increasing solubility of lycopene and higher lycopene recovery.
Moreover, increasing temperatures enabled better transport of solute
in the matrix and/or from the matrix to the solvent, presumably
due to damage to the particles (Vasapollo et al., 2004) and
the partial destruction of the vegetable structures that contain
lycopene. Difficulties remain in investigating temperature effects
on the extraction process. In fact, solvent density decreased with
increasing temperature at a constant pressure, resulting in reducing
solubility of lycopene, but the magnitude of density change is
smaller than that of solute vapor pressure at higher pressures. In
the case of tomato seed oil extraction, the increasing temperature
had no significant effect on seed oil recovery. Under these conditions,
both density and oil vapor pressure change controlled the
extraction process.
