2025年6月18日,歐盟食品安全局就一種果糖基轉移酶(fructosyltransferase)的安全性評價發布意見。
據了解,這種食品酶是由轉基因解脂耶氏酵母菌株E4772生產的,旨在用于生產低聚果糖的糖加工中。
經過評估,專家小組認為,在預期的使用條件下,不能排除飲食暴露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,評估小組得出結論,這種食品酶在預期使用條件下不會引起安全問題。部分原文報道如下:
The food enzyme sucrose:sucrose fructosyltransferase (sucrose:sucrose 1′-β-d-fructosyltransferase; EC 2.4.1.99) is produced with the genetically modified Yarrowia lipolytica strain E4772 by SEQENS. The production strain met the requirements for the qualified presumption of safety (QPS) approach. The food enzyme is free from viable cells of the production organism, but not free from recombinant DNA. The food enzyme is intended to be used in the processing of sugars for the production of fructo-oligosaccharides. The dietary exposure to the food enzyme–total organic solids (TOS) was estimated to be up to 0.088 mg TOS/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 sucrose: sucrose fructosyltransferase 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.
