The Fish Oil Manufacturing Process

The fish oil manufacturing process is intricate and involves several steps, including refining, decolorization, deodorization, mixing, and stabilization.  It begins with crude fish oil and results in a stable, high-quality product suitable for human consumption.

The first step in the manufacturing process involves mixing of different crude fish oils to create the desired EPA-DHA profile. To ensure that the mixture’s profile is correct, a laboratory analysis of the oil’s fatty acid content is performed.


Next, a series of automatic procedures are performed on the oil to neutralize free acids. This causes the free fatty acids to form a paste, which is separated from the neutralized oil in a centrifuge. This oil is then washed with warm water to remove any small particles of paste that may still be present.


After the oil has been washed, it will be passed into a container to remove moisture. While in the container, the oil is subjected to a vacuum treatment. After this step is complete, the oil will be transferred to another container. Silica is added to the oil to eliminate any remaining moisture or paste.

Using a filtering process, the manufacturer separates the silica from the oil. Next, the oil is combined with active carbon and a mix of decolorizing earths to decolorize it and remove contaminants. After 30 minutes of incubation, the manufacturer filters out these substances.


Without deodorization, fish oil would have a strong fishy taste and smell. To deal with this issue, the manufacturer injects water vapor into the oil, which removes the particles that cause the odor and smell through evaporation.


To stabilize the fish oil, the manufacturer adds an antioxidant blend containing food grade antioxidants, such as tocopherols. The resulting mixture is transferred to stainless steel storage containers.

The final step in the manufacturing process is packaging. During this step, the oil is packaged according to the client’s specifications. fish oil manufacturing process image 2.jpg
