Scientific Opinion


The Panel on Food Contact Materials, Enzymes, Flavourings and Processing Aids (CEF) of the EFSA was requested to consider evaluations of flavouring substances assessed since 2000 by the Joint FAO/WHO Expert Committee on Food Additives (the JECFA), and to decide whether further evaluation is necessary, as laid down in Commission Regulation (EC) No 1565/2000. The present consideration concerns a group of 10 tetrahydrofuran derivatives and one furanone derivative evaluated by the JECFA at the 63rd meeting in 2004. This revision is made due to additional toxicity data have become available for anhydrolinalool oxide (5) [FL-no: 13.097]. The substances were evaluated through a stepwise approach that integrates information on structure-activity relationships, intake from current uses, toxicological threshold of concern, and available data on metabolism and toxicity. The JECFA concluded all the 11 tetrahydrofuran derivatives at step A3. The Panel agrees with the application of the Procedure as performed by the JECFA for 10 of the 11 substances. For the remaining substance [FL-no: 13.097] the Panel did not find that it could be metabolised to innocuous products and should accordingly be evaluated via the B-side of the Procedure scheme. A no observed adverse effect level (NOAEL) of 52 mg/kg body weight was derived from a 90-day study in rats and compared with an exposure estimate of 0.9 µg/ capita / per day for anhydrolinalool oxide a margin of safety of 3.5 × 106 was calculated. Accordingly, the Panel agrees with the JECFA conclusion ‘No safety concern at estimated level of intake as flavouring substances’ based on the maximised survey-derived daily intake (MSDI) approach. The specifications for the materials of commerce have also been considered and for all 11 substances, the information is adequate.
