Volume I of the fourth edition of the Council of Europe's "Blue Book" was

published in 1992 and dealt with chemically-defined flavouring substances.

The Committee of Experts on Flavouring Substances has engaged in a major

toxicological evaluation of the safety-in-use of over 600 natural flavouring

source materials, the conclusions of which will be published in the second

volume. In view of the time required to complete this large task, it was agreed

that reports should be published at regular intervals covering the source

materials so far evaluated. This is the third such report and provides safety-in-use

evaluations of 71 source materials.
