   食品伙伴网讯  2026年7月2日,欧盟食品安全局就一种食品酶三酰甘油脂肪酶(triacylglycerol lipase)的安全性评价发布意见。
 
  据了解,这种食品酶是由转基因里氏木霉菌株DP-Nzk118生产的,旨在用于谷物和其他谷物的加工,以生产蒸馏酒精。
 
  经过评估,专家小组得出结论,该食品酶在预期的使用条件下不会引起安全问题。部分原文报道如下:
 
  The food enzyme triacylglycerol lipase (triacylglycerol acylhydrolase, EC 3.1.1.3) is produced with the genetically modified Trichoderma reesei strain DP-Nzk118 by Genencor International B.V. The genetic modifications do not give rise to safety concerns. The food enzyme was considered free from viable cells of the production organism and its DNA. It is intended to be used in the processing of cereals and other grains for the production of distilled alcohol. Since residual amounts of food enzyme–total organic solids are removed in the food manufacturing process, dietary exposure estimation and toxicity testing were considered unnecessary. A search for the homology of the amino acid sequence of the triacylglycerol lipase to known allergens was made and no match was found. The Panel considered that a risk of allergic reactions upon dietary exposure to the food enzyme can be excluded when used for the production of distilled alcohol. 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.
