    歐盟評(píng)估一種β-甘露聚糖酶作為所有育肥家禽飼料添加劑的安全性和有效性
    日期:2023-06-14  來(lái)源:食品伙伴網(wǎng)
       食品伙伴網(wǎng)訊  2023年6月9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)研究小組就一種β-甘露聚糖酶(β-mannanase)作為所有育肥家禽飼料添加劑的安全性和有效性發(fā)表科學(xué)意見(jiàn)。
     
      據(jù)了解,這種β-甘露聚糖酶由黑曲霉 CBS 120604產(chǎn)生。經(jīng)過(guò)評(píng)估,專(zhuān)家小組認(rèn)為在建議的使用條件下該添加劑對(duì)目標(biāo)物種、消費(fèi)者和環(huán)境是安全的。該添加劑在30 U/kg飼料水平下對(duì)育肥家禽是有效的。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 a product containing β-mannanase produced by a non-genetically modified strain of Aspergillus niger (CBS 120604). The commercial name is Nutrixtend Optim and it is intended to be used as a zootechnical feed additive for all poultry for fattening. based on a tolerance trial in chickens for fattening and the no observed adverse effect level identified in a subchronic oral toxicity study in rats, the additive was considered safe for all poultry for fattening. The Panel concluded that the use of the product as a feed additive does not give rise to concerns for consumers and the environment. The additive is considered an irritant to skin and eyes and a dermal sensitiser. Due to the proteinaceous nature of the active substance, it is also considered a respiratory sensitiser. The Panel concludes that the additive has the potential to be efficacious as a zootechnical additive at the level of inclusion in feed of chickens for fattening of 30 U β-mannanase/kg complete feed. This conclusion was extrapolated to all poultry for fattening.
