Abstract Dragon fruit (Hylocereus polyrhizus) peel is high in antioxidants and fiber; however, it is discarded during processing. In this study, changes in physico-chemical properties of dragon fruit peel after drum drying were determined. Ground dragon fruit peel was drum dried at 1 rpm with 2 bar steam pressure, then analyzed for physical, chemical and functional properties. The betacyanin content was twofold higher in drum-dried powder (41.55 mg/g dm) than in a fresh sample (80.21 mg/g dm), yet up to 98.62% of the total phenolic content was retained with a 3.328 mg trolox/g dm reduction in the radical scavenging activity. The density of the powder was 0.1315 g/mL with 51.44% soluble in water. The functional properties determined included water holding capacity (2.523 g water/g sample), oil holding capacity (3.565 g oil/g sample) and swelling capacity (6.233 mL/g). The results of this study indicate that drum-dried dragon fruit peel can be considered to contain potentially functional ingredients.

Anthocyanins present in the red dragon fruit peel (Hylocereus polyrhizus) can be used as natural dyes. An extraction procedure can be used to acquire anthocyanins. The maceration method was used to isolate anthocyanin dyes in this analysis. The aim of this study was to see how the solvent ratio affected the total anthocyanin content in the skin of red dragon fruit. This research used laboratory experimental method using descriptive analysis. The solvent ratios used were (1:30, 1:40, 1:50 and 1:60) with a mixture of distilled water with 10% citric acid as the solvent. Parameters observed were total yield, pH, residual solvent content, spesific gravity and total anthocyanin content.  The best treatment was found to be red dragon fruit peel with a solvent ratio of 1:30, which produced the highest total anthocyanin content of 4.73 mg/L. This treatment resulted total yield 7.40%, residual solvent content 0.05%, spesific gravity 1.30, and pH 1.05, respectively.  It was proven that the more solvent added could linearly decrease the effectiveness of anthocyanin extraction of dragon fruit peel extracts.

Hylocereus Polyrhizus

Dragon fruit (Hylocereus polyrhizus) has polyphenols as an antioxidant. It has known that the antioxidant content of dragon fruit peels was more than in the flesh, so it can be used as a source of natural antioxidants to replace synthetic antioxidants. The use of dragon fruit (Hylocereus polyrhizus) peel, especially as topical preparations in the form of body butter, was still rarely done, whereas dragon fruit peel as an antioxidant can be used as an active ingredient of cosmetics. The purpose of this study was to obtain the body butter formula of ethanol extract of dragon fruit (Hylocereus polyrhizus) peel and its physical quality evaluation, to know the antioxidant activity of ethanol extract of dragon fruit (Hylocereus polyrhizus) peel and its body butter. This research was an experimental study with the stages of research consisting of determination of native plants, making ethanol extract of dragon fruit (Hylocereus polyrhizus) peel, ensuring its activity antioxidant, performing body butter formulation procedures, carrying out physical quality evaluation such as organoleptic, homogeneity, pH, spread, protection, and adhesion ability, then antioxidant activity of its body butter. The result of this research showed that the ethanol extract of dragon fruit (Hylocereus polyrhizus) peel has a moderate level of antioxidant (Antioxidant Activity Index / AAI = 0,88). Furthermore, body butter which has contains antioxidant content of ethanol extract of dragon fruit (Hylocereus polyrhizus) peel as much as 0.5% has the best physical quality evaluation during storage and the highest AAI (0,54) among other body butter formulas.

This research aimed to find out effect of the dipping water temperature on characteristics of  herbal tea drink from red dragon fruit peel. This study used the completely random design of treatment with dipping temperature treatment 50oC, 60oC, 70oC, 80oC, 90oC and 100oC. The treatment was repeated in 3 replications, resulting in 18 experimental units. Data were analyzed by variance analysis and continued with Duncan's test. The results showed that the dipping temperature of herbal tea drink from red dragon fruit peel affected the total phenol, antioxidant activity, color taste and overall appearance. The best treatment was obtained with temperature of 100oC which produced herbal tea drinks with antioxidant activity (IC50) which was 8.50 mg/ml, juice content 1.94%, total phenol 0.83 g/100g, and sensory characteristics of color was very red color and liked, ordinary aroma, taste liked and overall acceptance liked.
