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.

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.
How long for jello to set with pineapple and cranberries?
Jello typically takes about 4 to 6 hours to set in the refrigerator. However, when using fresh pineapple, it's important to note that the enzymes in the fruit can prevent the jello from setting properly. To avoid this, you can either use canned pineapple or cook the fresh pineapple briefly to deactivate the enzymes. Cranberries, on the other hand, do not affect the setting process.
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.
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.
Does jello solidify with pineapple juice and acid?
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.
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.
Why does jello not become jello when a hot pureed fruit is added to it?
When hot pureed fruit is added to jello, the heat can break down the gelatin proteins, preventing them from forming a stable gel structure. Additionally, certain enzymes in fresh fruits, like pineapple and kiwi, can further interfere with gelatin's ability to set. This is why it's important to use cooked or canned fruit when making jello, as the cooking process deactivates these enzymes.
Why does fresh pineapple juice stop jello from setting?
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.
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.
