Grape seed has a well-known potential for production of oil as a byproduct of winemaking and is currently produced as a specialty oil byproduct of wine manufacture. Seed oils from eight varieties of grapes crushed for wine production in British Columbia were extracted by supercritical carbon dioxide (SCE) and petroleum ether (PE). Oil yields by SCE ranged from 5.85 卤 0.33 to 13.6 卤 0.46% (w ...

Highlights Grape seeds oils was obtained by supercritical extraction in laboratory and pilot plant scale. The scale-up criterion of constant ratio of solvent to feed mass was successful. Economic evaluation of the process was performed using a commercial software. The best relationship between cost and oil yield was for process conditions of 313 K, 35 MPa, 240 min and S/F of 6.6.

Supercritical fluid extraction (SFE) of vegetable oils is an alternative method to organic solvent (namely hexane) and mechanical extraction. To exploit the SFE technology at industrial scale, the process has to be optimized. An effective way to perform optimization is to resort to models that are capable to describe and simulate the SFE process.
