欧盟评估扩展使用非转基因塔宾曲霉菌株ARF生产的非还原端α-l-阿拉伯呋喃糖苷酶的安全性

　　

　　据了解，这种食品酶是由非转基因塔宾曲霉菌株ARF生产的，旨在用于7种食品生产过程。

　　

　　经过评估，专家小组得出结论，这种食品酶在预期使用条件下不会引起安全问题。部分原文报道如下：

　　

　　The food enzyme non-reducing end α-l-arabinofuranosidase (α-l-arabinofura-noside non-reducing end α-l-arabinofuranosidase, EC 3.2.1.55) is produced with the non-genetically modified Aspergillus tubingensis strain ARF by DSM Food Specialties B.V. A safety evaluation of this food enzyme was made previously, in which EFSA concluded that this food enzyme did not give rise to safety concerns when used in five food manufacturing processes. Subsequently, the applicant requested to extend its use to include two additional processes. In this assessment, EFSA updated the safety evaluation of this food enzyme when used in a total of seven food manufacturing processes. The dietary exposure was calculated to be up to 0.458 mg total organic solids (TOS)/kg body weight (bw) per day in European populations. When combined with the no observed adverse effect level previously reported (234 mg TOS/kg bw per day, the highest dose tested), the Panel derived a margin of exposure of at least 511. based on the new data, the revised margin of exposure and the previous evaluation, the Panel concluded that this food enzyme does not give rise to safety concerns under the revised intended conditions of use.
