据了解，这种食品酶是由 非转基因长野解普鲁兰杆菌（Pullulanibacillus naganoensis)菌株AE-PL生产的，旨在用于8种食品生产过程。

　　经过评估，专家小组得出结论，这种食品酶在预期使用条件下不会引起安全问题。部分原文报道如下：

　　The food enzyme pullulanase (pullulan 6-α-glucanohydrolase; EC 3.2.1.41) is produced with the non-genetically modified Pullulanibacillus naganoensis strain AE-PL by Amano Enzyme Inc. A safety e valuation of this food enzyme was made previously, in which EFSA co ncluded that this food enzyme did not give rise to safety co ncerns when used in one food manufacturing process. Subsequently, the applicant has requested to extend its use to include seven additio nal processes and to revise the previous use level. In this assessment, EFSA updated the safety e valuation of this food enzyme when used in a total of eight food manufacturing processes. As the food enzyme-total organic solids (TOS) are not carried into the final foods in two food manufacturing processes, the dietary exposure was estimated o nly for the remaining six processes. The dietary exposure was calculated to be up to 0.004 mg TOS/kg body weight (bw) per day in European populations. The Panel e valuated the repeated dose 90-day oral toxicity study in rats submitted in the previous application and identified a no observed adverse effect level of 643 mg TOS/kg bw per day, the highest dose tested. When compared with the calculated dietary exposure, this resulted in a margin of exposure of at least 160,750. ba sed on the data provided for the previous e valuation and the revised margin of exposure in the present e valuation, the Panel co ncluded that this food enzyme does not give rise to safety co ncerns under the revised intended co nditions of use.
