    核心提示:2024年4月10日,據(jù)歐盟食品安全局(EFSA)消息,應(yīng)歐盟委員會(huì)要求,歐盟動(dòng)物飼料添加劑和產(chǎn)品(FEEDAP)研究小組就大腸桿菌CGMCC 7.460生產(chǎn)的L-色氨酸(l-tryptophan)作為所有動(dòng)物飼料添加劑的安全性和有效性發(fā)表科學(xué)意見。
       食品伙伴網(wǎng)訊  2024年4月10日,據(jù)歐盟食品安全局EFSA)消息,應(yīng)歐盟委員會(huì)要求,歐盟動(dòng)物飼料添加劑和產(chǎn)品(FEEDAP)研究小組就大腸桿菌CGMCC 7.460生產(chǎn)的L-色氨酸(l-tryptophan)作為所有動(dòng)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(fèi)者和環(huán)境是安全的。在缺乏數(shù)據(jù)的情況下,專家小組無法就該添加劑作為皮膚、眼睛刺激物或皮膚敏化劑的可能性得出結(jié)論。評估中的添加劑被認(rèn)為是非反芻動(dòng)物物種氨基酸L-色氨酸的有效來源。為了使補(bǔ)充的L-色氨酸對反芻動(dòng)物和非反芻動(dòng)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, EFSA was asked to deliver a scientific opinion on the safety and efficacy of the feed additive consisting of l-tryptophan produced by fermentation with Escherichia coli CGMCC 7.460 when used as a nutritional additive in feed and water for drinking for all animal species and categories. The production strain is not genetically modified. Viable cells of the production strain were not detected in the final additive. The additive does not give rise to any safety concern regarding the production strain. The use of l-tryptophan (≥ 98%) produced with E. coli CGMCC 7.460 to supplement feed is safe for non-ruminant species. There may be a risk for an increased production of toxic metabolites when unprotected tryptophan is used in ruminants. The EFSA Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) has concerns on the safety of the simultaneous oral administration of l-tryptophan via water for drinking and feed due to possible amino acid imbalances and hygienic reasons. The use of l-tryptophan produced with E. coli CGMCC 7.460 in animal nutrition raises no safety concerns to consumers of animal products and to the environment. In the absence of data, the FEEDAP Panel cannot conclude on the potential of the additive to be irritant to skin or eyes, or on its potential to be a dermal sensitiser. The endotoxin activity of the additive in combination with the high dusting potential may represent a risk of exposure by inhalation to endotoxins for users. The additive l-tryptophan is regarded as an effective source of the amino acid l-tryptophan for all non-ruminant species. To be as efficacious in ruminants as in non-ruminants, it should be protected from ruminal degradation.
