is about 0.2 g/L at room temperature (Bauernfeind et al., 1958; Borel
et al., 1996), but it clearly rises with increasing oil temperature (Ax
et al., 2003). Thus, the addition of oil as co-solvent may enhance
the recovery efficiency by increasing both the solubility of the analyte
in the supercritical fluid as well as the fluid flow rate of the lycopene
through the tomato matrix and pipeline. In addition, Lenucci
et al. (2010) reported that the presence of vegetable oil (hazelnut
oil) resulted in no degradative loss of lycopene during the extraction.
