"Cultivated in the main Kashmir valley. Being a triploid it is sterile and propagated by vegetative means only. Known only under cultivation; Saffron, obtained from long red style branches and stigmas are in great demand for eastern culinary preparations and in medicine. It is rich in vitamin B2."

| The freshly picked stigmas are nearly odorless, with typical saffron flavor being developed during the drying process. The aroma description of β-isophorone (3,5,5-trimethyl-3-cyclohexen-1-one) is "saffron, floral and hay". \\ |

"Safranal, the main component of Crocus sativus essential oil, is thought to be the main cause of saffron unique odor... Beside its exclusive color, saffron presents a particular taste which is originates from its picrocrocin content. Safranal (2,6,6-trimethyl-1,3-cyclohexadien-1-carboxaldehyde) is a cyclical terpenic aldehyde produced from picrocrocin. [[https://en.wikipedia.org/wiki/Picrocrocin|Picrocrocin]], discovered by Kajser (1884), cracks down following acids and alkali conditions, resulting in a molecule of water and an aglycon which in turn, loses a water molecule and finally turns to safranal. Kuhn and Winterstein (1933), who obtained safranal through picrocrocin hydrolyzation for the first time, named this chemical as //Safranal//." \\ | "Safranal, the main component of Crocus sativus essential oil, is thought to be the main cause of saffron unique odor...

| Minor components present in all samples were 2(5H)-furanone, camphene, myrcene, α-phellandrene, δ-3-carene, α-terpinene, p-cymene and 4-methylene isophorone. [[http://www.thegoodscentscompany.com/data/rw1506341.html|β-Isophorone]] is considered one of the quality marker compounds - 70% of samples analyzed in the study contained β-isophorone. \\ |
