Extracción y microencapsulación de carotenoides con actividad antioxidante a partir de Daucus carota
(Universidad Técnica de Ambato. Facultad de Ciencia e Ingeniería en Alimentos y Biotecnología. Carrera de Ingeniería Bioquímica, 2019-07) Fiallos Yánez, Henry Alexis; López Hernández, Orestes Darío
The present research work was based on the extraction and analysis of metabolites of the Daucus carota plant for its antioxidant properties, taking as a starting point the extraction of carotenoids based on an experimental surface design. To take advantage of the properties of the extracted metabolites, microencapsulated microcapsules containing the antioxidants of the extract of the Daucus carota plant were developed, using two saccharide-type polymers which were maltodextrin and gum arabic of great commercial use with which a microencapsulation efficiency of 92.21 percent was obtained, which were used to verify the antioxidant properties by means of in vitro tests by the DPPH method to analyze the percentage of inhibition of free radicals in which 394,076 μmol equivalents of Trolox was obtained. A percentage of inhibition of 71.20 percent for the microencapsulation, and in the antioxidant activity in vivo through the growth curve of the yeast Saccharomyces cerevisiae the antioxidant potential was determined.
