    歐盟評估L-賴氨酸硫酸鹽作為所有動物飼料添加劑的安全性和有效性
    日期:2020-07-22  來源:食品伙伴網(wǎng)
       食品伙伴網(wǎng)訊  2020年7月21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)研究小組就L-賴氨酸硫酸鹽(l ‐lysine sulfate)作為所有動物飼料添加劑的安全性和有效性發(fā)表科學意見。
     
      據(jù)了解,L-賴氨酸硫酸鹽是由谷氨酸棒桿菌 KFCC 11043經(jīng)發(fā)酵制成的添加劑。經(jīng)過評估,專家小組認為該添加劑對目標物種、消費者和環(huán)境是安全的。L-賴氨酸硫酸鹽被認為是非反芻動物物種必需氨基酸L-賴氨酸的有效來源,為了使補充的L-賴氨酸對反芻動物和非反芻動物一樣有效,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 l ‐lysine sulfate produced by fermentation using Corynebacterium glutamicum KFCC 11043 when used as a nutritional additive in feed for all animal species. The active substance is l ‐lysine. The production strain qualifies for the qualified presumption of safety (QPS ) approach to safety assessment and was not detected in the final product. l ‐Lysine sulfate produced using C. glutamicum KFCC 11043 does not pose any safety concern associated with the production strain. l ‐Lysine sulfate produced by C. glutamicum KFCC 11043 is considered safe for the target species. When using l ‐lysine sulfate, the background sulfur/sulfate content in the compound feed should be taken into account. l ‐Lysine sulfate produced by C. glutamicum KFCC 11043 is safe for the consumer and for the environment. From the results of studies on the safety for the user of l ‐lysine sulfate produced by a different production strain, it was possible to conclude on the safety for the user of the product under assessment. l ‐Lysine sulfate produced by C. glutamicum KFCC 11043 is considered non‐toxic by inhalation, non‐irritant to skin or eyes and it is not a skin sensitiser. 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.
