Q.57
Which of the following method uses an ideal solvent Carbon dioxide (CO) for extracting essential oils from flower crops?
- Supercritical Fluid Extraction (SFE):
- An advanced extraction technology utilizing Carbon Dioxide ($CO_2$) in its supercritical fluid state (above critical temperature $31.1^\circ\text{C}$ and critical pressure $73.8\text{ bar}$).
- Supercritical $CO_2$ behaves as a non-polar, non-toxic, non-flammable solvent that penetrates floral tissues to extract volatile essential oils without thermal degradation or toxic organic solvent residues.
- Correct Option: Option 3 (Supercritical Fluid Extraction).
