食品伙伴網(wǎng)訊  2020年2月18日，據(jù)歐盟食品安全局（EFSA）消息，應(yīng)歐盟委員會(huì)的要求，歐盟動(dòng)物飼料添加劑和產(chǎn)品（FEEDAP）研究小組就谷氨酸棒桿菌KCCM 80189發(fā)酵產(chǎn)生的異亮氨酸（L-Isoleucine）作為所有動(dòng)物品種飼料和飲用水的營(yíng)養(yǎng)添加劑發(fā)表科學(xué)意見(jiàn)。

 

　　經(jīng)過(guò)評(píng)估，此添加劑對(duì)目標(biāo)物種、消費(fèi)者和環(huán)境是安全的。部分原文報(bào)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 the safety and efficacy of l‐isoleucine produced by fermentation using Corynebacterium glutamicum KCCM 80189 when used as a nutritional additive in feed and water for drinking for all animal species. The production strain is not genetically modified. Viable cells of the production strain were not detected in the final additive. The additive does not give rise to any safety concern regarding the production strain. l‐Isoleucine produced using C. glutamicum KCCM 80189 is considered safe for the target species, for the consumer and for the environment. l‐Isoleucine produced by C. glutamicum KCCM 80189 is considered not toxic by inhalation, not irritant to skin or eyes and not a dermal sensitiser. Regarding the use in water, the FEEDAP Panel reiterates its concerns over the safety of l‐isoleucine administered simultaneously via water for drinking and feed owing to the risk of nutritional imbalances and hygienic reasons. l‐Isoleucine produced by C. glutamicum KCCM 80189 is considered as an efficacious source of the essential amino acid l‐isoleucine for non‐ruminant animal species. For the supplemental l‐isoleucine to be as efficacious in ruminants as in non‐ruminant species, it would require protection against degradation in the rumen.
