2020年5月29日，欧盟食品安全局发布关于一种具有β-葡聚糖酶（β-lysophospholipase）和-β-木聚糖酶（β‐xylanase）活性的食品酶的安全性评估结果。
据了解，这种食品酶是由DuPont公司用非转基因里氏木霉（Trichoderma reesei）菌株DP ‐Nya67生产的。这种食品酶旨在用于酿造过程、生产淀粉和麸质的谷物处理以及蒸馏酒精生产中。经过评估，由于缺乏足够的成分数据，专家小组完成对这种食品酶安全性的评估。部分原文报道如下：
Since residual amounts of the food enzyme are removed by distillation and during grain treatment, dietary exposure was only calculated for brewing processes. based on the maximum recommended use levels for brewing processes, dietary exposure to the food enzyme–Total Organic Solids （TOS ） was estimated to be up to 4.585 mg TOS /kg body weight （bw） per day. Since the compositional data provided was insufficient to characterise the food enzyme batches used for toxicological testing, their suitability for use in the toxicological tests could not be established. As result, the toxicological studies provided were not further considered by the Panel. Similarities of the amino acid sequences to those of known allergens were searched and no matches were 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 to occur is considered to be low. In the absence of compositional data sufficient to characterise the food enzyme batches used for toxicological testing, the Panel is unable to complete its assessment of the safety of the food enzyme.
