Watermelon seed oil is extracted by pressing from the seeds of the Citrullus lanatus (watermelon). It is particularly common in West Africa, where it is also called ootanga oil.
The common watermelon most likely originated almost 5,000 years ago in the Kalahari Desert. Its wild ancestor, the Kalahari Melon, still grows there, and its seeds are pressed for their oil. Watermelons migrated north through Egypt, and during the Roman era they were cultivated and prized. [1]
Like their wild ancestors, modern domestic watermelon seeds can be pressed for oil. Traditionally, the seeds are extracted from the seed casing, and dried in the sun. Once dried, the seeds are pressed.
Watermelon seed oil contains high amounts of unsaturated fatty acids, primarily linoleic and oleic acids. [2]

A melon is any of various plants of the family Cucurbitaceae with sweet, edible, and fleshy fruit. The word "melon" can refer to either the plant or specifically to the fruit. Botanically, a melon is a kind of berry, specifically a "pepo". The word melon derives from Latin melopepo, which is the latinization of the Greek μηλοπέπων (mēlopepōn), meaning "melon", itself a compound of μῆλον (mēlon), "apple", treefruit " and πέπων (pepōn), amongst others "a kind of gourd or melon". Many different cultivars have been produced, particularly of cantaloupes.
Vegetable oils, or vegetable fats, are oils extracted from seeds or from other parts of fruits. Like animal fats, vegetable fats are mixtures of triglycerides. Soybean oil, grape seed oil, and cocoa butter are examples of seed oils, or fats from seeds. Olive oil, palm oil, and rice bran oil are examples of fats from other parts of fruits. In common usage, vegetable oil may refer exclusively to vegetable fats which are liquid at room temperature. Vegetable oils are usually edible.
Hemp oil is oil obtained by pressing hemp seeds. Cold pressed, unrefined hemp oil is dark to clear light green in color, with a nutty flavor. The darker the color, the grassier the flavour. It should not be confused with hash oil, a tetrahydrocannabinol-containing oil made from the Cannabis flower.
Sclerocarya birrea, commonly known as the marula, is a medium-sized deciduous fruit-bearing tree, indigenous to the miombo woodlands of Southern Africa, the Sudano-Sahelian range of West Africa, the savanna woodlands of East Africa and Madagascar.
Grape seed oil is a vegetable oil derived from the seeds of grapes. A by-product of the winemaking industry, it is typically used for edible applications.
Walnut oil is oil extracted from walnuts, Juglans regia. The oil contains polyunsaturated fatty acids, monounsaturated fatty acids, and saturated fats.
Lauric acid, systematically dodecanoic acid, is a saturated fatty acid with a 12-carbon atom chain, thus having many properties of medium-chain fatty acids. It is a bright white, powdery solid with a faint odor of bay oil or soap. The salts and esters of lauric acid are known as laurates.
Citrullus colocynthis, with many common names including Abu Jahl's melon,colocynth, bitter apple, bitter cucumber, egusi, vine of Sodom, or wild gourd, is a desert viny plant native to the Mediterranean Basin and Asia, especially Turkey, and Nubia.
Egusi, also known as agusi, ohue, Ikpan, Ikon, or agushi) is the name for the protein-rich seeds of certain cucurbitaceous plants, which, after being dried and ground, are used as a major ingredient in West African cuisine.
The cuisine of Botswana is unique but shares some characteristics with other cuisines of Southern Africa. Examples of Setswana food include pap, samp, vetkoek, bogobe and mophane worms. A food unique to Botswana is seswaa, salted mashed-up meat.
Cucumis myriocarpus, the gooseberry cucumber, gooseberry gourd, paddy melon, Mallee Pear or prickly paddy melon is a prostrate or climbing annual herb native to tropical and southern Africa. It has small, round, yellow-green or green-striped fruit with soft spines, small yellow flowers and deeply lobed, light green leaves. The melon occurs in disturbed soil and cleared or bare areas, and thrives on summer moisture.
Southern Exposure Seed Exchange (SESE) is a cooperatively-owned seed company. SESE is a source for heirloom seeds and other open-pollinated (non-hybrid) seeds with an emphasis on vegetables, flowers, and herbs that grow well in the Mid-Atlantic region. SESE also supports seed saving and traditional seed breeding through their product line, through lectures and workshops, and by working with over 50 small seed-growing farmers in the Mid-Atlantic and other parts of the United States. SESE publishes an intermittent email newsletter and blog for gardeners, as well as the Southern Exposure Seed Exchange Catalog and Garden Guide.
The citron melon, also called Citrullus lanatus var. citroides and Citrullus amarus, fodder melon, preserving melon, red-seeded citron, jam melon, stock melon, Kalahari melon or tsamma melon, is a relative of the watermelon. It is in the family Cucurbitaceae which consists of various squashes, melons, and gourds. Native to arid landscapes of sub Saharan Africa, it has been a wild source of nutrition and hydration for humans for an extraordinarily long time. Its fruit has a hard white flesh, rendering it less likely to be eaten raw in modern times; more often it is pickled or used to make fruit preserves, and is used for cattle feed. It is especially useful for fruit preserves, because it has a high pectin content.
Citrullus ecirrhosus, commonly known as Namib tsamma, is a species of perennial desert vine in the gourd family, Cucurbitaceae, and a relative of the widely consumed watermelon. It can be found in both Namibia and South Africa, in particular the Namib Desert. It is the sister species to the bitter melon, Citrullus amarus with which it shares hard, white and bitter flesh.
Cucumeropsis mannii is a species of melon native to tropical Africa west of the East African Rift, where it is grown for food and as a source of oil.
Ximenia americana, commonly known as tallow wood, hog plum, yellow plum, sea lemon, or pi'ut (Chamorro), is bush-forming shrub/small tree; a species from the Ximenia genus in the Olacaceae family. It is mainly found in the tropics, ranging from Africa, India and southeast Asia, to Australia, New Zealand, Pacific Islands, West Indies, Central, North and South America. It is especially common in Africa and South America. It is not domesticated so it is only found occurring in the wild.
Watermelon is a flowering plant species of the Cucurbitaceae family and the name of its edible fruit. A scrambling and trailing vine-like plant, it is a highly cultivated fruit worldwide, with more than 1,000 varieties.
Allanblackia oil is a vegetable oil that comes from the seeds of trees of the genus Allanblackia. This tree can be found in the wet tropical belt of Africa. Because of its unique blend of fatty acids, the oil from Allanblackia seeds has melting properties that make it excellent to use as structuring fat in food products, e.g. margarines.
Kalahari melon oil also known as Tsamma (Damara/Nama), wild watermelon (English), bitterboela, karkoer (Afrikaans), wild watermelon, makatane (Setswana) or Mokaté oil, is a plant oil, extracted from the seeds of the Kalahari melon (Citrullus vulgaris), which is endemic to the Kalahari Desert, spanning Namibia, Botswana and South Africa. Being one of 1,200 varieties of melon, Kalahari melon oil is distinct from regular watermelon seed oil. The seed of the Kalahari melon consists of approximately 50% oil, 35% protein and 5% dietary fibre.
