食品伙伴網(wǎng)訊  2019年5月3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）研究小組就大腸桿菌NITE BP‐02351發(fā)酵產(chǎn)生的L-亮氨酸（L-leucine）作為所有動(dòng)物品種飼料和飲用水的營養(yǎng)添加劑發(fā)表科學(xué)意見。

 

　　經(jīng)過評(píng)估，評(píng)估小組認(rèn)為當(dāng)用作所有動(dòng)物物種的調(diào)味化合物時(shí)，在25mg/Kg的建議使用水平下是安全的。在建議的使用條件下，這種添加劑被認(rèn)為是有效的飼料調(diào)味化合物。

 

　　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 l‐leucine produced by fermentation with Escherichia coli NITE BP‐02351 when used as nutritional additive or as feed flavouring compound in feed and water for drinking for all animal species. The product under assessment is l‐leucine produced by fermentation with a genetically modified strain of E. coli （NITE BP‐02351）。 The production strain and its recombinant DNA were not detected in the final products. l‐Leucine, manufactured by fermentation with E. coli NITE BP‐02351, does not give rise to any safety concern to the production strain. The use of l‐leucine produced with E. coli NITE BP‐02351 is safe for the target species when used to supplement the diet in appropriate amounts. It is safe at the proposed use level of 25 mg/kg when used as flavouring compound for all animal species. The use of l‐leucine produced by fermentation with E. coli NITE BP‐02351 in animal nutrition raises no safety concerns for consumers of animal products. The additive is not irritating to the skin or eyes and is not a skin sensitiser.
