    2023年8月14日，欧盟食品安全局（EFSA）发布消息，欧盟食品安全局（EFSA）发布关于α-半乳糖苷酶和内切-1,4-β-葡聚糖酶作为育肥鸡、育肥小型家禽品种和产蛋鸡饲料添加剂的授权更新申请的评估。

据了解，α-半乳糖苷酶是由酿酒酵母CBS 615.94生产的，内切-1,4-β-葡聚糖酶是由黑曲霉CBS 120604生产的。经过评估，专家小组得出结论，该添加剂在授权使用条件下对所有动物物种、消费者和环境都是安全的。在授权更新的情况下，无需评估添加剂的功效。部分原文报道如下：部分原文报道如下：

Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the assessment of the application for renewal of Agal-Pro BL/BL-L®. The additive is a preparation of alpha-galactosidase produced by a genetically modified strain of Saccharomyces cerevisiae (CBS 615.94) and endo-1,4-beta-glucanase produced by a non-genetically modified strain of Aspergillus niger (CBS 120604). It is intended to be used as a zootechnical additive (functional group: digestibility enhancers) in chickens for fattening in its solid and liquid forms (Agal-Pro BL®and Agal-Pro BL-L®), and in minor poultry species for fattening and chickens reared for laying only in its solid form (Agal-Pro BL®). The applicant has provided evidence that the additive currently on the market complies with the existing conditions of authorisation. There is no new evidence that would lead the FEEDAP Panel to reconsider its previous conclusions. Thus, the Panel concludes that the additive remains safe for the target animals, consumers and the environment under the authorised conditions of use. Regarding user safety, the additive is considered an irritant to the skin and eyes and a dermal sensitiser. Due to the proteinaceous nature of the active substances, it should be considered a respiratory sensitiser. There is no need for assessing the efficacy of the additive in the context of the renewal of the authorisation.
