Saffron
Summary
Saffron (ˈsæfrən,_-rɒn) is a spice derived from the flower of Crocus sativus, commonly known as the "saffron crocus". The vivid crimson stigma and styles, called threads, are collected and dried for use mainly as a seasoning and colouring agent in food. Although some doubts remain on its origin, it is believed that saffron originated in Iran. However, Greece and Mesopotamia have also been suggested as the possible region of origin of this plant. Saffron crocus slowly propagated throughout much of Eurasia and was later brought to parts of North Africa, North America, and Oceania.
Saffron's taste and iodoform-like or hay-like fragrance result from the phytochemicals picrocrocin and safranal. It also contains a carotenoid pigment, crocin, which imparts a rich golden-yellow hue to dishes and textiles. Its recorded history is attested in a 7th-century BC Assyrian botanical treatise, and it has been traded and used for thousands of years. In the 21st century, Iran produces some 90% of the world total for saffron. At US$5,000 per kg or higher, saffron has long been the world's costliest spice by weight.
A degree of uncertainty surrounds the origin of the English word "saffron". It might stem from the 12th-century Old French term safran, which comes from the Latin word safranum, from the Arabic (زَعْفَرَان), za'farān, which comes from the Persian word zarparan meaning "gold strung" (implying either the golden stamens of the flower or the golden color it creates when used as flavor).
Crocus sativus
The domesticated saffron crocus, Crocus sativus, is an autumn-flowering perennial plant unknown in the wild. It probably descends from the eastern Mediterranean autumn-flowering Crocus cartwrightianus which is also known as "wild saffron" and originated in Crete or Central Asia. C. thomasii and C. pallasii are other possible sources. As a genetically monomorphic clone, it slowly propagated throughout much of Eurasia.
It is a sterile triploid form, which means that three homologous sets of chromosomes make up each specimen's genetic complement; C.
