Abstract In this study, the stability of the bioactive compounds from camu-camu and jambolan mixture was evaluated, and a juice blend formulation based on its sensorial properties was established. The stability of three juice formulations with camu-camu/jambolan/water (w:w:w), 37.5:12.5:50 (JB); 37.5:0:62.5 (CJ) and 0:12.5:87.5 (JJ) was evaluated. Additionally, the bioactive compounds and sensory acceptance were performed in six juice formulations with camu-camu/jambolan: 12.5:37.5 (F1); 17.5:32.5 (F2); 22.5:27.5 (F3); 27.5:22.5 (F4); 32.5:17.5 (F5) and 37.5:12.5 (F6). The stability of the anthocyanins in the JB formulation was ensured for 5 days of storage at 25 °C. First-order reaction kinetics described the degradation of anthocyanins during 10 days of storage. The internal preference map analysis evidenced two groups: one formed by the formulations F1 and F2 and the other by F3, F4, F5 and F6. Sensory analysis showed that the formulation with the lowest concentration of camu-camu (F1) presented the highest sensory acceptance rate (80.4%), high bioactive compounds contents: 23.04 mg anthocyanins.100 mL-1, 353.32 mg ascorbic acid.100 mL-1, 892.06 mg phenolic compounds.100 mL-1, and high antioxidant capacity (3667.78 mM ET.100 mL-1). The results shows that juice blend with camu-camu/jambolan 12.5:37.5 (F1) have a good acceptance and high bioactive compounds content.
