Can You Make Jello with Fresh Pineapple?

Can You Make Jello with Fresh Pineapple? | Science Fair Projects | STEM Projects
Ever wondered if you can make Jello with fresh pineapple instead of canned? In this project, you'll find out if it's possible by testing the effects of the protein-degrading enzyme bromelain on the gelatin protein in Jello.


The hypothesis is that the bromelain enzyme in fresh pineapple will degrade the gelatin protein in Jello, making it impossible to gel.

Method & Materials

You will make two batches of Jello, one with canned pineapple and one with fresh pineapple, and observe the results.
You will need fresh pineapple, canned pineapple, Jello, a bowl, boiling and cold water, a spoon, paper cups, and a knife.


The results of this experiment showed that the Jello made with canned pineapple gelled, while the Jello made with fresh pineapple did not. This is because the bromelain enzyme in the fresh pineapple degraded the gelatin protein, digesting it into a bowl of amino acids.

Why do this project?

This science project is interesting and unique because it shows how the enzyme bromelain can have a dramatic effect on the properties of Jello.

Also Consider

Experiment variations to consider include testing other fruits that contain protein-degrading enzymes, and determining the temperature at which the enzyme denatures.
