Lycopene recovery slightly increased with increasing temperature. The increasing temperature caused an increasing in vapor pressure of the lycopene, resulting in 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.
