2025年5月7日,欧盟食品安全局就一种食品酶乙酰乳酸脱羧酶(acetolactate decarboxylase)的安全性评价发布意见。
据了解,这种食品酶是由转基因枯草芽孢杆菌菌株DP-Ezz65生产的,旨在用于谷物和其他谷物的加工,以生产酿造产品。
经过评估,专家小组认为,在预期的使用条件下,不能排除通过饮食接触引起过敏反应的风险,但这种情况发生的可能性很低。根据所提供的数据,小组得出结论,该食品酶在预期的使用条件下不会引起安全问题。部分原文报道如下:
The food enzyme acetolactate decarboxylase (α-acetolactate decarboxylase; EC 4.1.1.5) is produced with the genetically modified Bacillus subtilis strain DP-Ezz65 by Genencor International B.V. The genetic modifications do not give rise to safety concerns. The production strain meets the requirements for the qualified presumption of safety (QPS) approach. The food enzyme was considered free from viable cells of the production organism and its DNA. It is intended to be used in the processing of cereals and other grains for the production of brewed products. Dietary exposure was estimated to be up to 0.001 mg total organic solids/kg body weight per day in European populations. Given the QPS status of the production strain and the absence of concerns resulting from the food enzyme manufacturing process, toxicity tests were considered unnecessary by the Panel. A search for the homology of the amino acid sequence of the acetolactate decarboxylase to known allergens was made and no match was found. The Panel considered that a risk of allergic reactions upon dietary exposure to the food enzyme cannot be excluded, but that the likelihood is low. based on the data provided, the Panel concluded that this food enzyme does not give rise to safety concerns, under the intended conditions of use.
