The increase in tuna production in Indonesia has introduced waste-management challenges. Utilizing pepsin from tuna stomachs for beef tenderization is a potential solution for the food industry. This study aimed to assess the effects of different pepsin concentrations on beef characteristics. This study used a completely randomized factorial design with one factor: beef was treated with 0, 14,000, and 28,000 U/mg pepsin and stored at 4 °C for four days. The results showed that 28,000 U/mg pepsin significantly lowered pH, decreased weight percentage change, increased water-holding capacity, and reduced texture compared to other treatments. Histological examination revealed gradual degradation of meat structure, especially in collagen-deficient areas. Tuna stomach pepsin plays a crucial role in altering the physical and histological characteristics of the beef.
