Recipe: How to make fermented ratfish liver oil?
The ratfish, a little-known group of shark relatives (known also as rabbit fish), has been a source of nutritious oil for centuries – especially in Scandinavian countries.
This oil, known as ratfish liver oil (RLO) is rich in vitamins A and D, omega fatty acids, and alkylglycerols, making it a valuable supplement for maintaining healthy cholesterol levels, heart health, and skin. [2].
Now, although you can purchase ratfish olive oil online and avoid getting your hands dirty, you will not find fermented ratfish liver oil that easily because of the extra step and significant time the fermentation process adds to the end product.

Fermented Ratfish Liver Oil vs Non-fermented RLO
What’s the difference between fermented Ratfish Liver Oil and Non-fermented RLO?
The main difference between fermented Ratfish Liver Oil and non-fermented RLO is the fermentation process. Fermented Ratfish Liver Oil undergoes a fermentation process which involves the breakdown of organic compounds by microorganisms such as bacteria or yeast.
You essentially ferment ratfish liver first and then you extract it’s oil.
Non-fermented Ratfish Liver Oil, on the other hand, is taken directly from the liver of the Ratfish without undergoing any fermentation process. It is typically processed and purified to remove impurities.
The fermentation process enhances the nutrient content and bioavailability of the oil, while non-fermented RLO is produced without this step.
Fermented Ratfish Liver Oil can lead to changes in its nutrient content. For example, fermentation can increase the concentration of certain beneficial compounds such as bioactive peptides, antioxidants, and probiotics.
It can also contain higher levels of vitamin K2 and other beneficial compounds.
However, the specific nutrient content and health benefits of fermented and non-fermented RLO may vary depending on the production methods and quality of the oil.
Fermented Ratfish Liver Oil may also have a “stronger” taste and smell because of the fermentation process.
Non-fermented Ratfish Liver Oil is more readily available and commonly found in the market compared to fermented RLO. The fermentation process adds an extra step and time to the production process, which can increase the cost of the final product.
