Sardine oil is a versatile substance used in manufacturing as a lubricant, in paints, varnishes, linoleum, biofuels, and soap. It is also a rich source of omega-3 fatty acids, which have nutritional and health benefits, including reducing triglyceride levels and the risk of some types of cancer. The oil is extracted from sardines through a process of cutting, cooking, centrifuging, and purifying. It is available for consumption in capsules or as a dietary supplement.
Sardine oil is a type of oil harvested from small herring-like fish known as sardines. The oil is widely used in manufacturing. It also has nutritional benefits, similar to the oils in other types of fish like salmon.
A variety of companies use sardine oil as a lubricant. The substance is a common ingredient in paints, varnishes, linoleum and even biofuels. Soap is another product in which sardine oil is used. The fact that people use sardine oil in so many capacities other than ingesting the oil has led to jokes that sardine oil is one of the few substances that works just as well in the body as it does in a car or on the someone’s wall.
Nutritionally, sardine oil is one of the richest sources of omega-3 fatty acids, next to salmon oil. Scientists believe these fatty acids are essential for the absorption of calcium, which is a requirement for strong bones. It also aids in other physical processes such as blood clotting, transmission of nerve impulses, and protein structuring.
Another health benefit of the omega-3 fatty acids found so abundantly in sardine oil is the reduction in triglyceride levels. High triglyceride levels are associated with plaque buildup in the arteries, which can raise blood pressure and damage the heart. Doctors may not consider sardine oil to be a cure for cancer, but the omega-3 fatty acids in the oil have been shown to reduce the risk of some types of cancer.
Extracting oil from sardines involves the same basic process as extracting oil from other fish. The workers cut and cook the sardines with steam. Then they centrifuge the fish to separate the oil and water from the fish pulp or fishmeal. After meal and liquid separation, workers separate oil and water. The oil is then purified and antioxidants are added before packaging if the oil is for consumption.
For industrial purposes, sardines are placed in large bottles or tubs. People often choose to ingest sardine oil by eating sardine fish. Sardines have a rather strong taste and smell, so for people who don’t mind the taste, sardines are available in capsules. Ingesting sardine oil in this way is quite simple, as the person taking the capsule cannot directly taste the oil. This type of oil is available in most health food stores, as well as online for both nutritional and industrial purposes.
