Extraction of oils from wheat germ with supercritical carbon dioxide.

Supercritical CO2 extraction of fatty oil from flaxseed and comparison with screw press expression and solvent extraction processes

“…The yield of oil in soxhlet extraction process was in agreement with the value reported by Bhatty (1997). Whereas, the polar lipids were less soluble in supercritical CO 2 (Taniguchi et al, 1985), therefore supercritical CO 2 at the above mentioned conditions was selectively extracted the desired fatty acids such as neutral lipids.…”

“…Furthermore, the low critical temperature of CO 2 (31°C) allows extraction of thermolabile compounds without degradation (Rizvi, 1994). A number of other plant oils including sunflower, rapeseed (Stahl et al, 1980), corn (Friedrich and Pryde, 1984), wheat germ (Taniguchi et al, 1985), palm (Kalra et al, 1987), canola (Fattori et al, 1988), cottonseed (Bhattacharjee et al, 2007), safflower seed (Han et al, 2009) were also successfully extracted with supercritical CO 2 . Reverchon and De Marco (2006) reviewed, the numerous works carried on the application of supercritical CO 2 in food processing, pharmaceuticals and nutraceutical.…”

Supercritical carbon dioxide extraction of cottonseed oil

“…A lot of work published on SFE in the food processing industry has dealt with extraction of vegetable oils (Bulley, Fattori, Meisen, & Moyls, 1984;Christianson et al, 1984;Dakovic, Turkulov, & Dimic, 1989;Hierro & Santa-Maria, 1992;Lee, Bulley, Fattori, & Meisen, 1986;List, Friedrich, & Pominski, 1984;Stahl, Schü ltz, & Mangold, 1980;Taniguchi, Tsuji, Shibata, & Kobayashi, 1985). Supercritical carbon dioxide (SC-CO 2 ) has been established as a good alternative solvent for several lipid processing operations such as separation of FFA from vegetable oils, separation of polyunsaturated fatty acids (PUFA) from animal lipids, refining and deodorization of vegetable oil, fractionation of glycerides, recovery of oil from oil bearing materials, deoiling of lecithin and decholesterolization and delipidation of food products (Mukhopadhyay, 2000).…”

Experiments and Numerical Simulations of Supercritical Fluid Extraction for Hippophae rhamnoides L Seed Oil Based on Artificial Neural Networks

“…2 In the SCFE field, seed oil extraction from various types of plants has been studied and many factors influencing the extraction rate have been investigated. [3][4][5][6][7][8][9][10] Recently, much attention has been given to modeling the SCFE processes of natural products from a variety of plants. Several models have been proposed to describe the extraction rate using the mass transfer coefficient in either the solvent phase or the solid phase.…”
