...) were not observed in the present work although the method was able to extract and quantify them (Chauveau-Duriot et al., 2010). This major difference between oil and OMWW reflects the lipophilic behavior of these compounds that preferably follow oily than aqueous matrices. OMWW processed with the 3-phases centrifugal system showed a significantly higher carotenoid content that was due to zeaxanthin, lutein, 13Z-b-carotene and all-E-b-carotene. This result is in agreement with the results previously observed in olive oil. Indeed, Giuffrida, Salvo, Salvo, La Pera, and Dugo (2007) reported that higher pigment contents are found in oils produced by the continuous system technology, compared to oils produced by the traditional pressure system....

...An acidic pH is a common characteristic in OMWW reported in the literature, owing to the presence of acid compounds such as phenolic acids (Chaari et al., 2015; Fakharedine, El Hajjouji, Ait Baddi, Revel, & Hafidi, 2006)....

García, Yousfi, Oliva, García-Díaz, and Pérez-Camino (2005) stated that virgin olive oils processed under stronger extraction conditions (hot water) have a significantly higher carotenoid content, probably due to the better breakage of the olive tissue and the higher paste temperature reached, that also could induce the inactivation of the enzymes responsible for pigment degradation....
