Fresh pineapple contains an enzyme which prevents jelly, Jell-O, or gelatine, from setting. That enzyme is destroyed during the cooking or canning process, so pineapple can be used in jellies.
The same applies to fresh kiwi fruit. If you have fresh pineapple or kiwi fruit that you want to set in jelly you'll need to cook the fruit in some way first. The simplest way is to cut the fruit into cubes, the size you want for your jelly, and put it in a container with some water, cover, and microwave until the fruit is steaming.
Uncover and cool slightly; refrigerate until cold: now you're ready to make jelly.

How to make jello with canned pineapple?
you cant -_-
Does canned pineapple keep jello from setting up?
The acids which build up from canned fruit of all varieties may slow the set time of jello, but should not prevent it entirely.
How could you successfully make jello with pineapple in it?
You have to cook the pineapple first. Jello won't solidify if you add fresh pineapple.Because pineapples contain proteases, enzymes that break down proteins. Since jello mixes are mostly made of collagen from animal parts, or proteins, pineapples break them down to their simplest forms. When you boil pineapple, it denatures the protease and you should be able to make pineapple jello then.
Can you make jello using frozen pineapples?
No you cannot make jello with frozen pineapples because the pineapple, like kiwi fruit, contains an enzyme that will break down the proteins such as the collagen in gelatin, which will prevent the jello from setting.More information:You can use frozen pineapple to make jello provided it's been cooked before freezing.If it wasn't cooked, then you will have to cook it before making jello. Just cut it to the size you want for your dessert, cover it with pineapple juice, and microwave until hot and steaming. Refrigerate till it's cooled, then make your jello as usual.Frozen pineapply will be softer once cooked than if you started with fresh, unfrozen pineapple.
Can you make Jell-o using fresh pineapples instead of canned pineapples?
No, the enzymes in fresh pineapple prevent the jello from gelling.
Why does pineapple not work in gelatin?
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.
What happens when you add fresh pineapple juice to jello?
Due to the bromelain enzyme in fresh pineapple, the jello will not set. Jello has the protein gelatin in it, and the bromelain prevents the gelatin molecules to bond with other gelatin molecules. If you make two molds of jello, one with pineapple, one without, you will find that only the one without pineapple will set. If you use canned pineapple, the jello will set because canned products are heated to eliminate microbes, but it also destroys or greatly reduces the amount of enzymes present.
What fruit will make jello spoil the fastest?
Pineapple, mango and papaya contain proteases, enzymes that break down protein, which will digest the gelatin and prevent it from setting. If you use canned fruit which has been partially cooked then the fruit will no longer have active enzymes in them though.
Why cant you make jello with fresh fruit in it?
You can just not with these fruits: Pineapple (fresh, canned is fine) Kiwi, Figs and Papaya. these fruits just wont set with it. I'm pretty sure you put fruit in before it sets.
What flavors of jello have NO red food coloring?
Pineapple, Lemon, Lime
Why can't you put pineapples in jello?
Pineapple, mango, guava, and kiwi all do not solidify in jell-o. They do this because all of them contain a protein in a class called protease. Protease is a protein that can break up most other proteins. I this case, they break up the gelatin in jell-o, which stops it from solidifying. (A tip for making jell-o: If you would like to use a fruit that you know has protease in it, then just cook it. Cooking the fruit inactivates the protease, allowing the jell-o to set).
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.
