Abstract

The aim of this research is to knowing about the stability of anthocyanin dye against the influence of pH and temperature, and also degradation of color from purple sweet potato’s peel extracts. The process of sweet potato extraction was done by maceration using ethanol 96%. Anthocyanin stability test was performed on the pH, and variation of pH are 1, 3, 5, 7 and 9. While, temperature variation that used are room temperature, 40°C, 60°C, 80°C and 100°C. To know the absorbance value for color degradation of anthocyanin was measured using a UV-Vis spectrophotometer at 528 nm wavelength maximum. The results of analysis data statistic by using (ANOVA) two way advanced to Duncan test (SPSS 17.0) in stability of pH and temperature are showed that samples more stabile at pH 1 than pH 3 and 5 because there are significant value. The result of % color degradation from pH sample 1, 3 and 5 respectively are 1,47% ; 49,63% and 52,32%.

Abstract

Telah dilakukan penelitian pembuatan Nata dari kulit pisang raja (Musa paradisiaca L) dengan memvariasikan kadar sukrosa dan pH dalam proses pembuatannya, bakteri Acetobacter xylinum digunakan digunakan untuk proses fermentasi. Variasi sukrosa yang digunakan yaitu ; 25 gram, 30 gram, dan 35 gram. Variasi pH yang digunakan yaitu : pH 3, 4, dan 5. Hasil Nata memperlihatkan bahwa nata terbaik didapatkan pada penambahan sukrosa 35 gram dan pH 4.
