   食品伙伴网讯  2024年4月10日,欧盟食品安全局就一种食品酶过氧化物酶(peroxidase)的安全性评价发布意见。
 
  据了解,这种食品酶是由转基因黑曲霉菌株MOX生产的,旨在用于加工乳制品以生产改良乳蛋白和生产植物基牛奶和奶制品类似物。
 
  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 peroxidase (phenolic donor: hydrogen-peroxide oxidoreductase, EC 1.11.1.7) is produced with the genetically modified Aspergillus niger strain MOX 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 one food manufacturing process. Subsequently, the applicant requested to extend its use to include an additional process. In this assessment, EFSA updated the safety evaluation of this food enzyme when used in a total of two food manufacturing processes: processing of dairy products for the production of modified milk proteins and the production of plant-based analogues of milk and milk products. The dietary exposure to the food enzyme–total organic solids (TOS) was estimated to be up to 0.091 mg TOS/kg body weight (bw) per day in European populations. Using the no observed adverse effect level previously reported (2162 mg TOS/kg bw per day), the Panel derived a margin of exposure (MoE) of at least 23,758. based on the data provided for the previous evaluation and the revised MoE, the Panel concluded that this food enzyme does not give rise to safety concerns under the revised intended conditions of use.
