Dear student,
Saliva contains the enzyme amylase, also called ptyalin, which is capable of breaking down starch into simpler sugars such as maltose and dextrin that can be further broken down in the small intestine. Only about 30% starch digestion takes place in the mouth cavity.
it also softens the food.As a primary enzyme in saliva, amylase starts to break down starches in the food you eat. Starches are long chains of sugars attached to each other, and amylase breaks the bonds along the chain to release maltose sugar molecules.
Thank you.
