In the process of fishmeal processing, not only can we obtain high-protein fishmeal, but also separate the fish oil, which is rich in nutritional value, from the raw material. With the improvement of the comprehensive utilization rate of aquatic by-products, its extraction is becoming an important part of the fish meal production line.

This article will analyze in detail why it should be separated from fishmeal production and what its uses are.

Where does fish oil come from?

The fish body naturally contains a certain proportion of oil, especially in some deep-sea fish or oil-rich fish. In the steaming and pressing stages of fishmeal production, the raw fish is treated at high temperatures and the oil is gradually released. The steamed raw fish is then separated by the pressing equipment and enters the oil-water separation system.

In this way, dry fishmeal and liquid fish oil can be obtained at the same time, maximizing the use of resources.

Why extract fish oil?

After extracting, the fishmeal has the following advantages:

• Effectively improve the physical properties and storage stability of fishmeal.
• The separated fish oil itself is a high-value by-product that can be used in multiple fields such as feed, chemicals, medicine, and health products to increase overall profits.

If not extracted, the fishmeal has high oil content, which is not easy to store, easy to oxidize and deteriorate, and will reduce the quality and shelf life of fishmeal.

What are the uses of fish oil?

It has a wide application in many fields:

• Animal feed and pet food additives
  • It’s rich in Omega-3 fatty acids and is a high-quality nutritional additive.
• Human healthcare products
  • It’s used to make deep-sea fish oil capsules, for functions such as lowering blood lipids and enhancing immunity.
• Cosmetic and lubricant industries
  • As a versatile natural resource, it’s added to the cosmetic or lubricant industries.
