Saffron is native to Southwest Asia and is perhaps the most steeply-priced spice of the world by means of weight. It is bitter in flavor and has an iodoform like perfume. This perfume is due to the presence of certain chemical compounds particularly picrocrocin and safranal. A carotenoid dye particularly crocin is answerable for offering golden-yellow hue to dishes while saffron is used as a colouring agent.
Saffron derives its call from a Latin word that means yellow. The domesticated saffron crocus is a perennial flowering plant unknown in wild. The plant is thought to flower in autumn. It is a sterile triploid shape developing in eastern Mediterranean however believed to have originated in Central Asia. C. Cartwrightianus is a variety that has been evolved by way of synthetic selection via loopy plant growers. The plant is sterile and therefore, fails to supply viable seeds. Plants require human help to carry out their reproduction. Corms are used for developing a new plant. A corm survives for one season and upon department it yields up to ten cormlets which produce new flora. Corms are small globules that measure 4.5 cm in diameter.
In the spring season the plant produces about 5-eleven slender and vertically inexperienced leaves every measuring forty cm in duration. In autumn the plant produces purple buds. In October flowering heads appear and that they range in coloration from mild pastel shade of lilac to a darker and extra striated mauve. During the flowering time the plant attains a top of 30 cm. Three prolonged patterns seem from every flower. Each later on gets terminated right into a purple colored stigma measuring 25-30 mm in length.
Saffron vegetation are known to tolerate iciness frosts as much as -10°C and very short intervals of snow cover. Irrigation is needed if now not grown in wet climates like Kashmir wher the average rainfall is 1,000-1,500 mm. Spring rains and drier summers are very vital for plant growth. They are liable to be damaged by digging actions of rabbits, rats, and birds. Nematodes, leaf rusts, and corm rot. They are planted in sloping fashion. In Northern Hemisphere planting is usually completed if June. The vegetation choose friable, loose, low-density, properly-watered, and properly-drained clay-calcareous soils with high natural content.

This crocin in actual phrases is trans-crocetin di-(?-D-gentiobiosyl) ester. Crocins are surely hydrophilic carotenoids which are either monoglycosyl or diglycosyl polyene esters of crocetin. Crocetin is a conjugated polyene dicarboxylic acid that is hydrophobic, and accordingly oil-soluble. When crocetin is esterified with water-soluble gentiobioses, a product is fashioned this is water-soluble. ?-crocin is responsible for making 10% of dry mass of saffron.
