    歐盟評估一種L-組氨酸鹽酸鹽-水合物作為所有動物飼料添加劑的安全性和有效性
    日期:2021-06-01  來源:食品伙伴網(wǎng)
       食品伙伴網(wǎng)訊  2021年5月31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)研究小組就大腸桿菌 NITE SD 00268生產(chǎn)的L-組氨酸鹽酸鹽-水合物(l-histidine monohydrochloride monohydrate)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)為在建議的使用條件下該添加劑對消費者和環(huán)境是安全的。在缺乏數(shù)據(jù)的情況下,無法得出添加劑吸入后可能有毒、對眼睛有刺激性或?qū)ζつw過敏的結(jié)論。評估中的添加劑被認(rèn)為是氨基酸L-組氨酸的有效來源。為了使補充的L-組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 l-histidine monohydrochloride (HCl) monohydrate produced by fermentation with Escherichia coli  (NITE SD 00268) when used as a nutritional additive or as a feed flavouring compound in feed for all animal species. The active substance of the additive is l-histidine. The production strain has been modified by conventional mutagenesis and it does not raise safety concerns. The additive under assessment is safe for the target species when used as a nutritional additive to supplement the diet in appropriate amounts to cover the requirements, depending on the species, the physiological state of the animal, the performance level, the environmental conditions, the background amino acid composition of the unsupplemented diet and the status of some essential trace elements. This conclusion would cover its use as flavouring compound. l-Histidine HCl monohydrate produced by E. coli NITE SD 00268, when used at the proposed conditions of use, is safe for the consumer and for the environment. l-Histidine HCl monohydrate produced using E. coli NITE SD 00268 is not a skin irritant. In the absence of data, it is not possible to conclude on the potential of the additive to be toxic by inhalation, irritant to eyes or a skin sensitiser. The additive l-histidine HCl monohydrate is regarded as an effective source of the amino acid l-histidine when used as a nutritional additive. For the supplemental l-histidine to be as efficacious in ruminants as in non-ruminant species, it would require protection against degradation in the rumen. l-Histidine is efficacious as a flavouring compound.
