Study of a Process for the Extraction of a Betacyanin-Based Nature Colouring from Viet Nam Red Dragon
Main Article Content
Abstract
Dragon fruit has gradually become one of the most popular fruits of the Vietnamese. Dragon fruit is not only a nutritiou fruit, it is also a source of betacyanin pigments used in foods, pharmaceuticals and Dye-sensitized solar cell (DSSC). In this study, batacyanin was extracted from the pulp of the red dragon fruit with the aid of ultrasound. Extraction results were analyzed using UV-Vis absorption spectrometry method. Results showed that the optimal technical conditions for for the extraction are: solvent is, a mixture of distilled water and absolute alcohol with ratio H₂O: C₂H₅OH = 1: 1; temperature T = 40℃; sample mass m = 12.5 g; extracting time t = 40 mins. Concentration of betacyanin was about 334 mg/l.
