據了解，α-半乳糖苷酶是由塔賓麴黴ATCC SD6740生產的，內切-1,4-β-木聚糖酶是由長枝木霉CBS 139997生產的。部分原文報道如下：

 

　　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 Capsozyme SB Plus as a zootechnical feed additive (digestibility enhancers) for chickens for fattening, chickens reared for laying and minor poultry species (for fattening and reared for laying). The additive co ntains two enzyme ingredients (α-galactosidase, produced by a non-genetically modified strain of?Aspergillus tubingensis; and endo-1,4-β-xylanase, produced by a non-genetically modified strain of?Trichoderma longibrachiatum) and is presented in solid form. In 2020, the FEEDAP Panel issued an opinion on this product. In that assessment, the Panel co nsidered the additive safe for the target species and the environment. The Panel co ncluded that the additive does not raise co ncern for genotoxicity but could not co nclude on co nsumer safety due to the limitations identified in the 90-day toxicity study. Owing to the lack of data, the Panel could not co nclude on the potential of the additive as a skin or eye irritant nor as a skin sensitiser. Moreover, the Panel could not co nclude on the efficacy of the additive for chickens for fattening due to the limited evidence provided. The applicant provided supplementary data to support the safety for co nsumers and the efficacy of the product in chickens for fattening. The FEEDAP Panel co ncluded that the data provided support the absence of toxicological risk for the consumer. Likewise, according to the new data submitted, the FEEDAP Panel co ncluded that the additive has the potential to be efficacious in chickens for fattening at the level of 14 GALU (α-galactosidase)/18 AXC (endo-1,4-β-xylanase) per kg feed, and this co nclusion was extended to chickens reared for laying and extrapolated to minor poultry species for fattening/reared for laying.
