賴氨酸硫酸鹽作為所有動物飼料添加劑的安全性

   食品伙伴網訊  2021年7月23日,據歐盟食品安全局(EFSA)消息,應歐盟委員會要求,歐盟動物飼料添加劑和產品(FEEDAP)研究小組就谷氨酸棒桿菌KCCM 80227生產的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表科學意見。

 

  經過評估,專家小組認為在建議的使用條件下該添加劑對目標物種、消費者和環境是安全的。評估中的添加劑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, EFSA was asked to deliver a scientific opinion on the safety and efficacy of l-lysine sulfate produced by Corynebacterium glutamicum KCCM 80227 as a nutritional feed additive for all animal species. The FEEDAP Panel concluded that the production strain C. glutamicum KCCM 80227 qualifies for the qualified presumption of safety (QPS) approach to safety assessment and is not detected in the final product. l-Lysine sulfate produced using C. glutamicum KCCM 80227 does not pose any safety concern associated with the production strain. The additive under assessment 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 KCCM 80227 is safe for the consumers, users and for the environment. The additive 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.
