欧盟评估一种6-植酸酶作为有鳍鱼类饲料添加剂的安全性和有效性

 

　　据了解，这种6-植酸酶是由里氏木霉CBS 126897生产的。经过评估，专家小组认为在建议的使用条件下该添加剂对目标物种和环境是安全的。该添加剂在500 FTU/千克全价饲料的使用水平下对鲑鱼和观赏鱼是有效的，在2500 FTU/千克全价饲料的使用水平下对其他有鳍鱼类是有效的。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 efficacy of 6-phytase (Quantum® Blue) as a zootechnical feed additive for fin fish. The additive is authorised for use in poultry and pigs. The additive is available in solid and liquid forms, and the 6-phytase contained in the product is produced by fermentation with a genetically modified strain of Trichoderma reesei. The Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) concluded that the genetic modification of the production strain does not give rise to safety concerns; viable cells of the production strain and its DNA were not detected in the final products. The FEEDAP Panel concluded that, based on the data available, the additive tested is safe for fin fish at the highest recommended level of 2500 phytase activity unit (FTU)/kg complete feed. The Panel concluded that Quantum® Blue is not an irritant to skin and eyes nor a skin sensitiser. Owing to the proteinaceous nature of the active substance, 6-phytase (Quantum® Blue) is considered a respiratory sensitiser. The use of Quantum® Blue as a feed additive is considered safe for the environment. The additive is considered to be efficacious as a zootechnical additive for salmonids and ornamental fish at 500 FTU/kg complete feed and other fin fish at 2500 FTU/kg complete feed.
