Dragon fruit skin, waste material (dragon fruit waste), will have a profitable sale value if it can be used as a food raw material. Dragon fruit skin waste contains relatively high dietary fiber so it can be used as a food raw material. This study aims to utilize dragon fruit skin waste for the manufacture of dragon fruit skin flour as an alternative food source. Some tests are made on white-meat dragon fruit skin, red-meat dragon fruit skin and super red dragon fruit skin. The preliminary study is the soaking of the three types of dragon fruit skin in two solutions, namely 0.1% sodium citrate and 0.1% sodium metabisulfite to prevent the browning effect on flour. Dragon fruit skin flour from the soaking with both solutions is then characterized physically, including its texture, color, flavor and rendement. The best physical characterization is followed by chemical characterization, including the contents of water, ash, protein, fat, carbohydrate, dietary fiber, minerals (Fe, Na, K, Ca and P), and also microbiological characterization of Escherichia coli, molds and Bacillus cereus. The chemical and microbiological characterization shows that the red-meat dragon fruit skin flour has better results than the white-meat and super red dragon fruit skin flour does. The red-meat dragon fruit skin flour contains 8.80% water, 0.20% ash, 2.35% fat, 7.69%, protein, 68,29% carbohydrate and 28,72% dietary fiber as well as 4.40 mg K, 8.76 mg Na , 0.65 mg Fe , 10.20 mg Ca and 32.58 mg P. Keywords: Waste, Dragon Fruit Skin, Dragon Fruit Skin Powder, Alternative Food Source

This study aims to produce natural pigments for food prepared from dragon fruit skin by extraction and freeze-drying and to assess the effect of additional ethanol as extraction solvent on the process yield. During extraction stage, the effect of solvent (pure water and additional ethanol) on the yield of bioactive materials was assessed. Furthermore, during freeze-drying, the effect of maltodextrin addition as carrier agent on the quality of powder has also been evaluated. It has been found that the addition of ethanol as extraction co-solvent may give a positive effect on the yield of bioactive materials in the dragon fruit skin extracts, including the contents of anthocyanin, betacyanin, and total phenolic compounds. Regarding freeze drying, it was found that high recoveries of bioactive materials (84-92%) had been achieved, which indicates that freeze-drying may be suitable for drying such heat-sensitive materials. In addition, it was found that the addition of 10% maltodextrin as carrier agent may decrease the moisture content of the powder significantly, up to 8.162.12%, which is beneficial for its storage stability.Keywords: betacyanin; food additives; dragon fruit; extraction; anthocyanin.

Yoghurt is a fermented milk product that can provide beneficial effects to the health of consumers. Increasing the quality of yoghurt can be made by combining the benefits of probiotic with prebiotic to produce sinbiotic yoghurt. Inulin is a prebiotic that found in many dahlia tuber (Dahlia variabilis Willd.). Pure inulin were expensive, so the alternative is using dahlia tuber flours filtrate as prebiotic ingredients. This study aimed to examine the addition of Dahlia Tuber Flours Filtrate (DTFF) as a prebiotic in sinbiotic yoghurt making using Lactic Acid Bacteria (LAB) Lactobacillus bulgaricus, Streptococcus termophilus dan Lactobacillus acidopilus as probiotic. This research using Completely Randomized Design (CRD) with 4 concentration treatments DTFF 0%, 3%, 6% and 9% with 3 replications. Observed variables consist of the number of total LAB, lactic acid level, pH and organoleptic attributes (aroma, flavor, consistency and impression). Data the number of total LAB, lactic acid level and pH values ​​were analyzed by ANOVA, continued by Duncan test, while the organoleptic data was analyzed by Mann-Whitney U test with 95% significant level. The results showed that the addition of DTFF significantly affect the increasing of total LAB, lactic acid level, organoleptic assessment and decreasing pH of sinbiotic yoghurt. Sinbiotic yoghurt with 3% of DTFF concentration is most preferred by panelists and required the criteria of Indonesian National Standard (SNI) for yoghurt with enough likely aroma, sour taste/specify and enough thick texture with total LAB 2,4 x 108 CFU/ml, 1.3% lactic acid levels and 4.2. pH.
