核心提示:2023年1月11日,据欧盟食品安全局(EFSA)消息,应欧盟委员会要求,欧盟动物饲料添加剂和产品(FEEDAP)研究小组就一种6-植酸酶(6-phytase)作为家禽、育肥猪、断奶仔猪和母猪饲料添加剂的安全性和有效性发表科学意见。
   食品伙伴网讯  2023年1月11日,据欧盟食品安全局EFSA)消息,应欧盟委员会要求,欧盟动物饲料添加剂和产品(FEEDAP)研究小组就一种6-植酸酶(6-phytase)作为家禽、育肥猪、断奶仔猪和母猪饲料添加剂的安全性和有效性发表科学意见。
 
  据了解,这种6-植酸酶由米曲霉DSM 33699产生。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。在500 FYT/千克全价饲料下,该添加剂可能对家禽、育肥猪、断奶仔猪和母猪有效。部分原文报道如下:
 
  The additive RONOZYME® Hiphos (GT/L) contains 6-phytase produced with a genetically modified strain of the filamentous fungus Aspergillus oryzae, it is currently authorised for poultry, pigs for fattening, weaned piglets and sows. The applicant has requested to change the production strain, substituting strain A. oryzae DSM 22594 for A. oryzae DSM 33699. RONOZYME® Hiphos (GT/L), manufactured with the production strain A. oryzae DSM 33699, did not give rise to safety concerns with regard to the genetic modification of the production strain. No viable cells of the production strain nor its recombinant DNA were detected in an intermediate product representative of both final forms of the additive. RONOZYME® Hiphos (GT/L) was considered safe for poultry, pigs for fattening, weaned piglets and sows at the recommended inclusion levels of 500–4,000 FYT/kg complete feed. The use of RONOZYME® Hiphos GT and L manufactured with the production strain A. oryzae DSM 33699 raised no concerns for consumers. In the absence of data on the final formulations, the Panel could not conclude on the potential of the additive to be irritant to eyes or skin, or a skin sensitiser. Due to the proteinaceous nature of the active substance, the additive was considered a respiratory sensitiser. The additive manufactured by A. oryzae DSM 33699 raises no safety concerns for the environment. The additive has the potential to be efficacious in poultry, pigs for fattening, weaned piglets and sows at 500 FYT/kg complete feed.
