Product storage stability
Samples from three product batches were kept in plastic bags at room temperature or 40°C for 12 months. At room temperature, 7% of the xylanase and 9% of the galactosidase activity was lost. When stored at 40°C, the enzyme activity loss increased to 12% for the xylanase and 14% for the galactosidase.
Storage stability in premix and feed
The product was added to a vitamin/mineral premix and stored for six months at 25°C. After six months, 10% of the xylanase and 3% of the galactosidase were lost.
The stability of the product in chicken feed was observed for an unspecified duration. 3% less xylanase and 12% less galactosidase were observed in the mash feed. In pelleted feed, 12% less xylanase and 8% less galactosidase were seen.
Heat stability
Mash feed based on maize and soybean meals was pelleted at 70°C. Eight per cent of the xylanase activity was lost during pelleting. For the galactosidase, the activity was reduced by 11%.
Physical properties
The product contains 2% xylanase, 2% galactosidase, 95% kieselgur and 1% dextrin. The variation of enzyme activity was tested in samples from six batches. The average content of GALU was 45 GALU/gram, with a CV of 6%. The average content of galactosidase was 58 AXC/g, with a CV of 8%.
Laser diffraction was used to measure the particle size distribution. Forty-two per cent of the particles were <100 µm, 10 % < 10 µm.
The dusting potential was measured to <0.1 g/m3. The bulk density ranged from 575 to 600 kg/m3.
Homogeneity
The product was added to a pig diet to test the capacity to mix homogeneously. Ten subsamples of the feed were collected and analysed. The CV was 6% for the xylanase and 8% for the galactosidase.
Handling
The EU authorisation states: "For users of the additive and premixtures, feed business operators shall establish operational procedures and organisational measures to address potential risks resulting from their use. Where those risks cannot be eliminated or reduced to a minimum by such procedures and measures, the additive and premixtures shall be used with personal protective equipment, including skin, eyes and breathing protection."
