Solvent/Chemical Extraction Methods. Most manufacturers today use some form of solvent based extraction. In simple terms, solvent based extraction uses a liquid or chemical of some kind in this case, often hexane to separate oil from the krill themselves. Once the chemical solvent is added, the solid bits of krill are filtered out.
