Functional group: digestibility enhancers 4a1641(i) DSM Nutritional Products Ltd represented by DSM Nutritional products Sp. Z o.o 6-phytase (EC 3.1.3.26) Additive composition Preparation of 6-phytase produced by Aspergillus oryzae DSM 14223 having a minimum activity of: liquid form: 20 000 FYT ( 1 ) /g Characterisation of the active substance 6-phytase produced by Aspergillus oryzae DSM 14223 Analytical method ( 2 ) Colorimetric method based on reaction of vanadomolybdate on inorganic phosphate produced by action of 6-phytase produced by Aspergillus oryzae DSM 14223 on a phytate-containing substrate (sodium phytate) at pH 5,5 and 37 °C, quantified against a standard curve from inorganic phosphate. Salmonids — 750 FYT — 1. In the directions for use of the additive and premixture, indicate the storage temperature, storage life, and stability to pelleting. 2. For use in feed containing more than 0,23 % phytin-bound phosphorus. 3. For safety: breathing protection, glasses and gloves shall be used during handling. 25 March 2021 ( 1 ) One FYT is the amount of enzyme that releases 1 μmol of inorganic phosphate from sodium phytate per minute under reaction conditions with a phytate concentration of 5,0 mM at pH 5,5 and a temperature of 37 °C during 30 minutes incubation.
