*Activity: One Activity Unit is the amount of Neutral protease required to liberate the equivalent of 1 μg of Tyrosine per minute under the specified conditions and at 30°C, pH 7.5
Neutral protease is a water soluble enzyme that is capable of breaking down peptide bonds in proteins. It breaks down and increases protein dispersibility, solubility, palatability and digestibility. The effectiveness of this Neutral protease is achieved through continuous technical research and bioengineering refinements.
-
Neutral protease consumed by the animal along with the feed, will work under the harsh condition of the stomach to hydrolyze protein into peptides and amino acids, promote digestion and absorption, and yield greater return of profit from feed.
-
Neutral protease is also a very useful tool in the leather and fur industry, as it softens and adds suppleness to lower grade materials, yet at the same time strengthens the root of the fur. Fur treated with Neutral protease will show a noticeable sheen, and further processing such as dye will more easily bind. Overall, treated leather and fur result in higher quality and provide greater return to its user. Recommended dosage is 200-250U/g at 35-42°C PH7.1-7.5 for depilation and 10-20U/g at 35-42°C PH7.1-7.5 for softening.

Neutral protease helps recovery of silver from waste film. Recommended dosage is 20-23U/g at 45°C PH7.0-7.5.
