PROCESS FOR THE ISOLATION AND PURIFICATION OF LYCOPENE CRYSTALS

摘要

A process for isolating and purifying lycopene crystals from a biological lycopene source is disclosed. A lycopene-containing oleoresin is saponified in a composition of propylene glycol and aqueous alkali to form lycopene crystals. Crystallization is achieved without the use of added organic solvents. The crystals are isolated and purified. The substantially pure lycopene crystals so obtained are suitable for human consumption and can be used as a nutritional supplement and as an additive in food.
