Let your kids hypothesize. Results - The water made no impression, and the pineapple juice did. As you start to boil the water label the bowls room temperature pineapple juice and hot pineapple juice. If instead of fresh pineapple, canned is used (cooked as part of the canning process), the bromelain is denatured by the heat and cannot facilitate the breakdown of collagen. Record observations on a data table. • … 8.With the spoon labeled (CP), add canned pineapple to the labeled container.

Adding fresh pineapple to Jell-O™ allows the bromelain to break down the gelatin's collagen, and the Jell-O™ will not set upon cooling. In this lab, we incubate fresh pineapple juice which contains bromelain (an enzyme mix), canned pineapple juice, and water with a gelatin preparation. This is because fresh pineapple has bromelain, a proteolytic enzyme that breaks down proteins. Pineapple contains a chemical called bromelain, which contains two enzymes capable of digesting proteins, called proteases. Add the fruit into the different bowls. The reason pineapple prevents Jell-O from setting is due to its chemistry. Container 2 has the fresh pineapple floating on top and still able to flow around in the gelatin liquid.
