The permitted list of food additives generally includes specific flavouring substances.
In 2000, the Committee of Experts on Flavouring Substances (CEFS) evaluated estragole and recommended a limit of 0.05 mg/kg (detection limit).
As discussed below, the conclusions of the FEMA Expert Panel are often used as the basis for the acceptance of flavouring substances as safe food ingredients in many countries around the world.
These, like his other dishes have a very distinctive style to them, combining a generosity in flavour and substance with an almost feminine delicacy of presentation.
