Abstract
Processing destoned olives by means of extracting adjuvants micronised food talc and depolymerising Cytolase 0 enzyme complex have been studied in the present work This innovative processing technology increased the plant efficiency amounts of olives processed per hour by 20 as well as the nutritional quality of the end product with respect to functional compounds The oils showed higher contents of biophenols aromas and tocopherols An intense and balanced flavor and a potentially higher stability and endurance to oxidation shelflife was found Contents of chloroplast pigments chlorophylls pheophytins carotenes and xanthophylls appeared to be lower in comparison to conventional processing The processing aids allowed to increase significantly the oil yields and to reduce the oil percentage in the byproducts Traceability of the new products was still possible applying chemometric data analysis for discriminating between cultivarsThis work was part of the special projects “Valorolio” and “Riom” funded by Ministero delle Politiche Agricole Alimentari e Forestali MiPAAF Rome Italy Concerning the latter project CIPE gave funds to MiPAAF This is also thanked for a fellowship to both Marchegiani D and Girardi F
