6-phytase EC 3.1.3.26
Additive composition
Preparation of 6-phytase, produced by Trichoderma reesei (ATCC SD-6528), having a minimum activity of 20 000 FTU ( 1 ) /g.
Solid form
Characterisation of the active substance:
6-phytase (EC 3.1.3.26), produced by Trichoderma reesei (ATCC SD-6528)
Analytical method
( 2 )
For the quantification of 6-phytase activity in the feed additive and premixutes:
—
colorimetric method based on the enzymatic reaction of phytase on the phytate.
For the quantification of 6-phytase activity in feedingstuffs:
—
colorimetric method based on the enzymatic reaction of phytase on the phytate EN ISO 30024.

In the directions for use of the additive and premixtures, the storage conditions and stability to heat treatment shall be indicated.
2.
Maximum recommended dose: 2 000 FTU/kg complete feed.
3.
For users of the additive and premixtures in a feed business, operational procedures and appropriate organisational measures shall be established to address hazards by inhalation, dermal contact or eyes contact. Where the dermal, inhalator or eyes exposure cannot be reduced to an acceptable level by these procedures and measures, the additive and premixtures shall be used with appropriate personal protective equipment.
