Pepsin is widely used in the food industry for the production of protein hydrolysates, which are essential in creating dietary supplements, infant formulas, and processed meat products to enhance tenderness and digestibility. It aids in breaking down complex proteins into simpler, more digestible peptides and amino acids, making it valuable for individuals with digestive disorders or those requiring easier protein absorption. While not primary, pepsin can support processes like cheese coagulation in combination with other enzymes.

In the pharmaceutical sector, pepsin is utilized in the preparation of certain medications, particularly those designed to treat digestive issues. It is a key component in digestive enzyme supplements, helping to improve protein digestion and alleviate symptoms of conditions like hypochlorhydria or indigestion.

Additionally, pepsin finds application in laboratory research, where it is used to study protein structure and function. It is employed in protein digestion experiments to analyze peptide fragments, aiding in the understanding of protein behavior and interactions.

In the leather industry, pepsin is used during the dehairing and bating processes of animal hides, where it helps to remove hair and other unwanted proteins, preparing the hides for tanning.

Overall, pepsin’s ability to efficiently break down proteins makes it a versatile enzyme across various industries, from food and pharmaceuticals to research and manufacturing.
