　　 食品伙伴网讯2023�?�?日，欧盟食品安全局就一种D-塔格�?-差向异构酶（d-tagatose 3-epimerase）的安全性评价发布意见�

　　据了解，这种食品酶是由转基因大肠杆菌菌株PS-Sav-001生产的，旨在用于将d-果糖转化为特殊碳水化合物d-阿洛酮糖、�/div>

　　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，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隐患。部分原文报道如下：

　　The food enzyme d-tagatose 3-epimerase (EC 5.1.3.31) is produced with the genetically modified Escherichia coli strain PS-Sav-001 by SAVANNA Ingredients GmbH. The genetic modifications do not give rise to safety concerns. The food enzyme is co nsidered free from viable cells of the production organism and its DNA. The food enzyme is used while retained inside a membrane reactor to co nvert d-fructose into the speciality carbohydrate d-allulose (syn. d-psicose). Since residual amounts of total organic solids (TOS) are removed by the purification steps applied during the production of d-allulose, dietary exposure was not calculated and toxicological studies were not co nsidered 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 co nsidered that under the intended co nditions of use, the risk of allergic reactions by dietary exposure cannot be excluded, but the likelihood is low. ba sed on the data provided, the Panel co ncluded that this food enzyme does not give rise to safety co ncerns under the intended co nditions of use.
