     2023年7月6日,歐盟食品安全局就一種食品酶三酰甘油脂肪酶(triacylglycerol lipase)的安全性評價發布意見。 
  據了解,這種食品酶是由轉基因釀酒酵母菌株LALL-LI生產的,旨在用于烘焙過程中。
 
  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 triacylglycerol lipase (triacylglycerol acylhydrolase, EC 3.1.1.3) is produced with the genetically modified Saccharomyces cerevisiae strain LALL-LI by Lallemand Inc. The genetic modifications do not give rise to safety concerns. The food enzyme is free from viable cells of the production organism, but not from recombinant DNA. It is intended to be used in baking processes. Dietary exposure to the food enzyme–total organic solids (TOS) was estimated to be up to 0.42 mg TOS/kg body weight per day in European populations. The production strain of the food enzyme fulfils the requirements for the qualified presumption of safety (QPS) approach to safety assessment. Therefore, the Panel considered that toxicological tests are not needed for the assessment of this food enzyme. A search for the similarity of the amino acid sequence of the food enzyme to known allergens was made and no match was found. The Panel considered that, under the intended conditions of use, the risk of allergic reactions by dietary exposure cannot be excluded, but 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.
