欧盟评估非转基因解淀粉芽孢杆菌菌株AE-BAA生产的α-淀粉酶的安全性

　　

　　据了解，这种食品酶是由非转基因解淀粉芽孢杆菌菌株AE-BAA生产的，旨在用于八种食品生产过程。

　　

　　经过评估，专家小组认为，在预期的使用条件下，不能排除饮食暴露引起过敏反应的风险。根据所提供的数据，评估小组得出结论，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 α-amylase (4-α-d-glucan glucanohydrolase; EC 3.2.1.1) is produced with the non-genetically modified microorganism Bacillus amyloliquefaciens strain AE-BAA by Amano Enzyme Inc. The food enzyme is intended to be used in eight food manufacturing processes. Since residual amounts of food enzyme–total organic solids (TOS) are removed in two processes, dietary exposure was calculated only for the remaining six food manufacturing processes. It was estimated to be up to 0.842?mg TOS/kg body weight per day in European populations. The production strain of the food enzyme fulfils the requirements for the qualified presumption of safety (QPS) approach to safety assessment. Consequently, in the absence of other concerns, the Panel considered that toxicological studies were not needed for the safety assessment of this food enzyme. A search for the homology of the amino acid sequence of the food enzyme to known allergens was made and one match with a respiratory allergen was found. Known sources of food allergens were used in the manufacturing process, and the Panel considered that the risk of allergic reactions upon dietary exposure to this food enzyme cannot be excluded. 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.
