欧盟评估L-组氨酸盐酸盐-水合物作为所有动物饲料添加剂的安全性和有效性_安全事件解读_专业解读_食品安全合规服务_食品伙伴罐�/title>

　　 食品伙伴网讯2020�?1�?0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L-组氨酸盐酸盐-水合物（L-histidine mo nohydrochloride monohydrate）作为所有动物饲料添加剂的安全性和有效性发表科学意见�

　　据条例，这种L-组氨酸盐酸盐-水合物由大肠杆菌（Escherichia coli ）菌株KCCM 80212发酵产生。经过评估，专家小组认为该添加剂对所有动物物种和环境是安全的。L-组氨酸盐酸盐-水合物被认为是非反刍动物物种必需氨基酸L-组氨酸的有效来源。为了使补充的L-组氨酸在反刍动物中的功效与在非反刍动物中一样有效，就需要防止瘤胃降解的保护措施、�/div>

　　Following a request from the European Commission, the Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) was asked to deliver a scientific opinion on l‐histidine mo nohydrochloride (HCl) mo nohydrate produced by fermentation using Escherichia coli KCCM 80212 when used as a nutritio nal additive in feed for all animal species. The production strain is genetically modified. The production strain and its recombinant DNA were not detected in the final product. l‐Histidine HCl mo nohydrate manufactured by fermentation using E. coli KCCM 80212 does not give rise to any safety co ncern regarding the genetic modification. The use of l‐histidine HCl mo nohydrate produced by fermentation using E. coli KCCM 80212 is safe for the target species when used as a nutritio nal additive to supplement the diet in appropriate amounts to cover the requirements, depending on the species, the physiological state of the animal, the performance level, the enviro nmental conditions, the background amino acid composition of the unsupplemented diet and the status of some essential trace elements such as copper and zinc. l‐Histidine HCl mo nohydrate produced using E. coli KCCM 80212 supplemented at levels appropriate for the requirements of the target species is co nsidered safe for the consumer. l‐Histidine HCl mo nohydrate produced by E. coli KCCM 80212 is a skin sensitiser. There is a risk for persons handling the additive from the exposure to endotoxins by inhalation. The additive under assessment is not irritant to skin or eyes. The use of l‐histidine HCl mo nohydrate produced using E. coli KCCM 80212 in animal nutrition is not expected to represent a risk to the environment. l‐Histidine HCl mo nohydrate is co nsidered an efficacious source of the essential amino acid l‐histidine for non‐ruminant animal species. For the supplemental l‐histidine to be as efficacious in ruminants as in non‐ruminant species, it would require protection against degradation in the rumen.
