Abstract

The food enzyme triacylglycerol lipase (triacylglycerol acylhydrolase; EC 3.1.1.3) is produced with the non-genetically modified strain AE-L 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 one food manufacturing process. Subsequently, the applicant has requested to extend its use to include four additional processes and to revise the previous use level. In this assessment, EFSA updated the safety evaluation of this food enzyme when used in a total of five food manufacturing processes. The dietary exposure to the food enzyme-total organic solids (TOS) was calculated to be up to 0.458 mg TOS/kg body weight (bw) per day in European populations. When combined with the no observed adverse effect level previously reported (1726 mg TOS/kg bw per day, the highest dose tested), the Panel derived a revised margin of exposure of at least 3769. 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.

摘要

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菌株AE-L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,该食品酶在一种食品制造工艺中使用时不会引起安全问题。随后,申请人请求将其使用范围扩大到另外四种工艺,并修订先前的使用水平。在本次评估中,EFSA更新了该食品酶在总共五种食品制造工艺中使用时的安全性评估。据计算,欧洲人群通过膳食摄入该食品酶的总有机固体(TOS)量最高可达每天0.458毫克TOS/千克体重(bw)。将这一数值与先前报告的未观察到不良反应水平(每天1726毫克TOS/千克bw,为测试的最高剂量)相结合,专家小组得出修订后的暴露边际至少为3769。根据先前评估提供的数据以及本次评估修订后的暴露边际,专家小组得出结论,在修订后的预期使用条件下,这种食品酶不会引起安全问题。
