You can use starch-iodine in place of DCPIP to test vitamin C. Mechanism: The ascorbic acid reduces the iodine to iodide so it no longer forms the starch-iodine complex. Procedure: 1ml of starch is placed in a suitable receptacle and 1 drop of iodine solution added. The ascorbic acid solution is then added drop wise until the blue-black colour of the starch iodine complex disappear to leave a colourless solution.
