Supercritical fluid extraction process: unique and innovative extraction process
The increased public awareness of the health, environment and safety concerns
associated with the use of some organic solvents in food processing and the
possible solvent contamination of the final products. The high cost of organic
solvents and the increasingly stringent environmental regulations together with
the new requirements of the medical and food industries for ultra-pure and high
added value products have pointed out the need for the development of new and
clean technologies for the processing of food ingredients.
Supercritical fluid extraction, using carbon dioxide as a solvent, has provided an excellent alternative to the use of chemical solvents. Over the past three decades, supercritical CO2 has been used for the extraction and isolation of valuable compounds. It is non-toxic, leaves no residues, and is considered a green manufacturing process.
Supercritical fluid extraction process: unique and innovative extraction process
Supercritical fluid extraction (SCFE) process has emerged as the alternative to the traditional solvent extraction process. It is a separation technique, which is developed by use of the fluid that has the ability of dissolution at supercritical pressure and supercritical temperature.
The extraction is carried out in highpressure equipment in batch or continuous manner, the supercritical solvent is put in contact with the material from which a desirable product is to be separated. The supercritical solvent, now saturated with the extracted product, is expanded to atmospheric conditions and the solubilized product is recovered in the separation vessel permitting the recycle of the supercritical solvent for further use (Figure 1).
As the extractions are carried out at high pressures, the extraction unit is
fully automated, computerized, and highly sophisticate. Communication interfaces
and input/output modules match the most challenging requirements in industrial
automation thereby creating high degree of consistency and reproducibility
between batches/lots.
