Abstract:
Benzoin balsam is an anthropic exudate obtained from the bark of several species of Styrax trees that is mainly used as a perfume fixative as well as a flavouring agent. Benzoe tonkinensis Laos (also commercialized under the denomination Siam benzoin balsam) displaying characteristic vanilla notes and already being largely used to flavour all kinds of edible goods, was intended to be proposed by Agroforex Company to the Codex Committee on Food Additives for evaluation as a food additive. For this purpose, the present paper reports the phytochemical characterisation of both the volatile and non-volatile fractions of benzoin balsams and the quantitation of some of the major components by gas and liquid chromatography techniques. Four coniferyl and two morinol derivatives were characterised for the first time in Benzoe tonkinensis Laos. Finally, two liquid chromatographic methods used to easily discriminate Siam from Sumatra balsam (also known as Benzoe sumatranus Indonesia) were developed.
