                   食品伙伴网听到讯  2022年7月6日,欧盟食品安全局就一种磷脂酶A1(phospholipase A1)的安全性评价发布意见。
                 
                  据了解,这种食品酶是由转基因米曲霉菌株NZYM-LJ生产的,旨在用ㄨ于烘焙过程。
                 
                  经过评估,专家小组认为,在预期的↘使用条件下,不能慢吞吞地开口说道排除饮食暴露引起过敏和诱发反应的风险,但〇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隐患№。部分原文报道如下:
                 
                  The food enzyme phospholipase A1 (phosphatidylcholine 1-acylhydrolase; EC 3.1.1.32) is produced with the genetically modified Aspergillus oryzae strain NZYM-LJ by Novozymes A/S. The genetic modifications do not give rise to safety concerns. The food enzyme is free from viable cells of the production organism and its DNA. The food enzyme is intended to be used in baking processes. Dietary exposure to the food enzyme–total organic solids (TOS) was estimated to be up to 0.09 mg TOS/kg body weight (bw) per day in European populations. Genotoxicity tests did not indicate 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 957.3 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 10,600. A search for similarity of the amino acid sequence of the food enzyme to known allergens was made and one 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 concludes that this food enzyme does not give rise to safety concerns under the intended conditions of use.
