Sesame seed is one of the oldest known oil plants, domesticated more than three thousand years ago. It is known to almost everyone and valued for its slightly nutty flavor as an addition to many culinary products.
The much-loved and widely appreciated Asian cuisine cannot do without sesame seeds or the oil pressed from them. And confectionery connoisseurs can't imagine that there can be no halva. Apart from its taste, sesame is a source of many valuable components - macro and micro elements, fatty acids, amino acids and vitamins. It finds its use both in culinary and in medicine or cosmetology. Its annual production worldwide is approximately seven million tons.
This family includes 13 genera with 70 species. They are plants mainly of dry and sandy habitats and coastal regions. As synanthropic plants (they adapt to life in environments heavily transformed by humans), they are spread as weeds in various parts of the world.
Sesamum is found in Africa, southern Asia and Australia.
It is believed to have originated in Africa, from where it was introduced, first to Asia and later to Europe, where it was considered an invasive species. It is cultivated in tropical regions around the world.
In Europe, it grows in Belgium, France, Greece, Turkey and Cyprus. In Africa, it grows naturally in dry areas south of the Sahara.
Archaeological remains of charred sesame dating to around 3500-3050 B.C. suggest that it was known on the Indian subcontinent at least 5500 years ago. Sesame trade between Mesopotamia and the Indian subcontinent is believed to have occurred in 2000 B.C. It is also thought that sesame was cultivated in Egypt during the Ptolemaic period. The Egyptians called it sesemt, and the name is found on a list of medicines in the scrolls of the Ebers Papyrus dating back more than 3,600 years.
Excavations of Tutankhamun's tomb uncovered baskets of sesame, among other tomb goods.
It is widely naturalized in tropical regions around the world. Sesame has many species, most of which are wild and native to sub-Saharan Africa. The most common cultivated variety is Indian sesame (Sesamum indicum).
It has an erect, branched stem covered with glandular hairs. The lower leaves are petioled and round; the middle are large, toothed, broadly lanceolate, on long petioles; the upper leaves are short-tailed, narrowly lanceolate, and entire-edged.
Indian sesame flowers are white or purple with red spots. They are large (up to 3 cm long) and self-pollinating.
The fruit is 4-, 6- or 8-seeded, green, heavily mossy bags, which burst when ripe. The pouch contains about 80 seeds.
The seeds are flat and opaque with variable colors from white, which is the most prized, to almost black.
They mainly belong to the group of unsaturated fatty acids: omega-9, omega-6 and omega-3. These acids, in addition to their health-promoting effects, also help burn unnecessary body fat.
Sesame also contains oleic fat, which is an essential factor in the prevention of atherosclerosis. Oil made from sesame seeds helps prevent breast cancer, prostate cancer and, most importantly, melanoma - a skin cancer.
