Pepsin is widely used in the food industry for the production of protein hydrolysates, which are essential in creating dietary supplements, infant formulas, and sports nutrition products. It aids in breaking down proteins into smaller peptides, enhancing digestibility and nutritional value. In the pharmaceutical sector, pepsin is utilized in the preparation of digestive enzyme supplements to treat conditions like indigestion and low stomach acid. Additionally, it plays a role in laboratory research for protein digestion in biochemical studies and protein analysis. Its ability to cleave proteins at specific sites makes it valuable in various biotechnological applications, including the production of bioactive peptides.
