Fresh pineapple contains the enzyme bromelain that has protease activity. Fresh pineapple can be used as a marinade to tenderize tough meat. However, canned pineapple that has been heated cannot. Why? What would you predict would be the optimum temperature for a lactase, a digestive enzyme that functions inside the human intestine?

Step 1
When fresh pineapple is used as a marinade, the bromelain enzyme breaks down the collagen fibers in the meat, tenderizing it. ** Show more…

We used different types of pineapple as sources of the enzyme bromelain and looked at whether it can affect the setting of gelatin. Why is it possible to make Jell-O with canned pineapple chunks but not with fresh pineapple chunks? Select one: a. All the answers are correct. b. The fresh pineapple chunks still have live enzymes that will prevent the Jell-O from setting. c. Canned pineapple chunks are heated during the canning process; therefore, there are no active enzymes in the canned pineapple. d. None of the answers are correct.

74. Papaya and pineapple fruits contain proteolytic enzymes that can degrade collagen. a. Cooking meat with these fruits helps to tenderize the meat. How does this work? b. A cook decides to flavor a gelatin dessert with fresh papaya and pineapple. The fruits are added to a solution of gelatin in hot water, then the mixture is allowed to cool. What is the result and how could the cook have avoided this?
