Dragon fruit is a popular fruit grown in Malaysia. It is well known for the rich nutrient contents, and it is commercially available worldwide. It is rich in anthocyanins and antioxidants. Dragon fruit is also an essential source of betacyanin, which serves as a red/purple pigment with antioxidative properties. The objective of the present work is to study the stability of natural colorant from dragon fruit peel. The crushed peel and water were taken in the ratio of 1:10 and was subjected to seven different types of extraction techniques such as microwave-assisted extraction, ohmic heating, ultrahigh-pressure homogenization, sonicator, supercritical fluid extraction, aqueous extraction, Soxhlet extraction. Out of the microwave-assisted extraction had the most Anthocyanin content, and it was used for further studies. The selected extract was filtered, and the stability of anthocyanin was examined at varying pH (2…10) and temperature (60…100⁰C). In addition to this, thermal stability (80…100 ⁰C for 150 min) was checked at a deferent time interval (80 to 100⁰C…150 min.). The microwave extract was used for the encapsulation process using maltodextrin, and soy protein isolate as carrier material with 1:4, 1:5 core to wall ratio by spray drying and freeze-drying techniques. The quality analysis, such as total anthocyanin content, encapsulation efficiency, color, water activity, bulk density, solubility, and moisture content, were analyzed of microencapsulated anthocyanin extract. This result showed that encapsulated dragon fruit peel (pitaya) powder could be used as a natural colorant in food applications.

Aging is a natural process in human life and is triggered by the presence of free radicals (ROS). The use of antioxidants from natural ingredients is one of the breakthroughs to overcome aging and counteract the harmful effects caused by the free radicals. This study aimed to determine and compare the antioxidant activity of H2O2 scavenging and hyaluronidase inhibition of red dragon fruit peel extract (DFPE) and kaempferol-3-o-rutinoside (KOR) compounds. Dragon fruit peel extract (DFPE) is obtained through extraction by maceration method using 70% ethanol solvent. The design of this study included antioxidant and anti-aging activity assay of EKBN and KOR at the series concentration of 15.63; 31.25; 62.50; 125; 250; 500 µg/mL through H2O2 scavenging, as well as the DFPE and KOR hyaluronidase inhibition assay at the series concentration of 5.21; 10.42; 20.83; 41.7; 83.33; 166.67 µg/mL. EKBN shows that the average activity of H2O2 scavenging is lower than KOR. In addition, the IC50 values of KOR for H2O2 scavenging is lower (351.46±2.30ug/mL) than DFPE (409.64±23.17ug/mL). While, KOR also has higher values of inhibitory activity than of the DFPE. However, the IC50 value of KOR for hyaluronidase inhibition activity was 84.07±10.46µg/mL, equivalent to the IC50 value of DFPE (85.32±10.24µg/mL). The presence of antioxidant and anti-aging activity in the EKBN is probably caused by betalain and the KOR compound itself contained in red dragon fruit. The results of the paired-samples T-test on antioxidant activity and anti-aging of DFPE and KOR showed non-significant difference. Thus, DFPE has an equivalent antioxidant and anti-aging through H2O2 scavenging and hyaluronidase activity as possessed by the KOR compound.
