    歐盟評(píng)估一種L-纈氨酸作為所有動(dòng)物飼料添加劑的安全性和有效性
    日期:2021-04-21  來(lái)源:食品伙伴網(wǎng)
       食品伙伴網(wǎng)訊  2021年4月19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 7.366發(fā)酵生產(chǎn)的L-纈氨酸(L‐valine)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,專家小組認(rèn)為該添加劑對(duì)消費(fèi)者和環(huán)境是安全的。由于缺乏數(shù)據(jù),研究小組就該添加劑通過(guò)吸入產(chǎn)生毒性、對(duì)皮膚或眼睛產(chǎn)生刺激或作為皮膚致敏物質(zhì)的可能性無(wú)法得出結(jié)論。評(píng)估中的添加劑被認(rèn)為是非反芻動(dòng)物物種氨基酸L-纈氨酸的有效來(lái)源。為了使補(bǔ)充的L-纈氨酸對(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 the safety and efficacy of the feed additive consisting of l‐valine produced by fermentation using a non‐genetically modified strain of Corynebacterium glutamicum (CGMCC 7.366). The additive is intended to be used in feed and water for drinking for all animal species and categories. The production strain is considered suitable for the qualified presumption of safety (QPS) approach to safety assessment. The FEEDAP Panel concludes that l‐valine produced using C. glutamicum CGMCC 7.366 is safe for the target species when supplemented in appropriate amounts to the diet according to the nutritional needs of the target species. The FEEDAP Panel has concerns on the use of amino acids in water for drinking for hygienic reasons, and due to the risk of imbalances when administered simultaneously via feed. The use of l‐valine produced using C. glutamicum CGMCC 7.366 in animal nutrition is considered safe for the consumer and for the environment. No conclusion could be drawn on the potential of l‐valine produced using C. glutamicum CGMCC 7.366 to be toxic by inhalation, irritant to the skin or eyes, or a dermal sensitiser due to the lack of data. The additive l‐valine produced by fermentation using C. glutamicum CGMCC 7.366 is regarded as an efficacious source of the essential amino acid l‐valine for non‐ruminant nutrition. For the supplemental l‐valine to be as efficacious in ruminants as in non‐ruminant species, it requires protection against degradation in the rumen.
