Washing Water

Nata de leri is one of the products produced from fermented organic white, red, black rice washing water with the addition of red dragon fruit skin extract. In javanese the rice washing water is called Leri so that the resulting nata is called “Nata De Leri”. (carbohydrates, proteins, minerals) that are carried away from the rice membrane during the washing process. So that it can be utilized by microorganisms as a medium in making nata. The addition of red dragon fruit skin extract gives color because it contains a lot of anthocyanin and also the fiber and water content is very high. The purpose of this research was to determine the organoleptic and chemical characteristics of nata. This research used a qualitative descriptive method using a 2 factor complete randomized design and the treatment given was 75% of white, red, black rice washing water concentration, The concentration of red dragon fruit skin extract 75%, 50%, and 25%. The results showed that the most preferred texture on the addition of 75% red dragon fruit skin extract was an average of 4,65, the most preferred color in the addition of 75% and 25% red dragon fruit skin extract, the aroma of the average panelist doesn’t like all the aroma of nata de leri, for the taste all the samples were liked by the panelists because of their sweet taste. While the water content and crude fiber content produced are quite high on average but do not exceed SNI.

The Difference

Red dragon fruit skin extract is used as an antioxidant to lead acetate toxicity. This study aimed to prove the difference in morphology of mice testicular spermatozoa exposed to lead acetate. Twenty-five mice were divided into 5 groups (5 mice per group). K- group was the control group without lead acetate and dragon fruit skin extract administration, K + group was treated with 8 mg/KgBW lead acetate administration for 14 days, P1 group was treated with the administration of 8 mg/KgBW lead acetate for 14 days + 250 mg/kgBW red dragon fruit skin extract for 21 days, P2 group was treated with the administration of 8 mg/KgBW lead acetate for 14 days + 500 mg/kgBW red dragon fruit skin extract for 21 days, and group P3 was a treatment group with the administration of 8 mg/KgBW lead acetate for 14 days + 1000 mg/kgBW red dragon fruit extract for 21 days. The results showed that there was significant difference (P<0.05) in normal sperm morphology among K-, K +, P1, P2, and P3. In conclusion, the administration of red dragon skin extract at a dose of 500 mg/kgBW (P2) is the optimal one which can be used as therapy to increase motility, morphology, and concentration of mice spermatozoa exposed to lead acetate.

Ethanol Addition

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.

Dragon fruit is a kind of cactus tree from the family Cactaceae. Red dragon fruit contains lots of vitamin C, vitamin E, vitamin B1, B2, and B3. These vitamins can increase energy, and metabolize food, and even improve skin quality. This study aims to determine whether red dragon fruit skin extract can be made into lotion preparation and to know the effect of variation of red dragon fruit skin extract on physical properties of lotio. Red dragon fruit skin was extracted by maceration, lotio was made using formulation with variation of dragon fruit skin extract which were F1 (3%), F2 (5%), F3 (7%). The lotio was making by mixing the oil phase into the water. Physical test results showed there was organoleptic change in F1, F2 and F3 after observation for 4 weeks. The average result of pH test for four weeks was meet the lotio requirements ranging from 4.5-8. F1 with an average of 6.5, F2 with an average of 7.25, F3 with an average of 7.5. The result of viscosity test is F1 0,5 poise, F2, F3 and F4 0 poise. The result of F1 7.0 cm, F2 7,1 cm and F3 7.5 cm. The irritation test results are not irritating on the use of F1, F2 and F3. The test results showed that F0 and F1 are more favorable. The result of this research was that red skin dragon fruit extract can be made into lotio formulation and there was influence of variation of extract concentration on the physical properties of lotio.
