The food enzyme pectinesterase (pectin pectylhydrolase; EC 3.1.1.11) is produced with the genetically modified strain AR-962 by AB Enzymes GmbH. 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 five food manufacturing processes. Subsequently, the applicant requested to extend its use to two additional processes. In this assessment, EFSA updated the safety evaluation of this food enzyme for uses in a total of seven food manufacturing processes. As the food enzyme-total organic solids (TOS) is removed from the final foods in three food manufacturing processes, the dietary exposure to the food enzyme-TOS was estimated only for the remaining four processes. Dietary exposure was up to 0.575 mg TOS/kg body weight (bw) per day in European populations. When combined with the NOAEL reported in the previous opinion (1000 mg TOS/kg bw per day, the highest dose tested), the Panel derived a margin of exposure of at least 1739. Based on the data provided for the previous evaluation and the revised margin of exposure, the Panel concluded that this food enzyme does not give rise to safety concerns under the revised intended conditions of use.
食品酶果胶酯酶(果胶果胶水解酶;EC 3.1.1.11)由AB Enzymes GmbH公司的转基因菌株AR-962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,该食品酶在五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大到另外两种工艺。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。由于在三种食品制造工艺中食品酶总有机固体(TOS)会从最终食品中去除,因此仅对其余四种工艺估计了膳食中食品酶-TOS的暴露量。欧洲人群膳食中食品酶-TOS的暴露量高达每天0.575毫克TOS/千克体重(bw)。将其与先前意见中报告的无观察到有害作用水平(NOAEL,每天1000毫克TOS/千克bw,测试的最高剂量)相结合,专家小组得出的暴露边际至少为1739。根据先前评估提供的数据和修订后的暴露边际,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。
