2024年4月10日，歐盟食品安全局就一種腺苷酸脫氨酶（AMP deaminase）的安全性評價發(fā)布意見。
據(jù)了解，這種食品酶是由非轉(zhuǎn)基因曲霉菌株DEA 56-111生產(chǎn)的，旨在用于酵母和酵母產(chǎn)品的加工。
經(jīng)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(yīng)的風險，但這種可能性被認為很低。根據(jù)所提供的數(shù)據(jù)，評估小組得出結(jié)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 AMP deaminase (AMP aminohydrolase; EC 3.5.4.6) is produced with the non-genetically modified microorganism Aspergillus sp. strain DEA 56-111 by Shin Nihon Chemical Co., Ltd. The food enzyme was considered free from viable cells of the production organism. It is intended to be used in the processing of yeast and yeast products. Dietary exposure to the food enzyme-total organic solids (TOS) was estimated to be up to 0.005 mg TOS/kg body weight (bw) per day in European populations. Genotoxicity tests did not indicate a safety concern. The Panel identified a no observed adverse effect level of 1984 mg TOS/kg bw per day, the highest dose tested, which, when compared with the estimated dietary exposure, resulted in a margin of exposure of at least 396,800. 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 the risk of allergic reactions upon 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.
