Protease is widely used in various industries due to its ability to break down proteins into smaller peptides or amino acids. In the detergent industry, proteases are key components in laundry and dishwashing products, helping to remove protein-based stains like blood, egg, and sweat by breaking them into soluble fragments that can be easily washed away.

In food processing, proteases are used to modify proteins for improved texture, solubility, or nutritional value. For example, they are used in cheese production to help coagulate milk and develop flavor during aging. They also play a role in meat tenderization and in the brewing industry to prevent haze formation caused by protein-polyphenol complexes.

In the pharmaceutical and medical fields, proteases are used in wound debridement to remove dead tissue, promoting healing. They are also included in digestive enzyme supplements to aid patients with enzyme deficiencies. Additionally, certain proteases are used in research and biotechnology for protein analysis, such as in sample preparation for mass spectrometry or in recombinant DNA technology to cleave fusion proteins.

In leather processing, proteases help in dehairing and softening hides by breaking down non-collagen proteins, offering a more environmentally friendly alternative to harsh chemicals. Their specificity and efficiency under mild conditions make proteases valuable in sustainable industrial processes.
