CHEMICAL-COMPOSITION OF EXTRACTED DRIED OLIVE POMACES CONTAINING 2 AND 3 PHASES

The chemical composition of extracted dried olive pomaces, obtained fr om extraction of systems containing two and three phases, was similar. The main component was fibre, with values above 70% in both systems. Nitrogen values and extractability was low for both systems, although in vitro protein digestibility was high (75-80%). Amino acid compositi on was balanced except for ly-sine. The isoelectric point was low, cen tred around pH 2.0. Soluble sugars and organic acids contents were sim ilar as well as fatty acid composition of the extracted oil from olive pomace. Therefore, an oil extraction of a system of two phases is adv isable as environmental problems could be reduced with the elimination of vegetation water, and similar applications could be carried out wi th both types after drying.
