Overview:Acid proteasederived from strains of Aspergillus Niger, under the condition of low pH,hydrolyze protein effectively, used in animal feed, feed-additives and feedcompositions as exogenous enzymes in the feed industry, or treat vegetableproteins.Action Mechanism:Acid protease contains aspartate inits active center, which can widely cut the peptide bond in amino acid, preferto cut the peptide bond between aromatic or hydrophobic amino acid residues atboth ends, especially the peptide bond between aromatic amino acid and otheramino acid, producing small peptides and amino acids.Product Characteristics1. Product specifications: 10,000 u/g~50,000u/g. powdered solid, enzyme fineness (0.4 mm standard screen) ≥80%2. Appearance characteristics: Brown powder3. Carrier: sweet potato flour4. Product standards: execute the People'sRepublic of China national standard GB/T23527-2009.Enzyme activity definition:One acidprotease activity unit is defined as the amount of enzyme which liberates 1μgtyrosine per minute from casein at 40℃ and pH 3.0.Optimum pHAcid protease’s optimum reaction pH is low, and basically coherent with thedigestive system of livestock and poultry. Make up for a lack of livestock andpoultry intestinal secretion of endogenous protease, improve proteindigestibility, reduce metabolic diarrhea when used in feed additive. Theeffective pH range is 2.0 to 6.0, the optimum pH is 4.0Temperature curveWhen temperature is lower than 30 ℃ or higher than 45 ℃, the relative enzy...
