How to test for starch with iodine
How To Test For Starch With Iodine. During the mash the enzymes should convert all the available starch to sugar. The brown iodine solution reacts with starch and changes it to a blue black color. Starch amylopectin does not give the color nor does cellulose nor do disaccharides such as sucrose in sugar. The tube on the left contains only water and the test prod.

A blue black color results if starch is present. This test is commonly called the iodine test. Starch glycogen and higher dextrins on reaction with dilute iodine solution form coloured compounds. This test helps you to find out if a food contains starch. The iodine test is used to test for the presence of starch starch turns into an intense blue black colour upon addition of aqueous solutions of the triiodide anion due to the formation of an intermolecular charge transfer complex. If starch amylose is not present then the color will stay orange or yellow.
The test can be subjective or quantitative.
