Abstract<i>Passiflora mollissima</i> (Kunth) L.H. Bailey is an exotic fruit native to South America, known as <i>taxo</i> in Ecuador. This paper characterizes its flavonoid and carotenoid composition and antioxidant capacity and evaluates the effect of the spray-drying process on its phytochemical composition and antioxidant capacity. A total of 18 flavonoid compounds, nine proanthocyanidins and nine flavan-3-ol monomers, were identified and quantified. Glycosides of (epi)-afzelechin stood out as the most abundant flavonoid. Three carotenoids were identified, with β-carotene having the highest concentration. The DPPH<sup>·</sup> and ORAC assay methods indicated a high antioxidant capacity. Furthermore, the bioactive content showed a positive and direct correlation with antioxidant capacity. On the other hand, the spray-drying process produced a stable phytochemical composition and antioxidant activity of <i>taxo</i>. These results demonstrate the potential applicability of microencapsulated <i>taxo</i> as a functional ingredient in the food industry.
