据了解，这种食品酶是由非转基因叶片微杆菌菌株SYG27B生产的，旨在用于果糖的异构化生产特殊碳水化合物D-阿洛酮糖。

 

　　经过评估，由于无法进行危害识别和定性，也无法确定生产微生物的身份，专家小组无法对该酶的安全性得出结论。部分原文报道如下：

 

　　This assessment addresses a food enzyme preparation consisting of the immobilised non-viable cells of the non-genetically modified bacterium identified by the applicant (Samyang Corporation) as Microbacterium foliorum strain SYG27B. This strain produces the enzyme D-psicose 3-epimerase (EC 5.1.3.30). The food enzyme preparation is used for the isomerisation of fructose to produce the speciality carbohydrate D-allulose (synonym D-psicose). Since the hazard identification and characterisation could not be made and the identity of the production organism could not be established, the Panel was unable to complete the assessment of this food enzyme preparation containing D-psicose 3-epimerase.
