A találmány likopinforrás érintkeztetésére vonatkozik szuperkritikusfolyadékkal olyan körülmények között, amelyek lehetővé teszik alikopin feloldását ebben a szuperkritikus folyadékban, valamint alikopinkoncentrátum elkülönítését a likopint tartalmazó szuperkritikusfolyadék nyomásának csökkentésével. Ha a nyomáscsökkentést 10 MPaalatti nyomásokon hajtják végre, oleorezint kapnak, és ha anyomáscsökkentést ezen érték feletti nyomásokon hajtják végre,kivonatot nyernek, amelyek mindegyike likopinban dús és szervesoldószerektől mentes. A koncentrátum és a megfelelő készítményekantioxidáns tulajdonságokkal rendelkeznek, és felhasználhatókélelmiszerek, kozmetikumok, valamint gyógyszer- és élelmiszer-iparitermékek kidolgozására. Ó The procedure concerns placing into contact a lycopene source with a supercritical fluid under conditions that permit the solubilisation of lycopene in this supercritical fluid and to separate the lycopene concentrate by depressurisation of the supercritical fluid loaded with lycopene. When the depressurisation is carried out at pressures below 10 MPa, an oleoresin is obtained and when it is performed at pressures above this an extract is obtained, both of which are rich in lycopene free of organic solvents. The concentrate and the compositions it comprises have antioxidant properties and are useful for elaborating food products, cosmetics and pharmaceutical and nutraceutical products.
