Regulation 3
The preparation of 6-phytase (EC 3.1.3.26), belonging to the additive category ‘zootechnical additives’ and to the functional group ‘digestibility enhancers’, is authorised as an additive in animal nutrition in accordance with the specifications in the following table(1).
(1) Enzyme activity expressed in PPU units, where one PPU is the amount of enzyme which liberates 1 micromole (μmol) of inorganic phosphate from sodium phytate per minute at pH 5.0 and 37°C. | ||
(2) This is a reference to the CAS Registry Number® assigned to this preparation by the Chemical Abstracts Service https://cas.org/cas-data/cas-registry. | ||
(3) This is the identification number allocated by the International Union of Biochemistry and Molecular Biology (IUBMB) https://iubmb.org. | ||
(4) The EINECS number is given in the European Inventory of Existing Commercial Substances, as published in O.J. No. C146A, 15.6.90, p.1. | ||
(5) Details of the analytical method is set out in the document referenced “D08/FSQ/CVH/SY/D/Ares(2009)173372” and last updated on 6th June 2016, available at: https://joint-research-centre.ec.europa.eu/publications/fad-2008-0040_en. | ||

Analytical method(5) | For the quantification of phytase activity in the feed additive, premixtures, feed materials and compound feed:
| |
Species or category of animal |
| |
Maximum age | Not applicable | |
Content of 6-phytase (units of activity (PPU)/kg of complete feed with a moisture content of 12%) | Minimum content |

This authorisation is a renewal of the authorisation granted under Commission Regulation (EU) No 277/2010, Commission Regulation (EU) No 891/2010 and Commission Implementing Regulation (EU) No886/2011. Those Regulations are revoked by regulation 7(1) of, and Schedule 14 these Regulations. This renewal differs from the previous authorisation as the minimum level of stock enzyme activity is reduced from 10,000 PPU/g to 5,000 PPU/g in the liquid forms.
