*Not recognized as an essential nutrient by the AAFCO Dog Food Nutrient Profiles
Enzyme Functionality Statement: Product contains enzymes. Protease for protein hydrolysis; Cellulase for cellulose hydrolysis; Amylase for starch hydrolysis.
1 One Hemoglobin Unit (HUT) of proteolytic (protease) activity is defined as the amount of enzyme that produces, in one minute under specified conditions (40°C, pH 4.7), a hydrolysate whose absorbance at 275 nm is the same as a solution containing 1.10 µg per ml of tyrosine in 0.006N hydrochloric acid.
2 One Cellulase Unit (CU) is that activity that will produce a relative fluidity change of one in five minutes in a defined carboxymethylcellulose substrate under the conditions of an assay (40°C, pH 4.5).
3 One Dextrin Unit (DU) of alpha-amylase activity as defined as that amount of enzyme that will dextrinize soluble starch at the rate of 1g per hour at 30°C.
