Detailed Solution

The given statement is false.

Carbohydrates are present in our food in the form of starch and sugars. Food items having starch can be confirmed by a simple iodine test.

Take the food item in a test tube and add 2-3 drops of dilute iodine solution into it. To mix the contents gently shake the test tube. If the colour of the food in the test tube changes to blue-black, it means that the food contains starch in it.

Copper sulphate solution is used for testing proteins in food.

Thus, the correct statement is, "Iodine solution is used to test for starch in food."
