If you are aware of how fermentation can enhance the health benefits of certain foods, you must be eager to find out if it is possible to ferment cod liver oil. Cod liver oil is one of the best natural sources of omega 3 fatty acids. It is revered for its ability to control your cholesterol level and improve heart health.
It is believed that the process of fermentation can enhance these benefits. While this is true that fermented cod liver oil does offer numerous benefits, the process of fermentation itself is a bit tricky.
This is so because the process of fermentation basically requires carbohydrates that are used up by organisms to release gases that make the food fermented. Hence, ideally, cod liver oil, being a pure fatty substance, can not be fermented.
So, when the manufacturers “ferment” pure cod liver oil, they do so by extracting the oil from the putrefied cod livers exposed to air and sunlight. This process is commonly referred to as cold-extraction.
As the cod livers are putrefied, there is a release of gas due to the action of bacteria making it a fermented product. Since the process involves the use of salty brine, the process is considered more similar to pickling than fermenting.
Cod liver oil can also be lacto- fermented. Irrespective of the specific process of fermenting cod liver oil, they do offer numerous benefits that can help you stay healthy.
Cod liver oil, when fermented, offers a superior source of several vitamins and omega-3 fatty acids such as EPA and DHA making it a desirable addition to your diet.
Difference between fermented and non-fermented cod liver oil
The process of fermentation is used across various cultures throughout the world as a way to improve the health benefits of substances and preserve them for a longer duration.
Fermentation involves several metabolic processes in which the enzymes in the food undergo changes. It is specifically the carbohydrates in the substance that are converted into an acid or alcohol making it last longer or more shelf-stable.
Similarly, when cod liver oil is fermented, the process is believed to make the oil more stable. Fish oil, being rich in healthy fats such as omega 3 fatty acids, is not very stable and prone to rapid changes in its chemical structure when subjected to heat.
Fermented cod liver oil is considered superior to fresh cod liver oil as the process of fermentation makes it more stable and helps in preserving it for longer without damaging its beneficial elements.
