as wild flax or false flax oil). It was possibly brought to North America unintentionally as a weed with flaxseed, and has had limited commercial importance until modern times. Currently, the breeding potential is unexplored compared to other oilseeds commercially grown around the world. Uses The seed oil was used in the kitchen or burnt in lamps. Human food The crop is now being researched due to its exceptionally high level (up to 45%) of omega-3 fatty acids, which is uncommon in vegetable sources. Seeds contain 38 to 43% oil and 27 to 32% protein. Over 50% of the fatty acids in cold-pressed camelina oil are polyunsaturated. The oil is also very rich in natural antioxidants, such as tocopherols, making this highly stable oil very resistant to oxidation and rancidity. It has 1–3% erucic acid; recently, several low-erucic and zero-erucic Camelina sativa varieties (with erucic acid content of less than 1%) have been introduced. The vitamin E content of camelina oil is approximately 110 mg/100 g. It is well suited for use as a cooking oil as it has an almond-like flavor and aroma. Traditional Speciality Guaranteed The oil is registered under the name "Olej rydzowy tradycyjny" as a Traditional Speciality Guaranteed product in the European Union and the United Kingdom. Biodiesel and jet fuel The US state of Montana has recently been growing more camelina for its potential as a biofuel and biolubricant. Plant scientists at the University of Idaho, Washington State University, and other institutions also are studying this emerging biodiesel. Studies have shown camelina-based jet fuel reduces net carbon emissions by about 80%. The United States Navy chose it as the feedstock for their first test of aviation biofuel, and successfully operated a static F414 engine (used in the F/A-18 Hornet and F/A-18E/F Super Hornet) in October 2009 at Naval Air Station Patuxent River, Maryland. The United States Air Force also began testing the fuel in its aircraft in March 2010. On 22 April 2010, the U.S. Navy observed Earth Day by conducting a flight test lasting about 45 minutes at Naval Air Station Patuxent River of an F/A-18 Super Hornet – nicknamed the "Green Hornet" – powered by a 50/50 blend of conventional jet fuel and a biofuel made from camelina; the flight was the first of a planned 15 test flights totaling about 23 flight-hours, scheduled for completion by mid-June 2010. In March 2011, the
