Bromelain is an enzyme found in uncooked pineapple juice that breaks down proteins. When gelatin is mixed with pineapple juice, bromelain digests the proteins in the gelatin, preventing it from forming the gel structure necessary for solidification. This interference with the protein bonding process is why gelatin fails to set when combined with fresh pineapple juice. Cooking the pineapple destroys the bromelain, allowing gelatin to solidify properly.
Kiwi and Pineapple contain an acit that will not set in gelatin
To ensure gelatin sets properly when using fresh pineapple, you should either cook the pineapple briefly to deactivate the enzyme bromelain, which prevents gelatin from solidifying, or use canned pineapple instead, as the canning process destroys the enzyme. You can also use crushed pineapple, but make sure it's cooked to avoid the same issue. After preparing the pineapple, mix it with the gelatin and allow it to cool to set.
pineapple, kiwi, mango, gingerroot, figs and gauva are the fruits which will prevent gelatin from hardening.
It may have to do with the acidity of the fruit. I know that pineapple, kiwi, gingerroot, papaya, figs or guava will not work.

Pineapple contains an enzyme which prevents gelatin from setting. Heat destroys (denatures) enzymes.
Fresh pineapple juice contains the enzyme bromelain, which breaks down proteins. When added to gelatin, bromelain prevents the protein strands in the gelatin from forming a stable network, which is essential for the jello to set. In contrast, canned pineapple juice is safe to use because the canning process destroys the bromelain enzyme.
Jello does not solidify properly when mixed with fresh pineapple juice because it contains bromelain, an enzyme that breaks down the proteins in gelatin, preventing it from setting. However, canned pineapple juice is safe to use because the canning process deactivates the enzyme. Additionally, the acidity of pineapple juice does not interfere with gelatin setting, but it's the bromelain that is the primary concern. If you want to use fresh pineapple, you can heat it to deactivate the enzyme before mixing it with Jello.
Pineapples contain an enzyme called bromelain. THis enzyme stops the Jello from jelling because it breaks dowm the strands of protein that form Jello. Cooking the pineapple denatures this enzyme therefore preventing it from stopping the Jello.
you could make it into juice and then add it to the jello.
Yes, as long as you do not use pineapple juice. this prevents the gelatin from setting.
