The section of the digestive system in which starch begins to break down.

Starch is broken down at the very beginning of the entry of food into the oral cavity. During the chewing of food, the enzyme amylase appears. It is produced by the salivary glands. As a result of the abundant wetting of food and the chemical process, starch is converted into glucose. This process can be experienced while chewing with the help of taste. Initially unsweetened foods become sweetish. For example, (bread, potatoes).
