Papain is a natural proteolytic enzyme found mainly in the stems, leaves and fruits of papaya. It appears as a fine powder, usually off-white to pale yellow. It is a proteolytic enzyme that helps break down proteins into smaller peptides or amino acids.
Papaya extract has a wide range of specificity. The enzyme is often used in the food industry as a meat tenderizer, or in beer and other beverages. Or as an active ingredient in dietary supplements and personal care products.
