Testing Sugars

Aim: 

To test if a sample of food contains complex sugars

Equipment: 

Test tube
Food sample
Iodine solution

Method:

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

Results: 

The bread in the test tube went from a reddish brown like colour to a dark brown or black colour. This means there are complex carbs
