This study aimed to compare the extraction methods Anthony drugs tribe of purple corn. By solvent extraction in two types of ethanol hydrochloric acid. And extracted with
ethanol concentrations by 48 percent, both at the temperature of 50 ° C for 45 minutes study of substance Anthony Saiyan extracted from purple corn cob husks and silk. And study the dynamics of the film indicates that affect the quality monitoring of food products. The study found that The solvent ethanol concentration to 48 percent by Anthony drugs tribe of purple corn was the highest was 19.86 milligrams per liter. The acidity (pH) of 5.88 Color L * a * b * Chroma and Hue angle was 37.55 ± 0.18, 21.87 ± 0.08, 30.92 ± 0.45, 0.96 ± 0.01 and 37.88 ± 0.35, respectively, by volume Anthony. Zrenjanin extracted from silk purple corn with solvent ethanol concentration of 48 percent can be extracted Anthony, Zrenjanin was the highest, followed by the shell and corn cob purple equals 375.23 74.51 and 19.86. milligrams per liter, respectively, the acidity (pH) of the substance Anthony Saiyan extracted from silk purple corn was 5.56 color L * a * b * Chroma and hue angle was 7.11 ± 0.08, 21.19 ±. 0.12, 5.71 ± 0.37, 21.95 ± 0.19 and 0.26 ± 0.02, respectively, brought Anthony Saiyan extracted from silk purple corn with solvent ethanol concentration, 48 percent is used to produce sheets. the film indicates deterioration The application indicates the film with rice dessert products. Keep at room temperature, the color values L * a * and b * of the film indicates an upward trend, as the shelf life of rice cakes for the duration of 28 hours.
