   食品伙伴网讯  2023年11月30日,欧盟食品安全局就一种食品酶枯草杆菌金属蛋白酶(bacillolysin)的安全性评价发布意见。
 
  据了解,这种食品酶是由非转基因解淀粉芽孢杆菌菌株AGS 430生产的,旨在用于11种食品生产过程:加工谷物和其他谷物以生产焙烤产品;烘焙以外的谷物制品;酿造产品;淀粉和面筋部分;蒸馏酒精;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,以生产蛋白水解物和基于植物的牛奶和奶制品类似物;酵母和酵母产品加工。
 
  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 AGS 430 by Kerry Ingredients & Flavours Ltd. The production strain qualifies for the qualified presumption of safety (QPS) approach to safety assessment. The food enzyme is intended to be used in 11 food manufacturing processes: processing of cereals and other grains for the production of baked products; cereal-based products other than baked; brewed products; starch and gluten fractions; distilled alcohol; processing of dairy products for the production of flavouring preparations 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; processing of yeast and yeast products. Since residual amounts of the total organic solids (TOS) are removed during two processes, dietary exposure was estimated only for the remaining nine food manufacturing processes. Exposure was estimated up to 3.482 mg TOS/kg body weight (bw) 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 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.
