Запах

The odour is warm, powerful and spicy-leathery, with distinctive saffron-like qualities and tobacco undertones. Rose ketone-like floral aspects, herbal nuances and a velvety texture complete it. Further descriptors are phenolic undertones, marine-like facets and woody accents. It is also described as a dry, leathery saffron facet, warm and slightly smoky. At 10% in dipropylene glycol its odour is described as herbal, leather, saffron, iodine, phenolic, tobacco and woody.

What it is

Safraleine is a synthetic aroma molecule with the formula C₁₂H₁₄O and a molecular weight of 174.24. Its chemical name is 2,3,3-trimethylindan-1-one, and it carries the FEMA number 4556. Its JECFA number is 2047, and saffron indenone is another name for it.

Chemistry

Its IUPAC name is 2,3,3-trimethyl-2H-inden-1-one. A second systematic name, 2,3,3-trimethyl-2,3-dihydro-1H-inden-1-one, shows an indanone skeleton with one methyl group on carbon 2 and two on carbon 3.

Properties

It is a colourless to clear yellow liquid. It is practically insoluble or insoluble in water and sparingly soluble in ethanol. Its density is 1.015-1.025 and its refractive index is 1.532-1.542. The partition coefficient log Pow is 2.9 and the vapour pressure is 0.0120 hPa. Its olfactive impact, which is based on the odour detection threshold and the vapour pressure, is rated significant.

Regulation and labelling

It is on the TSCA inventory and has an active REACH registration. Its GHS label carries the pictogram GHS07, the signal word Warning and the hazard statements H412 and H315.

The saffron reference

Natural saffron contains some 28 volatile and aroma-yielding compounds, dominated by ketones and aldehydes. Safranal, the main compound responsible for saffron aroma, is 2,6,6-trimethylcyclohexa-1,3-diene-1-carbaldehyde, with the formula C₁₀H₁₄O. Drying the harvested saffron splits picrocrocin, through heat and enzymes, into glucose and free safranal, which may make up to 70% of the volatile fraction of dry saffron in some samples.
