Se llevó a cabo la extracción y asilamiento de inulina, a partir de tubérculos de Dalia imperialis Rotez (Asteraceae), obteniéndose un rendimiento de 13.7% en base seca. El producto obtenido fue identificado mediante métodos físicos, químicos, cromatográficos y espectroscópicos; su caracterización fue realizada de acuerdo con los patrones de la Farmacopea de los Estados Unidos (USP 23). Algunos ensayos fueron realizados con el fin determinar la utilidad de la inulina como prebiótico en los alimentos, en la elaboración de leches fermentadas con bifidobacteria, especialmente Bifidum infantis. En estos ensayos se observó que la inulina estimula y promueve el crecimiento de esta bacteria.
The extraction and isolation of inulin was accomplished, from the tubers of Dahlia imperialis Roetz. (Asteraceae), obtaining a yield of 13.7% a dry base. The obtained product was identified by means of physical, chemical, chromatographic and spectroscopic methods; its characterization was made according to the patterns of the United States American Pharmacopeia (USP 23). Some were made assays to determine the practical and functional profits of inulin, such as its use as prebiotic food, in the manufacture of fermented milks, with bifidobacteria, specifically Bifidum infantis. In these assays, it was observed that inulin stimulates and promotes the growth of these bacteria.
