食品伙伴网讯   据欧盟食品安全局（EFSA）消息，7月15日欧盟食品安全局就2,4,4'-三氟苯甲酮（2,4,4′-trifluorobenzophenone，TFB）用于食品接触材料的安全性发布意见。

　　2,4,4'-三氟苯甲酮作为共聚单体用于生产聚醚醚酮树脂（ Polyether Ether Ketone,PEEK）塑料。由PEEK塑料制成的成品用于接触保质期短的食品，包括高温条件下的食品。经过相关试验发现，PEEK塑料用于食品接触产品时，并未检出2,4,4'-三氟苯甲酮。2,4,4'-三氟苯甲酮用于食品接触材料的基因毒性并不构成风险。

　　部分原文报道如下：

　　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.
