Argan
Encyclopedia
The Argan is a species of tree
endemic to the calcareous
semi-desert Sous
valley of southwestern Morocco
and to the Algerian region of Tindouf
in the western Mediterranean region. It is the sole species in the genus Argania.
Argan grows to 8-10 metres high and live up to 150–200 years. They are thorny, with gnarled trunks. The leaves
are small, 2–4 cm long, oval with a rounded apex. The flower
s are small, with five pale yellow-green petals; flowering is in April. The fruit
is 2–4 cm long and 1.5–3 cm broad, with a thick, bitter peel surrounding a sweet-smelling but unpleasantly flavoured layer of pulpy pericarp. This surrounds the very hard nut, which contains one (occasionally two or three) small, oil-rich seeds. The fruit takes over a year to mature, ripening in June to July of the following year.
Biosphere reserve
. Their area has shrunk by about half during the last 100 years, owing to charcoal-making, grazing, and increasingly intensive cultivation. The best hope for the conservation of the trees may lie in the recent development of a thriving export market for argan oil
as a high-value product, although this has been questioned recently .
Argan is also grown in Israel
, in the Arava
and Negev
.
In some parts of Morocco, argan takes the place of the olive
as a source of forage

, the argan tree is frequently climbed by goats http://www.the-tree.org.uk/SpecialBranch/InTree/goats.htm.
Argan fruit falls in July, when black and dry. Until this happens, goats are kept out of the argan woodlands by wardens. Rights to collect the fruit are controlled by law and village traditions. The leftover nut is gathered after consumption by goats.
Argan oil is produced by several women's co-operatives in the southwestern parts of Morocco. The most labour-intensive part of oil-extraction is removal of the soft pulp (used to feed animals) and the cracking by hand, between two stones, of the hard nut. The seeds are then removed and gently roasted. This roasting accounts for part of the oil's distinctive, nutty flavour.
The traditional technique for oil extraction is to grind the roasted seeds to paste, with a little water, in a stone rotary quern. The paste is then squeezed by hand in order to extract the oil. The extracted paste is still oil-rich and is used as animal feed. Oil produced this way can be stored and used for 3–6 months, and will be produced as needed in a family, from a store of the kernels, which will keep for 20 years unopened. Dry-pressing is becoming increasingly important for oil produced for sale, as this method allows for faster extraction, and the oil produced can be used for 12–18 months after extraction.
The oil contains 80% unsaturated fatty acids, is rich in essential fatty acids and is more resistant to oxidation than olive oil. Argan oil is used for dipping bread, on couscous
, salad
s and similar uses. A dip for bread known as amlou is made from argan oil, almond
s and peanut
s, sometimes sweetened by honey
or sugar. The unroasted oil is traditionally used as a treatment for skin diseases, and has become favoured by European cosmetics manufacturers.
Argan oil is sold in Morocco as a luxury item, and is difficult to find for sale outside the region of production. The product is of increasing interest to cosmetics companies in Europe. It used to be difficult to buy the oil outside Morocco, but since 2001-2002 it has become a fashionable product in Europe and North America. It is now widely available in specialist shops and occasionally in supermarkets. Its price (USD
$40-50 for 500 ml) is notable compared to other oils.
