"Cassione.RTM (registered trade mark of the company
Firmenich).", or 4-(3,4-methylenedioxyphenyl)-butan-2-one, had not been
found in nature until recently. For this reason, outside perfumery, its
use had only been authorised in artificial food flavourings. Its presence
was recently established in the essential oil of the aerial part of the
rue plant: Ruta angustifolia Pers., a plant which is self-sown and grows
in Malaysia (D. Joulain et al., Journal of Essential Oil Research, 1991,
3, 355), and it is therefore possible to now use this substance in food
flavourings labelled "natural". |
