    2023年1月19日，欧盟食品安全局就一种食品酶三酰甘油脂肪酶（triacylglycerol lipase）的安全性评价发布意见。

据了解，这种食品酶是由非转基因卷枝毛霉菌株AE-LMH生产的，旨在用于烘焙过程、鸡蛋加工和酶改性乳制品配料的生产中。

经过评估，专家小组认为，在预期的使用条件下，不能排除通过饮食接触引起过敏反应的风险，但这种情况发生的可能性很低。根据所提供的数据，小组得出结论，该食品酶在预期的使用条件下不会引起安全问题。部分原文报道如下：

The food enzyme triacylglycerol lipase (triacylglycerol acylhydrolase; EC 3.1.1.3) is produced with the non-genetically modified Mucor circinelloides strain AE-LMH by Amano Enzyme Inc. The food enzyme is considered free from viable cells of the production organism. The food enzyme is intended to be used in baking processes, egg processing and the manufacture of enzyme-modified dairy ingredients (EMDI). Dietary exposure to the food enzyme–total organic solids (TOS) was estimated to be up to 0.242 mg TOS/kg body weight (bw) per day in European populations. Genotoxicity tests did not raise a safety concern. The systemic toxicity was assessed by means of a repeated dose 90-day oral toxicity study in rats. The Panel identified a no observed adverse effect level of 784 mg TOS/kg bw per day, the highest dose tested, which when compared with the estimated dietary exposure, results in a margin of exposure of at least 3,240. 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 of such reactions 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.
