Abstract: This work described the influence of some operative parameters of supercritical carbon dioxide extraction employed for the separation of lycopene and β-carotene,lutein from the pulp and skins of ripe tomatoes.The extractions were conducted at pressures and temperatures ranging from 10 to 45 MPa and 40 ℃ to 80 ℃,respectively.Lycopene and β-carotene,lutein showed a different solubility in the supercritical fluid depending on processing parameters.With a proper choice of operative parameters,it has been possible to obtain a product that contained 80.25% lycopene.Therefore,purification processing can be avoided.
