Science Experiment - Protein - Complex Sugar & Simple Sugar.

Aim: 

To find out if there is Simple Sugars, Complex Sugars and Protein in a cheeseburger.

Equipment: 

Test Tube, Food Sample & Iodine Solution, Bunsen Burner, Test Tube Tongs, Benedicts Solution & A Sample Of Food, Sodium Hydroxide, Copper Sulfate.

Method:

Protein :

1. Place 2mL 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.

Simple Sugars : 

1. Place about 2mL of the sample into a test tube and then add 5 drops of Benedicts Solution.

2. Heat with a Bunsen until it changes color. Do not boil

Complex Sugars / Iodine :

1. Place about 2mL of the sample in the test tube.

2. Add 3-5 drops of iodine and mix. 

Results:

Conclusion:

Complex Sugar - Iodine:

Bun: The bun changed from white to black which determined there were complex sugars present.

Meat: The meat barely changed color and it there was no sugar present because it rarely changed color. 

Simple Sugar:

Unfortunately, no experiment was attempted for simple sugars.

Protein:

Bun: The bun remained the same color which indicated no sign of protein.

Meat Pattie: The meat pattie changed it's color to purple intimating signs of protein.
