In which organ of the gastrointestinal tract does the breakdown of carbohydrates begin?

The breakdown of carbohydrates begins in the mouth. Saliva contains a digestive enzyme called amylase. It breaks down polysaccharides into monosaccharides. We can verify this ourselves. It is enough to put a small amount of starch into the oral cavity or just chew bread for a long time. We will feel a sweetish aftertaste. This is due to the breakdown of starch into glucose. Glucose tastes sweet. The breakdown of carbohydrates continues in other digestive organs. In the oral cavity, this process is just starting.
