The first step involves cooking the fish material, which helps to coagulate proteins and facilitates the separation of solids from liquids. Furthermore, the sourcing location is critical; colder waters typically yield fish with higher oil concentrations.

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. This sophisticated thermal separation process occurs under a vacuum, which lowers the boiling point of the compounds.
This step is crucial for preventing the oil from becoming cloudy when refrigerated. The raw fish oil exiting the press is a crude product containing triglycerides, free fatty acids, water, and impurities.
Deep Dive into the Fish Oil Refining Process Steps
Fish oil is celebrated for its high concentration of long-chain omega-3 fatty acids, specifically eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). This step removes phospholipids—often referred to as "gums"—which cause cloudiness.
