It was Christmas
• Grocery stores were closed.• I had hungry guests arriving. • I started cooking lots of food.• I started making my mandarin orange, walnut,
dried cranberry, raspberry jello mold.• I realized I forgot to buy the mandarin oranges.
• Oh No!
• I mixed up the mold, added chopped fresh pineapple and put my mix in the refrigerator to set.
• 2 hours later I checked on my mold……..
Well,
After looking at the expiration date on the box of jello I used (it was OK) and running to Google, I found:
Pineapple contains a protein degrading enzyme called bromelain.
Jello contains gelatine which is a protein.
BINGO!
I must have missed this lesson in Chemistry Lab.
Here is a video showing what happens:

• Now, Betty has found a way to remedy this!•http://www.youtube.com/watch?v=1nfes2DEl
68• No FRESH Pineapple
• YAY, Betty!
Why does canned pineapple work?
Because heat kills the bromelain enzyme, and canned pineapple is heated as part of the canning
process.You can read more about the chemistry here:

As for me, live and learn always. No jello mold this year for Christmas.
