This video demonstrates the setup, operation, and key moments during typical use of Acid Protease Enzyme. You will see how this enzyme, extracted from Aspergillus niger, functions optimally at pH 2.0-4.0 and temperatures of 50-55°C. We'll walk through its applications in brewing, food processing, feed additives, and leather processing, showcasing how it cleaves peptide bonds to produce small peptides and amino acids.
