• Background/Aims: Gac fruit (Momordica cochinchinensis Spreng), tomato, and pineapple are local fruits from South East Asia local fruits that contain high bioactive compounds, such as carotenoids, phenolic, and vitamins. The objective of this research was to develop acceptable functional drink from gac fruit mixed with pineapple and tomato juice with good bioactive compound profile and sensory acceptance. Methods: Formulation of the functional drink was set using Design-Expert®7.00 software (DOptimal Mixture Design) using a mixture of 47% gac juice, 45% of tomato juice (TJ) and pineapple juice (PJ), and 8% fructose syrup, which resulted in eleven formulas. The experimental factors were %TJ and %PJ used in the formulation, while the responses analyzed were total polyphenol content (TPC), DPPH, FRAP and total carotenoid content. Results: Different concentrations of tomato and pineapple juice incorporated in the functional drink significantly affected all responses (p < 0.05). Formula with the highest concentration of pineapple juice showed the highest content of TPC (396.91 ± 10.12 μg GAE/mL), FRAP (330.23 ± 16.21 μmol AAE/100 ml), and DPPH (277.70 ± 11.30 μM Trolox). Formula with the highest concentration of tomato juice gave the highest value of total content (3748.65 ± 20.94 μg/100 mL). However, antioxidant capacity (DPPH and FRAP) of the samples was affected more by polyphenols as the bioactive compound rather than carotenoids. Optimization of the formula by transforming exponential equation based on output responses and importance generated three formulas with the highest desirability values for proximate analysis and sensory evaluation (9-scale hedonic test). Conclusions: The selected formula (47% gac juice, 39.33% pineapple juice, 8% fructose, 5.67% tomato juice), which was high in bioactive compound and well-accepted by consumers, was suitable to be developed as functional drink.
