    歐盟評估一種L-精氨酸作為所有動物飼料添加劑的安全性和有效性
    日期:2022-08-01  來源:食品伙伴網(wǎng)
       食品伙伴網(wǎng)訊  2022年7月29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CGMCC 20516生產(chǎn)的L-精氨酸(l-arginine)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)為在擬議的使用條件下,該添加劑對目標(biāo)物種是安全的,但無法對使用者的安全性做出結(jié)論。評估中的添加劑被認(rèn)為是非反芻動物物種必需氨基酸L-精氨酸的有效來源。為了使補(bǔ)充的L-精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(bào)道如下:
     
      Following a request from the European Commission, the EFSA 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-arginine produced by fermentation using a non-genetically modified strain of Corynebacterium glutamicum (CGMCC 20516). The additive is intended to be used in feed and water for drinking for all animal species and categories. The production strain was considered suitable for the qualified presumption of safety (QPS) approach to safety assessment. No viable cells of C. glutamicum CGMCC 20516 were detected in the final product. l-Arginine produced using C. glutamicum CGMCC 20516 is safe for the target species when supplemented in appropriate amounts to the diet according to the nutritional needs of the target species, for the consumer and for the environment. In the absence of data, the FEEDAP Panel could not conclude on the safety of l-arginine produced by C. glutamicum CGMCC 20516 for the users. The additive l-arginine produced by fermentation using C. glutamicum CGMCC 20516 is regarded as an efficacious source of the essential amino acid l-arginine for non-ruminant species. For the supplemental l-arginine to be as efficacious in ruminants as in non-ruminant species, it requires protection against degradation in the rumen.
