Traditional technologies in many cases do not offer a satisfactory solution to a specific problem. Furthermore, there is a continuous search to reduce production costs. Pilot scale studies may show that, despite initial high capital costs, operating costs would be lower and the overall feasibility can be proven at certain scale of operation. In addition, supercritical technology allows:
This is the case of light flours obtained from the extraction of waxes and oils: the protein content of the exhausted product is increased due to the subtraction of fatty compounds, like flours without fats from almonds. It is the case of vegetable waxes separated from the compounds.
Other advantages that SC-CO2 technology has demonstrated in the extraction of special oils include:
SC-CO2 is a non-polar FDA-approved solvent (GRASP).
