1. Place 5 mL of starch solution in the test tubes. 2. Heat the test tubes to boiling and add to 1 mL of saliva, Cool and then continue heating but keep the test tube in a water bath at temperature of 40oC 3. At 5 minutes interval for 30 minutes take a drop of the reaction mixture from each test tube and test with Iodine solution (use a spot plate for the test and stir the contents of the test tube before taking a drop). Tabulate the results. 4. What would be the color of saliva extract with iodine in 3, 6, 9,12,15,and 18 minutes

The food we consume is broken down into simpler molecules that are used to yield energy for the body. The carbohydrate-based food items are digested into glucose which is further converted to energy. The breakdown of larger carbohydrates in the mouth is done by the enzyme salivary amylase which is present in the saliva.
