Pineapple contains an enzyme which prevents Gelatin from setting. Heat destroys (denatures) enzymes.
No, the enzymes in fresh pineapple prevent the jello from gelling.
That depends on the weight of the pineapple but there is no specific weight of pineapples
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.
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.
pineapples are fresh in spring.
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.
Pineapples should be added towards the end. Watch the ham cook. When there are about 15 minutes left, slice up your pineapple. Then add them to the ham. If you are using fresh pineapple, it is important not to add the slices to the ham too early. Fresh pineapple contains an enzyme that will cause the ham to turn mushy. Better yet, use canned pineapple, the canning process destroys the enzyme. Also, do not store the leftover ham with the pineapple slices.
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.
There are actully quite a lot of pineapple types, i can't name them all cause i don't know them all, but what i do know is that, there are 3 main types of pineapple. These ones are the most well known pineapple types. The Spanish type, Cayenne type, and last but not least the Queen. The Spanish one is called Red Spanish as the Cayenne's full name is the smooth cayenne, and the Queen i don't know its full name its known as the queen you don't have to say the full name. Hope you understand!
Pineapples like lots of sun and grow well in tropical regions around the world. In addition to Hawaii, pineapple for the fresh market is grown in Costa Rica, Honduras, Mexico, Dominican Republic, El Salvador, Ecuador and Nicaragua.
No. Metal in a microwave will spark and burn.
I really honestly do not think that you can can fresh pineapple because normally it is canned for you
