The food enzyme triacylglycerol lipase (triacylglycerol acylhydrolase; EC 3.1.1.3) is produced with the non-genetically modified s strain AE-TL(B) by Amano Enzyme Inc. A safety evaluation of this food enzyme was made previously, in which EFSA concluded that this food enzyme did not give rise to safety concerns when used in two food manufacturing processes. Subsequently, the applicant requested to extend its use to include four additional processes and to revise the use levels. In this assessment, EFSA updated the safety evaluation of this food enzyme when used in a total of six food manufacturing processes. As the food enzyme-total organic solids (TOS) are removed from one food manufacturing process, the dietary exposure to the food enzyme-TOS was estimated only for the remaining five processes. Dietary exposure was calculated to be up to 0.086 mg TOS/kg body weight (bw) per day in European populations. When combined with the no observed adverse effect level reported in the previous opinion (1960 mg TOS/kg bw per day, the highest dose tested), the Panel derived a margin of exposure of at least 22,791. Based on the data provided for the previous evaluation and the revised margin of exposure in the present evaluation, the Panel concluded that this food enzyme does not give rise to safety concerns under the revised intended conditions of use.
食品酶三酰甘油脂肪酶(三酰甘油酰基水解酶;EC 3.1.1.3)由天野酶制剂公司使用非转基因s菌株AE-TL(B)生产。此前已对这种食品酶进行了安全性评估,欧洲食品安全局(EFSA)得出结论,在两种食品制造工艺中使用这种食品酶不会引发安全问题。随后,申请人请求将其使用范围扩大至另外四种工艺,并修订使用水平。在本次评估中,EFSA更新了这种食品酶在总共六种食品制造工艺中使用时的安全性评估。由于在一种食品制造工艺中会去除食品酶中的总有机固体(TOS),因此仅对其余五种工艺估计了膳食中食品酶-TOS的暴露量。经计算,欧洲人群膳食中食品酶-TOS的暴露量高达每天0.086毫克TOS/千克体重(bw)。将此暴露量与之前意见中报告的未观察到不良反应水平(每天1960毫克TOS/千克bw,为测试的最高剂量)相结合,专家小组得出的暴露量边际至少为22791。基于先前评估提供的数据以及本次评估中修订后的暴露量边际,专家小组得出结论,在修订后的预期使用条件下,这种食品酶不会引发安全问题。
