Abstract

There have been concerns regarding the use of artificial food colorant, triggering the food industry to develop natural food colorant with nutraceutical properties, which could be solved by anthocyanins. A series of studies to evaluate the potency of harendong bulu (Clidemia hirta (L.) D. Don) fruit as the source of anthocyanin was conducted. First, the selection of time (30, 60, and 90 minutes) and temperature (30°C, 45°C, and 60°C) of aqueous extraction at pH 1. Second, the evaluation of anthocyanin characteristics and stability of the extract at pH 1, 3, 5, 7, and 9. Extraction at 60ºC for 30 minutes gave the best result with 43.81 ± 2.99 mg/L total monomeric anthocyanin and 1.31 ± 0.12 g/L phenolic compound as gallic acid equivalent. C. hirta expresses red color at pH 1 and 3. At pH 5, it showed a unique characteristic by expressing deep blue color at pH 5. However, the high browning index and low color stability at the pH have not supported the extract as the potential food colorant. The extract exhibited the best anthocyanin quality and stability at pH 1 by showing bright red color, low browning index, and high color stability (t0.5 = 126.85 d). The best performance of C. hirta at the range of food pH was at pH 3. At the pH, even though the 50% monomeric anthocyanin disappeared in 5.7 days, C. hirta retained its 50% color for 21 days at room temperature. Hence, C. hirta showed its promising performance as the red colorant for high acidic food products.
