Chewing, or mastication, uses the teeth to mechanically tear apart the food. Saliva contains amylase, an enzyme that breaks down starches in the mouth.
The starch breaks down and becomes small hexagonal glucose molecules.
Starch is sugar. Starch is the name they give to a polymer of glucose.

When boiled rice is chewed, the salivary amylase of the saliva changes the starch to maltose. Thus it tasted sweet and gave a negative result with iodine.Thanks
Bread is carbohydrate, specifically starch. As we masticate, amylase is produced by the saliva which converts starch to maltose which is a sugar. Hence bread tastes sweet on mastication.Bread tastes sweet on mastication (chewing) because the enzymes in saliva begin converting the starch in bread to sugar.

Carbohydrate Metabolism begins in the mouth. If you chew a piece of plain bread for a while, you'll find that it begins to taste sweet. That's because the starch is being metabolised into a sweet substance by the enzymes in the mouth. Hope this helps :)
The process of digestion begins in the mouth. As you chew foods, you release saliva into your mouth. Your saliva begins to convert starches into sugars before the food even gets to your stomach, so the starch in the chips begins to taste sweeter as you chew it. The flavor turns sweeter the longer you chew to mix in your saliva and cause the conversion to begin.
The starch turns into sugar.

Saliva is the first thing that breaks down the starch. In fact, the most important part of starch digestion occurs in the mouth, so chew your complex carbohydrates (starch), very well!
