SAFRANAL Usage And Synthesis

Chemical Properties

2,6,6-Trimethylcyclohexa-1,3-dienyl methanal has a characteristic saffron-like odor and taste.

Occurrence

Occurring naturally as a glucoside (picrocrocin) in saffron. Also reported found in grapefruit juice, saffron, black tea, green tea, microbial fermented tea, Bourbon vanilla, lemon balm, grapefruit juice, maté and sweet grass oil.

Uses

Safranal, is isolated from Saffron, and is primarily responsible for the aroma of saffron. It has also been shown to have anticonvulsant properties, acting as agonist at GABAA receptors. It is also possessing anticancer and antidepressant properties.

Definition

ChEBI: A monoterpenoid formally derived from beta-cyclocitral by dehydrogenation.

Preparation

By acid hydrolysis of picrocrocin, the bitter principle in saffron; by catalytic dehydrogenation of β-cyclocitral or α-cyclogeranic acid with selenium dioxide.

Taste threshold values

Taste characteristics at 1 ppm: woody, medicinal, spicy and camphoraceous with a fruity and herbal nuance.
