A liquid phase rich in bioactive compounds, such as phenols and sugars, is obtained from olive oil waste by novel thermal treatment. Two groups of fractions with common characteristics were obtained and studied after thermal treatment, acid hydrolysis, separation by ultrafiltration and chromatography and finally by Superdex Peptide HR. In the first group, which eluted at the same time as oligosaccharides with a low DP, an oleosidic secoiridoid structure conjugated to a phenolic compound (hydroxytyrosol) was identified as oleuropeinic acid, and three possible structures were detected. In the second fraction, glucosyl structures formed by hydroxytyrosol and one, two or three units of glucose, or tyrosol and glucose have been proposed. Verbascoside, a heterosidic ester of caffeic acid, in which hydroxytyrosol is linked to rhamnose-glucose, or one of its isomers was also identified. Neutral oligosaccharides bound to a phenol-containing compound could be antioxidant soluble fibers with bioactive properties.
