficiency was achieved with 20% w/w (~69%), showing uniform particles and controlled release by diffusion. These results confirm that electrospinning with zein effectively protects the bioactive compounds of the majagua flower, ensuring sustained release and potential biological functionality, with applications in pharmaceutical and nutraceutical formulations.
