Bromelain is found in high levels in pineapples. As part of common commercial
kitchen, pineapple extracts are used as a meat tenderizer prior to cooking. Additionally,
eating too much very fresh pineapple can cause gum bleeding, swelling, and muscle
pains. Pineapple that has been cooked, heat-processed, or treated with common food
preservatives do not cause these same problems and cannot be used as a meat
tenderizer. Given what you know about bromelain and have learned throughout this
semester, explain why fresh pineapple is a better meat tenderizer than canned pineapple.
