食品添加剂网络新闻 据欧盟食品安全局介绍,2022年8月4日(EFSA)欧盟动物饲料添加剂及产品应欧盟委员会要求(FEEDAP)纤维素酶、β-对所有动物青贮饲料添加剂的安全性和有效性发表科学意见。
纤维素酶是由黑曲霉引起的CBS 120604生产的,β-由新黑曲霉组成的葡聚糖酶MUCL 39199年生产的木聚糖酶是橙绿木霉MUCL 39203和CBS 614.94生产。部分原文报道如下:
Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and the efficacy of the feed additives cellulase (produced by Aspergillus niger CBS 120604), beta-glucanase (produced by Aspergillus neoniger MUCL 39199) and xylanases (produced by Trichoderma citrinoviride MUCL 39203 and CBS 614.94) as silage additives for all animal species. In 2018, the FEEDAP Panel evaluated 11 enzymes to be used as silage additives. In that opinion, the additives, including the production strains, were characterised in full and their safety and efficacy were evaluated. However, the Panel could not conclude on the identification of the production strains of the xylanase produced by the strain with deposit number MUCL 39203 (product referred as to J) and the glucanase produced by strain with deposit number MUCL 39199 (product referred as to L). The Panel could not conclude either on the efficacy of the products J, L as well as for the cellulase produced by the strain with deposit number CBS 120604 (product referred as to H) and the xylanase produced by the strain with deposit number CBS 614.94 (product referred to as K). The newly submitted information showed that the species for the xylanase produced by the strain with deposit number MUCL 39203 (product J), should be changed into Trichoderma citrinoviride, and that the species of the production strain for the glucanase produced by the strain with deposit number MUCL 39199 (product L), should be changed into Aspergillus neoniger. The Panel concluded that the four additives have the potential to reduce the protein degradation during the ensiling process when added at the corresponding inclusion levels in different types of forages.
