The Effect of Technical Parameters on Lycopene Extraction in Supercritical Fluid Extraction From Freeze-Dried Tomato Pomace (Peels and Seeds)

Abstract:

Supercritical fluid extraction (SFE) of lycopene from freeze-dried tomato pomace(peels and seeds) with CO₂ was explored. The effect of different technical parameters, such as temperature (40°C, 50°C, 60°C), pressure (35MPa, 40MPa, 45MPa) and particle size (three degree index), on the extraction yield and the content of lycopene in extracts was determined with statistical analysis.The product obtained by supercritical CO₂ extraction at over 35MPa contained the highest concentration of lycopene, while the product rich in β-carotene and lutein was obtained at below 30MPa.The product obtained by supercritical CO₂ extraction at 40MPa and 60°C contains the highest concentration lycopene of 32.52±1.02g/100g dry material.
