    歐盟評估一種L-賴氨酸堿和L-賴氨酸鹽酸鹽作為所有動物飼料添加劑的安全性和有效性
    日期:2021-04-30  來源:食品伙伴網(wǎng)
       食品伙伴網(wǎng)訊  2021年4月28日,據(jù)歐盟食品安全局EFSA)消息,應(yīng)歐盟委員會要求,歐盟動物飼料添加劑和產(chǎn)品(FEEDAP)研究小組就谷氨酸棒桿菌KCCM 80183生產(chǎn)的L-賴氨酸堿和L-賴氨酸鹽酸鹽( l‐lysine (base) and l‐lysine monohydrochloride)作為所有動物飼料添加劑的安全性和有效性發(fā)表科學(xué)意見。
     
      經(jīng)過評估,專家小組認(rèn)為該添加劑對消費者和環(huán)境是安全的。谷氨酸棒桿菌KCCM 80183生產(chǎn)的L-賴氨酸堿。被認(rèn)為吸入有害,對皮膚和眼睛無刺激性,也不是皮膚過敏物質(zhì)。評估中的添加劑被認(rèn)為是非反芻動物物種氨基酸L-賴氨酸的有效來源。為了使補(bǔ)充的L-賴氨酸對反芻動物和非反芻動物同樣有效,需要防止其在瘤胃中降解。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 concentrated liquid l‐lysine (base) and l‐lysine monohydrochloride (HCl) produced using Corynebacterium glutamicum KCCM 80183 when used as nutritional additives in feed and water for drinking for all animal species. The active substance is l‐lysine. Concentrated liquid l‐lysine (base) and l‐Lysine HCl produced by the strain C. glutamicum KCCM 80183 do not pose any safety concern as regards the genetic modification of the production strain. The use of the additives under assessment in supplementing feed to compensate for l‐lysine deficiency in feedingstuffs is safe for the target species. The FEEDAP Panel has concerns about 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 both forms of l‐lysine produced by fermentation using C. glutamicum KCCM 80183 in animal nutrition is considered safe for the consumers and for the environment. Concentrated liquid l‐lysine (base) produced by C. glutamicum KCCM 80183 is considered hazardous by inhalation, not irritant to skin and eyes and it is not a skin sensitiser. l‐Lysine HCl produced by C. glutamicum KCCM 80183 is considered hazardous by inhalation, it is not irritant to skin but mildly irritant to eyes and it is not a skin sensitiser. The additives under assessment are considered as efficacious sources 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.
