PRACTICAL EXPERIENCE
TESTING FOODS FOR SUGARS

Materials:
Cube of cheese
Cube of potato
Cube of cookie
Cube of bread
Cube of ham
Iodine solution
Tissues or napkins

INTRUCTIONS :
Add iodine solution to a sample of the food.
Write in the results chart:

If there is starch present, a blue- black- violet colour is obtained. If there is not starch, the iodine solution remains orange – brown.

Write down your conclusion from the result of the test.


All my materials turn black with the iodine solution except the cheese, that means that it doesn’t store simple sugars, like starch. The vegetables store a lot of starch and that it’s why they turn black
