For the Originality in Extraction

Supercritical carbon dioxide (CO2) is the most widely used fluid for the Supercritical Fluid Extraction (SCFE) process across the globe. Not only is sCO2 capable of extracting the required ingredients in their pristine form, the prime reason for the surging popularity of SCFE, it also makes the process more manageable, economical, and safe.

Increasingly health conscious customers are placing a premium on natural ingredients in the food, pharmaceutical, beverage, and nutraceutical products they consume.

Alternative processes such as Solvent Extraction and Hydrodistillation leave behind harmful residues. Plus, they distort the ingredient being extracted. That is, the ingredient does not retain its natural purity. Regulations have caught up with public demand and impose exacting conditions to ensure the quality and safety of products by limiting toxic residues. One more reason to rely on CO2 SCFE.

What Makes Supercritical Carbon dioxide (sCO2) an Exceptional SCFE Solvent?

Carbon dioxide and water are the most widely employed supercritical fluids. sCO2 makes such a useful supercritical fluid because it:

• Has a critical temperature of 31.10C, which is around the ambient temperature improving its compatibility with temperature-sensitive compounds;

• Has a more manageable critical pressure of 73.9 bar;

• Is non-flammable and non-toxic;

• Has a customisable density to upgrade its solvent power;

• Is available in ample quantities and in pure form; and

• Has a comparatively low cost.

Although CO2 is a greenhouse gas (GHG), the SCFE process using CO2 becomes eco-friendly if the gas is captured from the atmosphere and recycled.

Carbon dioxide Supercritical Fluid Extraction (CO2 SCFE)

Solvent Extraction employs organic solvents to dissolve the ingredient from the raw material. Later, it separates the organic solvent from the dissolved ingredient. The problem is, organic solvents do not completely disassociate from the ingredient, leaving behind residues.
