Citral, or 3,7-dimethyl-2,6-octadienal or
lemonal, is either of a pair of
terpenoids with the molecular formula
C10H16O. The two compounds are double bond
isomers. The E-isomer is known as
geranial or citral A. The Z-isomer is known as
neral or citral B.
Geranial has a strong lemon odor. Neral has a lemon odor that's less intense, but sweeter. Citral is therefore an
aroma compound used in perfumery for its citrus effect. Citral is also used as a flavor and for fortifying lemon oil. It also has strong
anti-microbial qualities, and pheromonal effects in insects.
Citral is used in the synthesis of
vitamin A,
ionone, and
methylionone, and to mask the smell of smoke.
Citral is present in the oils of several plants, including
lemon myrtle (90-95%),
Litsea cubeba (70-85%),
lemongrass (65-85%),
Lemon verbena (30-35%),
lemon balm,
lemon and
orange.
Health & Safety information
