Papain is widely used in the food industry as a meat tenderizer due to its ability to break down tough protein fibers, making meat more palatable and easier to digest. It is also employed in the production of protein hydrolysates and in the brewing process to prevent chill haze by degrading proteins that cause cloudiness. In the medical field, papain is utilized in wound care and debridement products to remove dead tissue and promote healing. Additionally, it is found in some digestive supplements to aid in protein digestion and alleviate digestive discomfort. In cosmetics, papain is incorporated into exfoliating products to gently remove dead skin cells, improving skin texture and appearance.
