The food enzyme thermolysin (EC. 3.4.24.27) is produced with the non-genetically modified strain AE-TP 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 eight food manufacturing processes. Subsequently, the applicant has requested to extend its use to one additional process, to withdraw two processes and to revise the use levels. In this assessment, EFSA updated the safety evaluation of this food enzyme for use in a total of seven food manufacturing processes. The dietary exposure to the food enzyme-total organic solids (TOS) was calculated to be up to 0.989 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 (700 mg TOS/kg bw per day, the mid-dose tested), the Panel derived a revised margin of exposure of at least 708. 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.
食品酶嗜热菌蛋白酶(EC. 3.4.24.27)由天野酶制剂公司使用非转基因菌株AE - TP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,该食品酶在八种食品制造工艺中使用时不会引发安全问题。随后,申请人请求将其使用范围扩展至另外一种工艺,撤回两种工艺并修订使用水平。在本次评估中,欧洲食品安全局更新了对这种食品酶在总共七种食品制造工艺中使用的安全性评估。经计算,欧洲人群通过膳食摄入该食品酶 - 总有机固体(TOS)的量最高可达每天0.989毫克TOS/千克体重(bw)。将这一数据与先前意见中报告的未观察到不良影响水平(每天700毫克TOS/千克bw,测试的中剂量)相结合,专家小组得出修订后的暴露边际至少为708。根据先前评估提供的数据以及本次评估中修订后的暴露边际,专家小组得出结论,在修订后的预期使用条件下,这种食品酶不会引发安全问题。
