Here, an alkaline solution is added to saponify and remove free fatty acids, which are responsible for the rancid taste associated with poor-quality oil. 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 oil is heated to a specific temperature where the volatile triglycerides and free fatty acids evaporate. Molecular Distillation: The Critical Purification Step Perhaps the most critical phase in manufacturing how is fish oil made is molecular distillation.
The chemical reaction causes these impurities to separate from the oil, allowing them to be washed away, leaving behind a cleaner, more stable substance. These vapors then travel across a condenser where they cool and separate from contaminants like heavy metals, dioxins, and polychlorinated biphenyls (PCBs).

Formulation, Stabilization, and Encapsulation. These species are chosen for their high oil content and rapid reproduction rates, which contribute to sustainability.
