Explanation:

Iodine test for starch

Method:

Place one spatula of the food sample on a dish or 1 cm3 if the sample is liquid.

Using a dropper, place a few drops of iodine solution onto the food.

Record any change in the colour of the solution.

Starch is detected using iodine solution. This turns blue-black in the presence of starch.
