    歐盟評(píng)估一種內(nèi)切-1,4-β-木聚糖酶作為家禽飼料添加劑的安全性和有效性
    日期:2022-07-22  來(lái)源:食品伙伴網(wǎng)
       食品伙伴網(wǎng)訊  2022年7月21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)研究小組就一種內(nèi)切-1,4-β-木聚糖酶(endo‐1,4‐β‐xylanase )作為家禽飼料添加劑的安全性和有效性發(fā)表科學(xué)意見。
     
      據(jù)了解,該添加劑是由Komagataella phaffii ATCC PTA-127053生產(chǎn)的。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 endo-1,4-β-xylanase produced by Komagataella phaffii ATCC PTA-127053 (Xygest HT) as a zootechnical feed additive for poultry. The production strain is genetically modified. No viable cells nor recombinant DNA of the production strain were detected in the final product. Therefore, the Panel concluded that the additive does not pose any safety concern regarding the production strain. The FEEDAP Panel concluded that Xygest HT is considered safe for chickens for fattening at 30,000 U/kg and in laying hens at 45,000 U/kg, with a wide margin of safety. These conclusions can be extended to chickens reared for laying/breeding and extrapolated to all poultry species for fattening and reared for laying/breeding and to ornamental birds. The conclusions on laying hens are extrapolated to all laying poultry species. The use of Xygest HT in animal nutrition is of no concern for consumer safety and this feed additive is considered safe for the environment. The Panel also concluded that Xygest HT is not irritant to the eyes and skin but should be considered a dermal and a respiratory sensitiser. The Panel concluded that the additive Xygest HT has a potential to be efficacious for laying hens under the proposed conditions of use and this conclusion can also be extrapolated to all laying poultry species. The Panel could not conclude on the efficacy of the product for chickens for fattening due to insufficient data.
