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
