Starch is a substance common to most plant cells and so a weak iodine solution will stain starch present in the cells.

Using a petri dish gel, the saliva sample is added and allowed to diffuse through the gel overnight. Visualization is accomplished by adding iodine to the gel which stains the starch in the gel blue. If saliva is present, then the alpha-amylase breaks down the starch, creating a clear coloured circle around where the sample was placed.
