摘要

三酰基甘油脂肪酶(三酰基甘油酰基水解酶;EC 3.1.1.3)是用转基因法菲Komagataella phaffii菌株DSM 34125生产的。汉森。基因改造不会引起安全问题。食用酶被认为不含生产生物体的活细胞及其DNA。该食品酶计划用于四种食品生产过程。据估计,在欧洲人群中,每天的饮食暴露量高达0.039 mg总有机固体(TOS)/kg体重。鉴于生产菌株安全状况的有条件推定和食品酶制造过程中不存在引起关注的问题,评估小组认为没有必要进行毒性测试。对三酰甘油脂肪酶的氨基酸序列与已知过敏原的同源性进行了搜索,没有发现匹配。专家小组认为不能排除饮食接触引起过敏反应的风险,但可能性很低。根据所提供的数据,小组得出结论,在预期的使用条件下,这种食品酶不会引起安全问题。

Safety evaluation of the food enzyme triacylglycerol lipase from the genetically modified Komagataella phaffii strain DSM 34125

The food enzyme triacylglycerol lipase (triacylglycerol acylhydrolase; EC 3.1.1.3) is produced with the genetically modified Komagataella phaffii strain DSM 34125 by Chr. Hansen. The genetic modifications do not give rise to safety concerns. The food enzyme was considered free from viable cells of the production organism and its DNA. The food enzyme is intended to be used in four food manufacturing processes. Dietary exposure was estimated to be up to 0.039 mg total organic solids (TOS)/kg body weight per day in European populations. Given the qualified presumption of safety status of the production strain and the absence of concerns resulting from the food enzyme manufacturing process, toxicity tests were considered unnecessary by the Panel. A search for the homology of the amino acid sequence of the triacylglycerol lipase to known allergens was made and no match was found. The Panel considered that a risk of allergic reactions upon dietary exposure cannot be excluded, but that 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.
