Optimal extraction method for Lycopene containing oil for the application in food and cosmetic products by CO2 extraction

Process for the extraction by means of supercritical CO2:
A process has been worked out for the production of lycopene containing tomato seed oil by extracting 600 g batches of dried milled intermediate residue or final residue of a tomato processing plant.
20% Ethanol is used as co-solvent
Extraction conditions: P= 296 bar T= 80°C
Precipitation conditions: P= 50 bar T= 35 °C

The yield in tomato seed oil is, raw material depending, 3-6%. The Lycopene yield is, also raw material depending, 15 - 180 ppm

The extract is separated by centrifugation in order to obtain the Lycopene containing oil in the lowest fraction.

The oil is sensitive to oxidation which can be prevented by the addition of 0,1% Vitamin E.
