Mechanical Extraction and Initial Processing Pressing and Separation Once the fish are delivered, the process of extraction begins. Understanding how is fish oil made reveals the meticulous science and technology required to transform a raw marine resource into a stable, bioavailable product.
Industrial Fish Oil Production: From Pressing to Purification
These compounds are not synthesized by humans and must be obtained through diet or supplementation. This mechanical pressing separates the liquid fraction, which contains the fish oil, from the solid residual cake known as press cake.
This sophisticated thermal separation process occurs under a vacuum, which lowers the boiling point of the compounds. The oil is heated to a specific temperature where the volatile triglycerides and free fatty acids evaporate.

Subsequently, the oil is passed through bleaching earth, such as activated charcoal or clay, which adsorbs any remaining color pigments and other minor impurities. The journey of fish oil from a whole fish to a purified capsule involves a sophisticated sequence of steps designed to maximize potency and ensure safety.
