Lab report on gelatin and pineapple juice
Olivia eberli ap biology-5 october 11, 2011 lab report enzymes and substrates: a jell-o and pineapple lab introduction: the purpose of this experiment was to see how bromelain would affect the formation of the jell-o certain enzymes can only affect certain substrates which is a protein. I think the best way to have done this experiment would have been to use fresh pineapple juice which contains natural bromelain did you ever try making jello with fresh pineapple it won’t gel because the bromelain digests the gelatin. Background: bromelain is a natural enzyme that could be found in the juice, stem, and fruit of the pineapple the enzyme, bromelain has been used as a digestive enzyme to aid the internal organs in digestion. I'm trying to figure out a lab and someone hinted that i should use these three things and the problem is i don't know how to put it together i had one idea and itd be me having different temperatures of pineapple juice and pouring them into cups of gelatin and watching the reaction of it if you have any similar experiments or tips i'd appreciate it.

The enzyme in pineapple juice that is responsible for the breakdown of collagen is bromelin the process of canning pineapple denatures the bromelin, rendering it incapable of catalyzing the break down of gelatin.
In this lab, we tested the effects of ph on the enzyme bromelain by altering the ph of liquid jello samples and then added fresh pineapple juice for the bromelain. In this lab we will be investigating just how much bromelain (protease found in the pineapple juice) you will need to prevent 10 ml of gelatin from congealing in other worlds, how much pineapple juice will it take to make the gelatin still liquid after refrigeration. In the two beakers of gelatin above, fresh pineapple was added to the one on the left and canned pineapple to the one on the right the enzyme protease, present in the fresh pineapple on the left, broke down the structure of the gelatin liquefying it.
