*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 40℃, 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 enzyme is achieved through continuous technical research and bioengineering refinements.

  1. 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.
  2. 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 is200-250U/gat 35-42℃PH7.1-7.5 fordepilation and 10-20U/gat 35-42℃PH7.1-7.5 for softening.
  3. Neutral protease helps recovery of silver from waste film. Recommended dosage is20-23U/gat 45℃PH7.0-7.5.


Feed additives: Recommended dosage is 60-200g of neutral protease(50000U/g) per ton of complete feed. The product should be well mixed with feedstuff.


Solid: sealed in plastic inner bag, with a fabric outer bag, net weight 20kg/bag


Transport and store in cool dry place and avoid direct exposure to sunlight or moisture. Stored below 15℃in original sealed package, the activity of solid enzyme remains stable for a period of up to 6 months.
