Question
A process uses gases like CO2 at high pressure to
extract food components known as a)Â Â Â Solvent extraction b)Â Â Â Supercritical fluid extraction c)Â Â Â Steam distillation d)Â Â Â All of the aboveSolution
Supercritical fluid extraction (SFE) is a method in which supercritical fluid as an extraction medium is added to substances containing target components, and extraction is performed based on differences in solubility. Because the critical temperature of carbon dioxide is only 31 °C, extraction is possible close to room temperature. Furthermore, extraction can be carried out in a carbon dioxide atmosphere without oxygen.
