食品伙伴網(wǎng)訊   據(jù)歐盟食品安全局（EFSA）消息，7月15日歐盟食品安全局就2,4,4'-三氟苯甲酮（2,4,4′-trifluorobenzophenone，TFB）用于食品接觸材料的安全性發(fā)布意見。

　　2,4,4'-三氟苯甲酮作為共聚單體用于生產(chǎn)聚醚醚酮樹脂（ Polyether Ether Ketone,PEEK）塑料。由PEEK塑料制成的成品用于接觸保質(zhì)期短的食品，包括高溫條件下的食品。經(jīng)過相關(guān)試驗發(fā)現(xiàn)，PEEK塑料用于食品接觸產(chǎn)品時，并未檢出2,4,4'-三氟苯甲酮。2,4,4'-三氟苯甲酮用于食品接觸材料的基因毒性并不構(gòu)成風險。

　　部分原文報道如下：

　　This scientific opinion of the EFSA Panel on Food Contact Materials, Enzymes, Flavourings and Processing Aids （CEF Panel） deals with the safety assessment of 2,4,4′-trifluorobenzophenone （TFB）， Chemical Abstracts Service （CAS） No 80512-44-3, Food Contact Materials （FCM） substance No 1061, for use as a co-monomer to manufacture polyether ether ketone （PEEK） plastics. The final articles made of PEEK are intended for repeated use in contact with all types of foods for short-term duration, including at high temperatures. In tests for migration from PEEK under exaggerated test conditions compared to the intended uses, TFB was not detected using a method with a limit of detection of food simulant. No TFB-related impurities, oligomers or reaction products were detected in the same set of migration tests. No oligomeric fraction below 1,000 Da was found in PEEK samples made without and with TFB used as a co-monomer. The substance was tested in three genotoxicity tests and was considered not to raise a concern for genotoxicity. Therefore, the CEF Panel concluded that TFB is not of safety concern for the consumer if used as co-monomer up to  （the highest tested concentration based on the final material） in the manufacture of PEEK plastics.
