欧盟评估非转基因百岁兰曲霉菌株NZYM-KF生产的菊粉酶的安全性

 

　　据了解，这种食品酶是由非转基因百岁兰曲霉菌株NZYM-KF生产的，旨在用于果糖多糖的加工中，以生产低聚果糖。

 

　　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，特别是对番茄过敏的人，但这种风险不会超过食用番茄的风险。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 inulinase (1-β-d-fructan fructanohydrolase; EC 3.2.1.7) is produced with the non-genetically modified Aspergillus welwitschiae strain NZYM-KF by Novozymes A/S. The food enzyme is free from viable cells of the production organism. It is intended to be used in the processing of fructo-polysaccharides for the production of fructo-oligosaccharides. Since residual amounts of total organic solids (TOS) are removed during the food manufacturing process, toxicological studies other than allergenicity were considered unnecessary and dietary exposure was not calculated. A search for the similarity of the amino acid sequence of the food enzyme to known allergens was made and two matches with tomato allergens were found. The Panel considered that the risk of allergic reactions upon dietary exposure to this food enzyme, particularly in individuals sensitised to tomato, cannot be excluded, but is expected not to exceed that of tomato. As the prevalence of allergic reactions to tomato is low, also the likelihood of such reactions to occur to the food enzyme 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.
