Background: Consumers nowadays are engaged in a healthy lifestyle. The potential of
a nutritious fruit such as red flesh dragon fruit (Hylocereuspolyrhizus) has remained
largely underutilized. Red flesh dragon fruit is known to prevent colon cancer and
diabetes, to neutralize toxic substance such as heavy metals, to reduce cholesterol and
high blood pressure, and it is rich in phosphorus and calcium (Gunasenaet al., 2006).
Moreover, its peel has antibacterial property (Nurmahaniet al., 2012). It is also a good
source of fiber and pectin, and it is useful as a natural colorant (Jamilahet al., 2011).
Objective: This study aims to determine the consumer acceptability and physicochemical
content of the red flesh dragon fruit spread. Results: Sensory acceptability
was performed with 50 untrained consumers. The consumer acceptability test of the red
flesh dragon fruit spread is determined to be “very good”. The following physicochemical
analyses were performed: water activity (0.82 ± 0.01), pH (4.90 ± 0.10),
soluble solids (⁰Brix) (38.65 ± 0.31), moisture (46.63 ± 1.64), ash (0.68 ± 0.04) and fat
(0.44 ±0.09). Conclusion: Based on scores provided by 50 untrained consumers, red
flesh dragon fruit spread was deemed to be “very good.
