A Review on Supercritical Fluid Extraction (SFE) of Lycopene From Tomato and Tomato Products

Safety assessment of a natural tomato oleoresin containing high amounts of Z‐isomers of lycopene prepared with supercritical carbon dioxide

“…Tomato oleoresin was extracted with supercritical carbon dioxide from pulverized dry tomato pulp (approximately 3 g kg −1 lycopene content, less than 100 g kg −1 moisture content, less than 1.5 mm particle size), as described previously . Extraction was conducted under the conditions: extraction temperature, 80 °C; pressure, 45 MPa; flow rate, 600 kg CO 2 h −1 ; dynamic extraction time, approximately 2 h per batch; mass of the dry tomato pulp, approximately 50 kg per batch).…”

“…In the present study, we evaluated tomato oleoresin that contained 10.9% lycopene with 66.3% Z ‐isomer and had been extracted with supercritical carbon dioxide. Supercritical fluid extraction has been used extensively to extract essential oils, wax and bioactive compounds containing lycopene from food products. It is considered to be a safe method because it leaves no residual solvent and carbon dioxide has low toxicity .…”

Optimizing the supercritical fluid extraction process of bioactive compounds from processed tomato skin by-products

“…On the case of extraction with supercritical CD 2 , temperature appears to be one of the most important parameters for yielding the target compound. On the specific case of lycopene extraction, different research studies indicate temperature as a parameter of fundamental importance in order to increase the yield of the extract (Reverchon & De Marco, 2006;Egydio et al, 2010;Konar et al, 2012;Yi et al, 2009). At the temperature of 80 °C, lycopene solubility in supercritical CD 2 showed a decrease, probably due to its thermal degradation.…”

Supercritical Fluid Extraction of Carotenoids

“…In a study conducted on the supercritical CO 2 extraction of trans-lycopene, Nobre et al (Konar et al 2012) utilized fresh tomato industrial waste which was composed of a mixture of skins and seeds with an initial moisture content of 82.9 %. The tomato industrial waste was then dried to moisture contents of (58.1, 22.8, 4.6) %, respectively.…”

“…According to Konar et al (2012), in SFE, extraction under low pressure and temperature conditions can inhibit trans-cis isomerization but the products should be protected against heat and oxygen. Solubility increase depends on both pressure and temperature and it has a significant effect on extraction efficiency.…”
