For the quantification of 6-phytase activity in the feed additive:
colorimetric method based on the enzymatic reaction of phytase on the phytate — VDLUFA Method Book, Vol. III, 27.1.1
For the quantification of 6-phytase activity in premixtures and mineral feeds:
colorimetric method based on the enzymatic reaction of phytase on the phytate — VDLUFA Method Book, Vol. III, 27.1.3
For the quantification of 6-phytase activity in feedingstuffs:
colorimetric method based on the enzymatic reaction of phytase on the phytate — EN ISO 30024.
