Extracción de antioxidantes a partir de subproductos del procesado de la almendra - Garrido, Ignacio; Monagas Juan, María Josefina; Gómez-Cordovés de la Vega, María del Carmen; Bartolomé Sualdea, Begoña
In this work, 8 different solvents/mixtures have been tested for the extraction of antioxidants from by-products derived from the industrial processing of almonds (skin or seed coating, brown hull, and green shell cover or mesocarp). The oxygen radical absorption capacity (ORAC) as well as the phenolics content of the extracts has been determined. The extracting solution methanol/HCl (1000:1, v/v) was the
most effective for the almond skin and shell, whereas, for the hull, it corresponded to acetone/water (50:50, v/v), resulting in ORAC-Fluorescein values of 0.467, 1.45 and 0.0504 mmol of Trolox/mg, respectively. At the same time, the mixtures
acetone/water exhibited the highest...
