2025年5月7日，歐盟食品安全局就一種食品酶乙酰乳酸脫羧酶（acetolactate decarboxylase）的安全性評價發(fā)布意見。
據了解，這種食品酶是由轉基因枯草芽孢桿菌菌株DP-Ezz65生產的，旨在用于谷物和其他谷物的加工，以生產釀造產品。
經過評估，專家小組認為，在預期的使用條件下，不能排除通過飲食接觸引起過敏反應的風險，但這種情況發(fā)生的可能性很低。根據所提供的數據，小組得出結論，該食品酶在預期的使用條件下不會引起安全問題。部分原文報道如下：
The food enzyme acetolactate decarboxylase (α-acetolactate decarboxylase; EC 4.1.1.5) is produced with the genetically modified Bacillus subtilis strain DP-Ezz65 by Genencor International B.V. The genetic modifications do not give rise to safety concerns. The production strain meets the requirements for the qualified presumption of safety (QPS) approach. 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 brewed products. Dietary exposure was estimated to be up to 0.001 mg total organic solids/kg body weight per day in European populations. Given the QPS status of the production strain and the absence of concerns resulting from the food enzyme manufacturing process, toxicity tests were considered unnecessary by the Panel. A search for the homology of the amino acid sequence of the acetolactate decarboxylase 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 cannot be excluded, but that the likelihood is low. 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.
