Saliva contains enzymes which catalyse the breakdown of starch to maltose and dextrin. If starch solution is treated with saliva, these simpler sugars will soon start to form, which means the mixture will give the Benedict's test.

What color develops when iodine solution is added to starch solution?

What is half saturation test of starch?
With 2ml of starch solution 2ml of saturated ammonium sulphate solution is added. Formation of gelatinous precipitate gives confirmation of presence of starch
What is the color of a solution when starch is added?
Benedicts tests for the presence of monosaccharides. It will turn a yellow to red color if it is a positive test, but it does not so starch does not contain monosaccharides. ...Actually..... If starch is heated at 250 degrees Celsius, it breaks down into sugar! a saccharide! The intense heat denatures the the starch and transforms it into sugar. Also, if you have starch and amylase ( enzyme found in your saliva) and heat that to 37 degrees Celsius, you will also get a sugar, but in the form of glucose!

What happens when benedict's solution is added to egg white and heated?
It causes the reaction to speed up showing more simple sugar in a solution, faster than just letting it sit.
