What do we have to do?
Find out why a piece of plain chapati tastes sweet after we chew it for some time.
What do we need?
A large piece of plain chapati.
How do we proceed?
Take a large piece of plain chapati. Chew it as much as you can.
What do we observe?
As the chapati changes into a fine paste, does it begin to taste sweet?
Answer (2)
As you chew chapati, the enzyme amylase in your saliva breaks down starches into sugars, producing a sweet taste. This process involves the mechanical breakdown of the chapati and chemical digestion beginning in the mouth. The sweet flavor signifies the presence of carbohydrates, which are important for energy.

When you chew a piece of plain chapati, you might notice that it begins to taste sweet after some time. This is an interesting biological phenomenon that involves the breakdown of starches by enzymes in your saliva.
What is Happening?
Role of Starch: Chapati is primarily made of flour, which contains a significant amount of starch. Starch is a complex carbohydrate made up of long chains of glucose molecules.
Saliva and Enzymes: When you chew the chapati, it mixes with your saliva. Saliva contains an enzyme called amylase.
Breaking Down Starch: Amylase starts breaking down the starch in the chapati into simpler sugars like maltose, which consist of glucose molecules.
Taste Change: Glucose and other simple sugars taste sweet, which is why, after chewing the chapati for a while, it starts to taste sweet.
Why Does This Happen?
This process is part of digestion, which begins in the mouth. Chewing helps to physically break down food, while enzymes in saliva start the chemical process of digestion. By breaking down the starch into simpler sugars, the body can more easily absorb and use them for energy.
Summary
In summary, the sweetness you taste is due to the enzymatic breakdown of starch in the chapati into sugars. This is an excellent example of how digestion begins in the mouth and the important role enzymes play in this process.
