The proteins in the pineapple called bromelain will break down the strands of protein in Gelatin that forms jello. Hence, the effect of a fresh piece of pineapple on gelatin is able to keep the gelatin liquidfied.

it is best for the pineapple to be frozen. If the pineapple is not frozen, the jello will not solidify. There is proteolytic enzyme in citrus fruits, which causes the jello to not solidify. It is best to boil the fruit or have it frozen.

Raw pineapple contains a protease enzyme that chops up the long protein molecules of the gelatin into short ones, this prevents setting.

Cooking of pineapple before adding it to gelatine destroys these protease enzymes, allowing the gelatin to properly set. Canned pineapple was cooked in the canning process.

Why does fresh pineapple keep gelatin from gelling?

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.

Why won't fresh pineapples solidify?

Pineapples are actually reasonably solid. The question may mean, "Why can't you make fresh pineapple jello?" Enzymes in the pineapple prevent protein molecules from "setting up" into the (semi)solid gelatin.


Will reheating your set jello still solidify?

Gelatin is a reversible colloid, so yes, if you melt a set jello, it should set again when chilled. However, other ingredients, such as pineapple, may alter the gelatin so that it does not set.
