Argan oil  Argan oil is a plant oil produced from the kernels of the argan tree ("Argania spinosa" L.) that is endemic to Morocco. In Morocco, argan oil is used to dip bread in at breakfast or to drizzle on couscous or pasta. It is also used for cosmetic purposes. Argan oil consists mostly of fatty acids:  Argan oil has a relative density at ranging from 0.906 to 0.919. Argan oil contains tocopherols (vitamin E), phenols, carotenes, squalene, and fatty acids, (80% unsaturated fatty acids) The main natural phenols in argan oil are caffeic acid, oleuropein, vanillic acid, tyrosol, catechol, resorcinol, (−)-epicatechin and (+)-catechin. Depending on the extraction method, argan oil may be more resistant to oxidation than olive oil. In Morocco, the oil is used exclusively as a foodstuff, for dipping bread, or on couscous, and for medicinal use. Amlou, a thick brown paste with a consistency similar to peanut butter, is used locally as a bread dip. It is produced by grinding roasted almond and argan oil using stones, and then mixing the argan oil and almonds in honey. Various claims about the beneficial effects on health due to the consumption of argan oil have been made. A research article published in 2010 found that argan oil contained higher levels than other oils of γ-Tocopherol, which possesses strong chemopreventive and anti-inflammatory properties. Shea Terra Organics was the first company to launch argan oil in the USA in 2003. Since this time argan oil has become increasingly popular in cosmetic and hair care preparations. , the biggest growth in demand is in the cosmetics industry, where it is being used for face creams and as an ingredient in lip gloss, shampoo, moisturisers and soaps. The fruit of the argan tree is small, and round, oval, or conical. A thick peel covers the fleshy pulp. The pulp surrounds a hard-shelled nut that represents about 25% of the weight of the fresh fruit. The nut contains one to three oil-rich argan kernels. Extraction yields from 30% to 50% of the oil in the kernels, depending on the extraction method. It takes about of dried argan fruit to produce only one litre of oil.
