Resumen

BEAS F., Rosalba et al. Nutraceutic potential of bioactive components present in huitlacoche from the central zone of Mexico. Rev. mex. cienc. farm [online]. 2011, vol.42, n.2, pp.36-44. ISSN 1870-0195.

Huitlacoche is a mushroom consumed traditionally in Mexico and is currently considered a food alternative. Proximate analysis, carbohydrates and phenolic compounds, as well as antioxidant activity were analyzed in huitlacoche samples. Considerable levels of protein [11.5-14.2 % dry basis (db)] and 54 to 65 % db of total dietary fiber (official enzymatic-gravimetric method) were found. High performance liquid chromatography (HPLC) analyses detected high levels of the oligosaccharides raffinose, stachyose and verbascose (1505, 541 and 2611 mg/100 g db, respectively). HPLC also detected ferulic, 4-hydroxibenzoic, syringic and protocatechuic acids, mainly. Methanol extracts of huitlacoche showed high antioxidant activity (57-74 % anti-radical activity, 2,2 diphenyl-1-picrylhydrazyl method). Considerable quantities of dietary fiber, oligosaccharides, phenolic acids and high antioxidant activity give huitlacoche a value as a functional food with nutraceutic potential.
