Extraction Services Explained

Supercritical CO2 extraction

Is a sophisticated method of extracting bio-actives where the extracts retain biological activity.

Benefits of supercritical C02 extraction:

• High extract yield

• Heat sensitive materials are gently treated

• Extracts and residues are solvent free; making them both saleable unlike other solvent extracts

• Selective extraction and fractionation of extracts is possible

• CO2 is recycled within the plant

• De-selection of heavy metals

Pharmalink have developed a proprietary process to enrich liquid extracts using CO2.

Co-solvent CO2 and Ethanol extraction

Additional benefits of co-solvent extraction:

• Increases extract yield from raw materials that contain polar lipids or with compounds with low solubility in CO2 only.  This is a great benefit for raw materials that contain phospholipids

• Different fractions of polar and non-polar lipids can be separated in this process
