欧盟评估非转基因解淀粉芽胞杆菌菌株DP-Cyb74生产的枯草杆菌金属蛋白酶的安全性

 

　　据了解，这种食品酶是由非转基因解淀粉芽胞杆菌菌株DP-Cyb74生产的，旨在用于6种食品制造过程。

 

　　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 bacillolysin (EC 3.4.24.28) is produced with the non-genetically modified Bacillus amyloliquefaciens strain DP-Cyb74 by Genencor International B.V. The production strain met all requirements for the qualified presumption of safety (QPS) approach to safety assessment. The food enzyme is intended to be used in six food manufacturing processes. Dietary exposure to the food enzyme total organic solids (TOS) was estimated to be up to 1.536 mg TOS/kg body weight per day in European populations. As the production strain qualifies for the QPS approach and no issue of concern arose from the production process of the food enzyme, the Panel considered that no toxicological studies other than the assessment of allergenicity were necessary. A search for the similarity of the amino acid sequence of the food enzyme to known allergens was made and no match was found. The Panel considered that the risk of allergic reactions by dietary exposure cannot be excluded, but 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.
