Which type of meat will tenderize most using cola drinks?
-To help Namibians use a cheaper, easier and always available type of meat tenderizer. Hypothesis:
Beef will tenderize most.
In my research,”Phosphoric Acid”, the main ingredient of cola drinks, is assumed to be of high enough concentration to deteriorate a piece of meat. So in this experiment, I want to prove if cola drinks can tenderize meat and what type of meat can it tenderize most. Plan:
The plan is to come up with my researches and seek help from others. Then, I have to understand every single step from the start until the end, to reach to my conclusions. -Variables
* The independent variable in this experiment is the kind of meat using: * BEEF
* The controlled variables are the following:
* Cola drink’s quantity
* Meat’s weight
* Bowl’s size
Meetings & Discussions:
At first, I researched for experiments that can be done and I ask myself how cola drinks can clean rust and by that I found out that it was because of phosphoric acid. So, that brought me up to the idea of this experiment.

10AM- NEXT DAY| Observance| Research and recorded|
5PM-NEXT DAY| Results| Recorded |
*The experiment was 24hrs.
-The meat has the same grams.
-The same number of hours on the meat used.
-The same amount of Coke poured on the meat.
Material & Apparatus used:
1. Meat: 60grams of Pork, beef and chicken
2. 330 ml can of cola (3cans).
3. Bowls of the same kind and size.
4. Weighing scale
5. Chopping board and knife
-Weigh the meat separately. The scale of the meat should be 60 grams. -Place the meat in bowls. Observe the colour, smell and texture. -With a help, add the 330 ml coke in each meat at the same time. -Observe what happens every time you see it.
-Final observance is after 24 hours.
-After 24 hours, observe the colour, smell, scale and texture. -Take out all the meat from the bowl and use a chopstick to feel, what meat is the softens (tenderize). Further Investigations:
-At first I had salmon.
: I changed it to chicken.
-The weighing scale was not working properly.
: We bought a new one.
-We added 2 cups of coke only, which was really little
: We used 330 ml can of cola.
-I should have compared 4-5 meats, instead of 3 only.
-I should have made the correct amount of cola(Exact amount). -I should have made the right scale.
5PM: (START OF EXPERIMENT)
1-Most 2-More/Medium 3-Least
MEAT| APPEANCE OF BUBBLES AFTER PORING| FLOAT| SMELLS LIKE -| COLOUR| Pork| 1| 3| Cola| Light Red/Pink|
Beef| 3| 2| Cola| Red|
Chicken| 2| 1| Cola| Light Pink|
MEAT| APPEARANCE OF BUBBLES|
AROUND 8AM (THE NEXT DAY):
N.B. Sedimentation is the process by which particles in suspension in liquid form sediment. Sediment is a material, originally suspended in a liquid, that settles at the bottom of the liquid when it is left standing for a long time. MEAT| SEDIMENTATION|
RESULTS AT 5PM:
N.B. Supernatant is usually a clear liquid above material deposited by sedimentation, precipitation, or centrifugation. MEAT| SUPERNATANT(CLEAR)| SEDIMENTS| TOP BUBBLES|
Pork| 1| 1| 1|
Beef| 2| 2| 2|
Chicken| 3| 3| 3|
MEAT| SCALE AFTER EXPERIMENT| SMELL| COLOUR|
Pork| 60grams| None| Lighter than before/Light brown or pink| Beef| 60grams| A little bit of cola| Pale|
Chicken| 60grams| Spoiled meat| Same colour as before/Light pink|
PORK BEEF CHICKEN
