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.

Rhodamin B

Introduction: Food circulation among communities is prone to chemical contamination. The contamination is obtained from both food processing and food cultivation (planting, raw materials). One of the examples related to chemical contamination can be seen in the contamination of rhodamine B on Terasi. Although there is a prohibition on using Rhodamine B compounds in food add-ons, which is listed in Regulation of Ministry of Health of Republic Indonesia No.722/Menkes/Per/IX/1988, its usage is widely found. Similarly, chlorpyrifos pesticide residue in lalapan is the other example provided. The usage of it remains to continue even though the result of pesticide residue value is under BMR SNI 7313:2008. The article aims to study food processing efforts in minimizing the chemical contamination of Rhodamine B in shrimp terasi and chlorpyrifos residue in the lalapan vegetables in the communities in Indonesia. A literature review on scientific publications was undertaken through Google Scholar, ResearchGate, Neliti, ScienceDirect, LIPI, Directory Open Acces Journal, and Crossref. The keywords used were related to rhodamin B on terasi, synthetic dyes on terasi, natural dyes for terasi, vegetable pesticide residues, Chlorpyrifos residue on vegetables, and how to reduce chlorpyrifos residue in vegetables. All of them were published between the 2015 – 2020 period. Discussion: Chlorpyrifos residue in vegetables can be reduced by washing, soaking brine, and boiling. The usage of rhodamine B on Terasi can be replaced by the application of dragon fruit skin extract and angkak (red yeast rice) for natural dye alternatives. Conclusion: Washing food with running water and soaking it in hot water before food consumption can lower chlorpyrifos residue level in dark vegetables. However, it is more significant to lover the residue level through the boiling step. The use of natural pesticides can be used as the choice of alternative. Moreover, rhodamine B on terasi can be replaced with natural dye alternatives such as angkak (red yeast rice) and dragon fruit skin extract.
