What are the advantages of using supercritical extraction technique to extract sesame oil?

 Supercritical extraction is a technique that uses supercritical fluids, such as carbon dioxide, as solvents to extract desired compounds from a variety of materials, including plant matter. This technique has several advantages over traditional extraction methods, such as steam distillation and solvent extraction.

Firstly, supercritical extraction is a more efficient method of extracting desired compounds from materials. Supercritical fluids have unique properties that make them better solvents than traditional solvents. Supercritical fluids have high diffusivity, low viscosity, and high density, which allows them to penetrate materials more deeply and extract more compounds than traditional solvents.

Secondly, supercritical extraction is a more environmentally friendly method of extraction. Unlike traditional solvents, supercritical fluids are non-toxic, non-flammable, and do not leave any harmful residues behind. This makes them safer for both the environment and the workers who handle them.

Thirdly, supercritical extraction allows for more precise control over the extraction process. The temperature and pressure of the supercritical fluid can be adjusted to optimize the extraction of specific compounds. This allows for a more targeted and efficient extraction process, resulting in higher yields of desired compounds.

Finally, supercritical extraction can produce a higher quality extract. Traditional extraction methods can damage the delicate chemical structures of the compounds being extracted, resulting in a lower quality extract. Supercritical extraction, on the other hand, is a gentle extraction method that minimizes damage to the compounds being extracted, resulting in a higher quality extract.

Overall, the use of supercritical extraction technique to extract sesame oil offers several advantages over traditional extraction methods, including increased efficiency, environmental friendliness, precise control, and higher quality extract.
