Bromelain is a name for a group of protein-degrading enzymes from plants of the genus Bromeliaceae. It is found in particularly high concentrations in the stem and fruit of the pineapple plant (Ananas comosus). As proteases, they help to break down proteins and support the plant in its defence against microorganisms, insects and other pests.
Papain is an enzyme that is extracted from the papaya fruit. It is present in particularly high concentrations in the milky juice of unripe papaya fruits. As a protease, papain helps to break down proteins and supports the plant in its defence against diseases, insects and other pests.
