據了解，這種6-植酸酶由Komagataella phaffii CGMCC 7.370產生。經過評估，專家小組認為在擬議的使用條件下，該添加劑對所有豬和所有禽類都是安全的。但不能就該添加劑對所有豬和所有禽類的功效做出結論。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 6-phytase (VTR-phytase) as zootechnical feed additive for all pigs and all avian species. The additive VTR-phytase consists of 6-phytase and it is available in solid and liquid forms. VTR phytase (liquid/solid) was produced by a genetically modified strain of Komagataella phaffii (CGMCC 7.370). The genetic modification of the production strain does not give rise to safety concerns. Viable cells of the production strain and its DNA were not detected in the final products. The additive does not pose any safety concern regarding the production strain. VTR phytase (liquid/solid) produced by Komagataella phaffii CGMCC 7.370 is safe for all Suidae and all avian species at the proposed conditions of use. The use of both forms of the additive under assessment in animal nutrition under the proposed conditions of use raises no safety concerns for consumers or for the environment. The liquid VTR phytase and powder VTR phytase are non-irritant to skin or eyes but should be considered skin and respiratory sensitisers. The additive has the potential to be efficacious in laying hens at 1,000 U phytase/kg complete feed. The conclusion can be extrapolated to other birds for egg production or breeding. The FEEDAP Panel cannot conclude on the efficacy of all pigs or growing poultry species.
