Saffron (/ˈsæfrən, -rɒn/ SAF-rən, -ron; Persian: زعفران, romanized: zafarān) is a spice derived from the sterile autumn-blooming flower of Crocus sativus, commonly known as the "saffron crocus". The vivid crimson stigma and styles (in industry jargon: 'threads') are collected and dried for use mainly as a seasoning and colourant in food. Saffron crocus was slowly propagated throughout much of Eurasia and later brought to parts of North Africa, North America, and Oceania.
Saffron's taste and iodoformic 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. Saffron quality is objectively measured under the ISO 3632 standard, which evaluates the concentration of active phytochemicals—specifically crocin (color), picrocrocin (taste), and safranal (aroma) via spectrophotometric laboratory analysis. The grading depends largely on the ratio of dark red stigmas to yellow styles, with higher concentrations of red parts yielding premium-grade products. Although market prices fluctuate, premium saffron regularly exceeds US$5,000 per kilogram, sustained by its labor-intensive hand-harvesting process. (Full article...)
