2026年7月6日，欧盟食品安全局就一种食品酶内切-1,4-β-木聚糖酶（endo-1,4-β-xylanase）的安全性评价发布意见。
据了解，这种食品酶是由转基因米曲霉菌株NZYM-FB生产的，旨在用于六种食品生产过程。
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 endo 1,4-β-xylanase (4-β-d-xylan xylanohydrolase, EC 3.2.1.8) is produced with the genetically modified Aspergillus oryzae strain NZYM-FB by Novozymes A/S. The safety of this food enzyme was evaluated previously and it did not give rise to safety concerns when used in five food manufacturing processes. Subsequently, the applicant has requested to extend its use to include one additional process. In this assessment, EFSA updated the safety evaluation of this food enzyme when used in a total of six food manufacturing processes. As the food enzyme–Total Organic Solids (TOS) are removed in two processes, the dietary exposure to the food enzyme–TOS was estimated for the remaining four food manufacturing processes. It was estimated to be up to 0.390 mg TOS/kg body weight (bw) per day in European populations. When combined with the no observed adverse effect level previously reported (106 mg TOS/kg bw per day), the Panel derived a margin of exposure of at least 272. based on the revised exposure estimation, the newly derived 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.
