Animal fat processing

Animal fats and fish oils are currently much in focus because of their content of high-value Omega-3 unsaturated fatty acids. These are necessary for human health, but the human body is unable to produce them. Alfa Laval provides the unique combination of technology and know-how required to extract high-value proteins from animal and fish products.

Animal and fish fat refining

Special treatment

Processing with a focus on Omega-3 necessitates effective removal of PCBs (polychlorinated biphenyls), any residual amounts of DDT and any POCs (persistent organic chemicals) that may be present.

Alfa Laval provides chemical refining systems and other specialist equipment capable of removing any such traces.


An alternative, more natural, approach is fractionation. This involves gentle cooling of the fats and oils under carefully controlled conditions, making it possible to crystallize the hard fat content so it becomes relatively easy to remove.

We provide the crystallization and filtration equipment essential for this kind of fats modification.
