If using acid-catalyzed hydrolysis of starch you can tell the hydrolysis is complete with the solution no longer gives a bluish/purple color with iodine solution. The color should be colorless.
As you hydrolyze starch, you make glucose molecules.

it is positive for starch hydrolysis
Amylose is made up of α(1→4) bonded glucose monomers, so glucose is the only product of complete hydrolytic breakdown. It is unclear which test is used, please rephrase the question in an appropriate way (one at a time, not THREE! like this).
One way to detect starch hydrolysis is to observe a zone of clearing around the bacterial growth on starch agar plates. This clearing indicates that the bacteria produced amylase, which broke down the starch in the agar. Additionally, testing for the presence of reducing sugars, such as glucose or maltose, could also indicate starch hydrolysis.
The hydrolysis of starch occurs in the reaction mixture containing the enzyme amylase, which breaks down starch into smaller sugars such as maltose and glucose. This process of breaking down starch into simpler sugars is known as enzymatic hydrolysis.

The end products of the complete hydrolysis of starch are glucose molecules. Starch is a polysaccharide made up of many glucose units, so when it is fully broken down through hydrolysis, it yields individual glucose molecules.
Starch has a dextrose equivalent of zero because that is the definition of DE 0. a scale was needed for measuring the hydrolysis of starch starting at pure starch to complete 100% dextrose. It was decided to assign zero to pure starch and 100 to 100% dextrose.
ptyalin
The disaccharide products of the hydrolysis of starch are maltose and isomaltose. These disaccharides are composed of two glucose molecules linked together.
You could use iodine in a starch hydrolysis test to detect the presence of starch. Without iodine, alternative methods such as using enzymatic assays to directly measure the breakdown products of starch hydrolysis could be employed. Additionally, techniques like TLC or HPLC could be used to analyze the carbohydrate composition before and after the hydrolysis process.
