In cooked pineapple, the enzymes decrease during the cooking process whereas in fresh pineapple, the maximum amounts of the enzyme Bromelain exists. Bromelin Lab Design Closure: The canned pineapple was heated before it was canned which deactivated the bromelain.

What did we learn? As students work, I circulate around to see what students might need and to pose different questions to be sure that everyone knows the lab plan, knows their job, and is doing their job.
