Resumen:
he objective of this work was to deepen on the study of functional properties of the phytochemicals present inProsopis alba exudate gum (G), as well as to rule out possible adverse effects of some of its components.Commonly employed purification methods were compared. Filtration prevents further loss of potentiallybioactive compounds. The filtrated gum showed a higher concentration of phenolics, flavonoids and tanninsthan arabic gum, which was correlated with better in vitro antioxidant properties. Particularly, tannins, commonlyconsidered as toxic compounds in exudate gums, were found in lower concentration than in others gumsobtained from genus Prosopis and Acacia. The toxicological evaluation performed on rats did not show symptomsof intoxication associated with the administration of the gum. These results provide useful evidence to supportthe potential use of G as a safe functional food additive with the added benefit of taking advantage of a nonexploitednatural resource.
