Can you put pineapple in jello

Fresh pineapple prevents gelatin from setting up because it contains a protease called bromelain that digests the links formed between collagen molecules that make the liquid turn into a gel. Other plants also produce proteases that prevent gelatin from setting. These include fresh papaya, mango, guava, and kiwi. Pineapple, kiwi and papaya all contain proteolytic enzymes, in other words enzymes capable of breaking down protein molecules.

And gelatin, the substance that makes Jell-O gel, is a protein. Pineapples are popular for fresh eating, smoothies, and for baking. In many cases, canned pineapple can be substituted for fresh pineapple and vice versa in equal measure, which is good to know when you only need a small amount of pineapple for a recipe. If you like making gelatin for dessert, the box often recommends not adding certain kinds of fruit, including pineapple, kiwi, mango, ginger root, papaya, figs or guava.

People have a hard time getting the gelatin to solidify when they add these fruits. Key Takeaways: Fruits That Ruin Gelatin Pineapple, kiwi, papaya, mango, and guava are examples of fruits that cause a problem. Heat inactivates proteases, so cooking fruit before adding it to gelatin prevents any issue. Canned fruit has been heated, so it is also acceptable for use in gelatin desserts. Jell-O never sold in the UK.

Canned pineapple doesn't have the same effect because heat from canning inactivates bromelain. Other plants also produce proteases that prevent gelatin from setting.
