Cheeseburger Experiment | Biology

Welcome to another post on my blog. In today's post, I am going to share the experiment that I've done in Biology today. I had to do the experiment myself.

Aim: To test if a sample of food contains complex sugar, simple sugar and protein.


Hypothesis: I think that it will have all of 

Bread
Meat
Cheese
Pickle

Will all change colour.


Equipment:

Complex Sugar:

1. Test Tube
2. Food Sample
3. Iodine Solution

Simple Sugar:

1. Water Bath
2. Test Tube Tongs
3. Benedict's Solution
4. A Sample of Food

Protein:

1. Test Tube
2. Sodium Hydroxide (NaOH)
3. Copper Sulfate (CuSO₄)
4. Food Sample

Method:

Complex Sugar:

1. Place about 2 ml of sample in a test tube.
2. Add 3-5 drops of iodine and mix.

Simple Sugar:

1. Place about 2ml of the sample into a test tube and then add 5 drops of Benedict's Solution.
2. Heat with a hot water bath until it changes colour. 

Protein:

1. Place about 2 ml of the sample into a test tube and add 5 drops of sodium hydroxide.
2. Add 5 drops of copper sulfate.
3. Shake the test tube gently from side to side.

Results:

Complex Sugar:
Bread has complex sugar. Meat doesn't have complex sugar. Cheese doesn't have complex sugar. Pickle has complex sugar.

Simple Sugar:
Bread is a simple sugar. Meat is not simple sugar. Cheese is not a simple sugar. Pickle is a simple sugar.


Protein:
Bread is not protein. I'll update the rest as soon as possible.

Conclusion:

In conclusion, my hypothesis didn't get all correct except some of them, like, meat, cheese and bread (in protein). What I had learnt in this experiment is that meat and cheese do not have complex or simple sugar.
