食品伙伴網訊  據歐盟食品安全局（EFSA）消息，2019年7月25日，歐盟食品安全局就來自轉基因里氏木霉菌株DP‐Nzs51的海藻糖酶（α，α‐海藻糖酶葡萄糖水解酶，EC 3.2.1.28）（ trehalase （α，α‐trehalase glucohydrolase, EC 3.2.1.28）的安全性評價發(fā)布意見。

 

　　據了解，里氏木霉菌株DP‐Nzs51產生的海藻糖酶旨在用于蒸餾酒精生產中。經過評估，評估小組認為在預期使用條件下這種食品酶不會引起安全問題。

 

　　部分原文報道如下：

 

　　The food enzyme trehalase （α，α‐trehalase glucohydrolase, EC 3.2.1.28） is produced with a genetically modified Trichoderma reesei DP‐Nzs51 by Danisco US Inc. The genetic modifications do not give rise to safety concerns. The food enzyme is free from viable cells of the production organism and recombinant DNA. The trehalase is intended to be used in distilled alcohol production. Since residual amounts of total organic solids are removed by distillation （> 99%）， toxicological data were not considered necessary and dietary exposure was not calculated. Similarity of the amino acid sequence to those of known allergens was searched and no matches were found. The Panel considered that, under the intended conditions of use, the risk of allergic sensitisation and elicitation reactions by dietary exposure can be excluded. 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.
