欧盟评估非转基因解淀粉芽孢杆菌菌株GNP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孢杆菌菌株GNP生产的，旨在用于九种食品生产过程:加工谷物和其他谷物以生产焙烤产品、除焙烤、酿造产品和蒸馏酒精以外的谷物基产品；用于生产调味制剂和改良乳蛋白的乳制品加工；加工肉类和鱼类产品以生产蛋白质水解产物；加工源自植物和真菌的产品，用于生产蛋白水解产物和基于植物的牛奶和奶制品类似物。

 

　　经过评估，专家小组认为，在预期的使用条件下（蒸馏酒精生产除外），不能排除饮食暴露引起过敏反应的风险，但这种可能性被认为很低。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 bacillolysin (EC 3.4.24.28) is produced with the non-genetically modified Bacillus amyloliquefaciens strain GNP by DSM Food Specialties B.V. The production strain qualifies for the qualified presumption of safety (QPS) approach to safety assessment. The food enzyme is intended to be used in nine food manufacturing processes: processing of cereals and other grains for the production of baked products, cereal-based products other than baked, brewed products and distilled alcohol; processing of dairy products for the production of flavouring preparation and modified milk proteins; processing of meat and fish products for the production of protein hydrolysates; processing of plant- and fungal-derived products for the production of protein hydrolysates and plant-based analogues of milk and milk products. Since the food enzyme–total organic solids (TOS) is not carried into distilled alcohols, dietary exposure was estimated only to the remaining eight food processes. Exposure was estimated to be up to 17.934 mg TOS/kg body weight per day in European populations. As the production strain qualifies for the QPS approach to safety assessment and no issue of concern arose from the production process, no toxicological studies other than the assessment of allergenicity were required. 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 upon dietary exposure cannot be excluded (except for distilled alcohol production), 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.
