Fish oil can be made from one or several different kinds of fish. The products commonly found in the market are made from the body oil of sardines, mackerel, herring, salmon, or from the liver oil of cod fish. There are also other “fish oils” made from squid and green lipped mussels as well.
Before, one of the biggest turn off of cod liver oil was that its taste was horrible. You may have heard of people who were forced to take cod liver oil in childhood. This problem has largely been solved in today’s version of fish oil through improved processing, the addition of flavours to mask the taste, and the reduced use of fermented oil thanks to refrigeration.
There are methods used to ensure that heavy metal content is minimal in fish oil products. Different methods of processing help reduce the heavy metals in fish oil products, as well as limiting oxidation of the oil.
Like any oil, fish oil can go rancid if it’s left in open air. Because of this, bottles of liquid fish oil are often “capped” with nitrogen gas during the manufacturing process to help prevent oxidation.
Encapsulating fish oil (having it in capsule form) instead of leaving it as a liquid is another way to prevent oxidation of the oil. As an added benefit, capsules don’t need to be refrigerated!
Moreover, it can be consumed in various forms. These include eating the fish directly by baking, roasting, frying, grilling, broiling, or smoking it. It can also be consumed in the form of concentrated dietary supplements like liquid, tablet, capsule, pill, or soft gels. Also, there are various pharmaceutical grades of the oil.
For people without allergies or diet restrictions, fish oil products are the most suitable source of omega-3 fatty acids due to their high bioavailability, low cost, and accessibility for the patient.
Omega-3 fatty acids associated with positive health effects are eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Other useful essential fatty acids in fish oil include alpha-linolenic acid or ALA and gamma-linolenic acid or GLA.
Fish oil is a well tolerated and traded product around the world.
Fish can be reduced to oil following these processing steps:
- Heating, which coagulates the protein, ruptures the fat depots and liberates oil and physico-chemically bound water;
pressing (or occasional centrifugation), which removes a large fraction of the liquids from the mass;
- Separation of the liquid into oil and water (stickwater). This step may be omitted if the oil content of the fish is less than 3%;
- Evaporation of the stickwater into a concentrate (fish solubles);
- Drying of the solid material (presscake) plus added solubles, which removes sufficient water from the wet material to form a stable meal,
grinding the dried material to the desired particle size.
Although the process may appear few and simple, a variety of elements is required to make a smooth running and profitable factory. There are also different types of equipment that will do the same job but in different ways.
The World Health Organization (WHO) recommends eating 1–2 portions of fish per week. This is because the omega-3 fatty acids in fish provide many health benefits, including helping protect against a number of diseases.

Skin care.
Despite the many benefits of fish oil, an excessive intake of it can have adverse allergies and side effects on the body, so it is necessary to consume fish oil supplements cautiously.
Fish oil can also be consumed in the form of concentrated dietary supplements like liquid, tablet, capsule, pill, or soft gels. It is required in the pharmaceutical industries around the world to make some dietary supplements.
As a result, investing in fish oil processing and production for local sale or export is highly profitable and rewarding.
The most important prerequisite for a profitable fish oil business is an ample and regular supply of raw material at an acceptable price and one can be sure of good returns on investment.
