Abstract
|
|
|
|
Grape seed oil made by press or organic solvent extraction does not contain resveratrol, a bioactive compound. Supercritical carbon dioxide could extract oil containing resveratrol from grape seed. The extraction efficiency was mainly dependent on the water content in grape seed. More resveratrol was contained in the oil extracted with un-dried grape seed. No resveratrol was extracted with dried grape seed. Time course changes of grape seed oil extraction also resulted that resveratrol could be extracted by supercritical carbon dioxide with the positive influence of water.
