食品伙伴網(wǎng)訊  2019年2月28日，據(jù)歐盟食品安全局（EFSA）消息，應歐盟委員會要求，歐盟動物飼料添加劑和產(chǎn)品（FEEDAP）研究小組被要求就谷氨酸棒桿菌（Corynebacterium glutamicum）發(fā)酵產(chǎn)生的L-蘇氨酸（L‐threonine）作為飼料和水中營養(yǎng)添加劑用于所有動物物種的安全性和有效性發(fā)布科學意見。

 

　　經(jīng)過評估，F(xiàn)EEDAP研究小組認為，當添加適量時，谷氨酸棒狀桿菌產(chǎn)生的L -蘇氨酸作為添加劑對目標物種是安全的。

 

　　部分原文報道如下：

 

　　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‐threonine produced by fermentation with Corynebacterium glutamicum ■■■■■ when used as a nutritional additive in feed and water for drinking for all animal species and categories. The product under assessment is l‐threonine produced by fermentation with a ■■■■■ strain of C. glutamicum （■■■■■）。 l‐Threonine produced by C. glutamicum ■■■■■ is considered safe for the target species when supplemented in appropriate amounts to the diet. The FEEDAP Panel has concerns on the safety of the simultaneous oral administration of l‐threonine via water for drinking and feed. l‐Threonine produced using C. glutamicum ■■■■■ is safe for the consumer. The additive is not a skin or eye irritant and is not a skin sensitiser. Although the workers can be exposed by inhalation, the results of an acute inhalation study showed that risk of adverse effects by inhalation is low. l‐Threonine produced using C. glutamicum ■■■■■ is safe for the environment. The product under assessment is considered an efficacious source of the amino acid l‐threonine for all animal species. For l‐threonine to be as efficacious in ruminants as in non‐ruminant species, it requires protection against degradation in the rumen.
