據了解，這種食品酶是由轉基因大腸桿菌菌株PS-Sav-001生產的，旨在用于將d-果糖轉化為特殊碳水化合物d-阿洛酮糖。

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，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隱患。部分原文報道如下：

The food enzyme d-tagatose 3-epimerase (EC 5.1.3.31) is produced with the genetically modified Escherichia coli strain PS-Sav-001 by SAVANNA Ingredients GmbH. The genetic modifications do not give rise to safety concerns. The food enzyme is considered free from viable cells of the production organism and its DNA. The food enzyme is used while retained inside a membrane reactor to convert d-fructose into the speciality carbohydrate d-allulose (syn. d-psicose). Since residual amounts of total organic solids (TOS) are removed by the purification steps applied during the production of d-allulose, dietary exposure was not calculated and toxicological studies were not considered necessary. 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.
