2019年4月1日，欧盟食品安全局发布关于酶制剂Hemicell®‐L（β-甘露聚糖酶）作为产蛋鸡等小型家禽饲料添加剂的安全性和有效性。据了解，酶制剂Hemicell®‐L是一种内切1,4‐β‐甘露聚糖酶的液体制剂，作为目标物种的动物技术添。欧盟动物饲料添加剂和产品（FEEDAP）研究小组经过评估认为该添加剂加剂在79,200 U/kg的浓度下可能有效。部分原文报道如下：The additive Hemicell®‐L is a liquid preparation of endo‐1,4‐β‐mannanase that is authorised as a zootechnical feed additive for chickens for fattening. The applicant has requested the renewal of the authorisation, new uses and the modification of the manufacturing process including the change of the production strain. The new production strain is a genetically modified strain of Paenibacillus lentus obtained from a strain that has been evaluated previously by EFSA and considered to be safe. The EFSA Panel on Additives and Products or Substances used in Animal Feed （FEEDAP） evaluated the genetic modification and concluded that the sequences introduced to obtain the production strain did not raise safety concerns. The production strain and its DNA were not detected in the additive. The Panel concluded that the additive is safe for chickens for fattening and turkeys for fattening at the recommended level. These conclusions were extended or extrapolated to the other target species under application.
