據(jù)了解，這種食品酶是由非轉(zhuǎn)基因葉片微桿菌菌株SYG27B生產(chǎn)的，旨在用于果糖的異構(gòu)化生產(chǎn)特殊碳水化合物D-阿洛酮糖。

 

　　經(jīng)過(guò)評(píng)估，由于無(wú)法進(jìn)行危害識(shí)別和定性，也無(wú)法確定生產(chǎn)微生物的身份，專家小組無(wú)法對(duì)該酶的安全性得出結(jié)論。部分原文報(bào)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.
