    歐盟評(píng)估谷氨酸棒桿菌CGMCC 23982生產(chǎn)的L-賴(lài)氨酸硫酸鹽作為所有動(dòng)物飼料添加劑的安全性和有效性
    日期:2025-04-27  來(lái)源:食品伙伴網(wǎng)
       食品伙伴網(wǎng)訊  2025年4月25日,據(jù)歐盟食品安全局EFSA)消息,應(yīng)歐盟委員會(huì)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CGMCC 23982發(fā)酵生產(chǎn)的L-賴(lài)氨酸硫酸鹽(L-lysine sulfate)作為所有動(dòng)物飼料添加劑的安全性和有效性發(fā)表科學(xué)意見(jiàn)。
     
      經(jīng)過(guò)評(píng)估,專(zhuān)家小組認(rèn)為該添加劑對(duì)目標(biāo)物種、消費(fèi)者和環(huán)境是安全的。評(píng)估中的添加劑被認(rèn)為是所有非反芻動(dòng)物物種氨基酸L-賴(lài)氨酸的有效來(lái)源。為了使補(bǔ)充的L-賴(lài)氨酸對(duì)反芻動(dòng)物和非反芻動(dòng)物同樣有效,需要防止其在瘤胃中降解。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-lysine sulfate produced by fermentation with a non-genetically modified strain of Corynebacterium glutamicum (CGMCC 23982) when used as a nutritional additive in feed for all animal species. The active substance is l-lysine. The FEEDAP Panel concluded that the production strain qualifies for the qualified presumption of safety (QPS) approach to safety assessment; therefore, l-lysine sulfate produced with C. glutamicum CGMCC 23982 does not pose any safety concern associated with the production strain. l-Lysine sulfate produced with C. glutamicum CGMCC 23982 is considered safe for the target species when administered via feed. When using l-lysine sulfate, the background sulfur/sulfate content in the compound feed should be taken into account when formulating diets. The FEEDAP Panel has concerns on the use of l-lysine sulfate in water for drinking. l-Lysine sulfate produced with C. glutamicum CGMCC 23982 is safe for the consumer and for the environment. With regard to user safety, the additive should be considered irritant to skin, eyes and the respiratory tract. Any exposure to the additive is a risk. l-lysine sulfate is considered as an efficacious source of the essential amino acid l-lysine for non-ruminant animal species. For the supplemental l-lysine to be as efficacious in ruminants as in non-ruminant species, it would require protection against degradation in the rumen.
