  食物伙伴网讯  2019年11月20日,欧盟食物保险局EFSA)就食物酶木聚糖酶(1,4‐β‐d‐xylan xylanohydrolase)的保险性宣布科学看法。
 
  据懂得,这种食物酶是Advanced Enzyme Technologies Ltd.应用非转基因短小芽孢杆菌(Bacillus pumilus) BLXSC菌株出产的,旨在用于烘焙进程、用于出产淀粉和谷卵白级分的谷物处置及蒸馏酒精出产中。经由评价,评价小组得出论断,这种食物酶在预期应用条件下不会惹起保险成绩。局部原文报道如下:
 
  The food enzyme 1,4‐β‐d‐xylan xylanohydrolase (EC 3.2.1.8) is produced with the non‐genetically modified strain Bacillus pumilus (strain BLXSC) by Advanced Enzyme Technologies Ltd. The food enzyme is intended to be used in baking processes, grain treatment for the production of starch and gluten fractions, and distilled alcohol production. Since residual amounts of the food enzyme are removed by distillation and during grain treatment, dietary exposure was only calculated for baking processes. based on the maximum recommended use levels for baking processes, and individual data from the EFSA Comprehensive European Food Database, dietary exposure to the food enzyme-Total Organic Solids (TOS) was estimated to be up to 0.138 mg TOS/kg body weight (bw) per day. As the production strain of B. pumilus meets the requirements for a Qualified Presumption of Safety (QPS) approach, no toxicological data are required. Similarity of the amino acid sequence to those of known allergens was searched and no match was found. The Panel considered that under the intended conditions of use (other than distilled alcohol production), the risk of allergic sensitisation and elicitation reactions by dietary exposure cannot be excluded, but is considered to be low. based on the QPS status of the production strain and the data provided, the Panel concluded that this food enzyme does not give rise to safety concerns under the intended conditions of use.
