2019年5月2日，据欧盟食品安全局（EFSA）消息，应欧盟委员会的要求，欧盟动物饲料添加剂和产品（FEEDAP）研究小组就大肠杆菌KCCM 80152发酵产生的L-色氨酸（L-tryptophan）作为所有动物品种饲料和饮用水的营养添加剂发表科学意见。 经过评估，小组认为，这种添加剂对非反刍动物目标物种以及动物产品消费者是安全的。 部分原文报道如下： 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‐tryptophan produced by fermentation using Escherichia coli KCCM 80152 when used as nutritional additive in feed and water for drinking for all animal species. The production strain and its recombinant DNA were not detected in the additive. l‐Tryptophan, manufactured by fermentation with E. coli KCCM 80152, does not give rise to any safety concern with regard to the genetic modification of the production strain. The use of l‐tryptophan produced using E. coli KCCM 80152 in supplementing feed to compensate for tryptophan deficiency in feedingstuffs is safe for non‐ruminant target species. Using unprotected forms of tryptophan in ruminants can be a risk. 本文由食品资讯中心编辑，供网友参考，欢迎转载，转载请注明出处！有任何疑问，请联系news@foodmate.net。
