Obtención de un extracto rico en polifenoles a partir del residuo de la pulpa de mortiño (Vaccinium meridionale)

Abstract

The blueberry (Vaccinium meridionale) due to its hig h content of polyphenolic compounds is of great commercial interest. In the present investigation research, a liquid extract rich in polyphenols was obtained from residues of the blueberry pulp (Vaccinium meridionale) using water as solvent, the liquid extract was spray dried at an inlet temperature of 150 Celsius degrees and output temperature of 90 Celsius degrees; microencapsulated with maltodextrin, the content of anthocyanins in the dry extract was subsequently measured. The optimal parameters for obtaining the extract were residual ratio per solvent 1:10 and 45 minutes of removal extraction. The content of polyphenols in the extract was 616.44 more less 17.30 mg GAE per gram, while in the dried extract the content of anthocyanins was 122,95 more less 4.50 mg per 100 g, with a moisture content of 5.54 percent and a yield of 45.64 percent. The resulting microencapsulated serves as a functional ingredient since it contains health benefits
