What makes this variety of samphire so special is the quantity, and the high quality, of the oil it yields. The oil content of the plant's seeds is about 30 percent of its total weight?compared with 17 to 20 percent for the soybean, according to tests by the University of Arizona's Environmental Research Laboratory (ERL) in Tucson, which has spearheaded Salicornia development. Salicornia oil also contains 72 percent linoleic acid?a healthy polyunsaturated fat. That's close to the level found in safflower oil, and more than twice that of oil from soybeans.
Salicornia grows in desert irrigated by sea water!
