Miracle berry is known for its unique characteristic of modifying sour flavours to sweet. Twelve phenolics
were identified and quantified in the miracle berry flesh at a level from 0.3 for kaempferol to 17.8 mg/
100 g FW for epicatechin. Lutein and a-tocopherol were also quantified at a level of 0.4 and 5.8 mg/
100 g FW, respectively. The TP and TF contents were 1448.3 GA and 9.9 QR mg Equiv/100 g FW for the
flesh, respectively, compared with 306.7 GA and 3.8 mg QR mg Equiv/100 g FW of the seeds. The free radical
scavenging and reducing percentage of the flesh extract was 96.3% and 32.5% in DPPH and ABTS
assays, respectively. Additionally, the flesh extract had a high FRAP of 22.9 mmol/100 g. It significantly
inhibited the oxidation of PUFA in fish oil as well. Thus, miracle berry could also serve as an antioxidant-rich
fruit to provide health promoting function.
