Sources and Functions
Bromelains are enzymes found in the pineapple plant and fruit. Together with papain from papayas, and some others they are called "proteolytic enzymes" for their abilities to break down proteins. Bromelains are commercially used for tenderizing meat and treating sausage casings under the trade name of Ananase. They are also used for chillproofing beer, that is, preventing the development of cloudiness due to precipitation of proteins when beer is chilled, by having the enzymes break down these proteins.

Bromelain enzymes are commercially used to break down proteins, as anti-inflammatory agents for persons who have difficulties with the digestion of proteins, or suffering from athletic injuries.
