2021年1月19日，歐盟食品安全局就一種食品酶交替糖蔗糖酶（alternansucrase ）的安全性評價發布意見。
據了解，這種食品酶是由檸檬明串珠菌NZYM‐DB生產的，旨在用于生產作為甜味劑的α-d-葡聚糖低聚糖。
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的過敏性致敏和誘發反應的風險，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 alternansucrase (sucrose:1,6(1,3)‐α‐d‐glucan 6(3)‐α‐d‐glucosyltransferase, EC 2.4.1.140) is produced with a non‐genetically modified Leuconostoc citreum strain NRRL B‐30894 by Cargill Incorporated. As a consequence of the absence of antimicrobial resistance genes identified in its genome, the production strain meets the criteria to qualify for the Qualified Presumption of Safety (QPS) approach to safety assessment. As no other concerns arising from the microbial source or from the manufacturing process have been identified, the Panel considers that toxicological tests are not needed for the assessment of this food enzyme. The alternansucrase food enzyme is intended to be used for the manufacture of α‐d‐glucan oligosaccharides as a sweetening agent. The purification processes applied to syrups produced from sucrose with alternansucrase are expected to largely remove the food enzyme. Any residual TOS remaining in the final product would consist of non‐hazardous material. This is based on the QPS status of the production organism, the medium components and the identified material used in downstream processing. Consequently, the Panel decided that dietary exposure did not need to be calculated. Similarity of the amino acid sequence to those of known allergens was searched and no match was found. The Panel considered that, under the intended conditions of use, the risk of allergic sensitisation and elicitation reactions by dietary exposure cannot be excluded, but the likelihood for this to occur is considered to be 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.
