Bixa orellana seeds (Annatto) have been used in food coloring and cosmetics. The main commercial processes to extract the pigment from annatto seeds were direct extraction into oil or aqueous alkali and indirect extraction using organic solvents. This research was held to determine the color and physicochemical properties of annatto extracts using aqua dest as a solvent. The extraction was carried out by maceration at various pH of aqua dest (4, 7, and 9) at 80oC for 10 minutes. Color property of brightness (L), redness (a), and yellowness (b) was determined using a color reader. Physicochemical characterization was conducted by observing pH value, total titrated acid, total dissolved solids, and total solids. The results showed that the color and physicochemical properties of annatto extract were influenced by the pH of aqua dest influences. The highest brightness (43.8), redness (9.37), yellowness (42.5), and total soluble solid (1.67o Brix) was produced by extraction using pH 7 of aqua dest, while the highest of total titrated acid (4.2%) of extract produced in pH 4. The lowest pH of the extract (4.83) was resulted in extraction using aqua dest pH 4. The higher the pH of the solvent, the higher the pH of the extract. The different pH of aqua dest used to extract annatto seeds resulted in various color intensities and physicochemical property. [ABSTRACT FROM AUTHOR] |
