What is a Food Bolus? A food bolus is a small, round mass of food that is formed in the mouth during the early phase of digestion. A food bolus is formed when a piece of food is chewed, lubricated with saliva, mixed with enzymes and formed into a soft, lubricated and cohesive mass. The bolus is held in the mouth, or oral cavity, until the process of swallowing begins.
Ingestion, digestion then absorption. In the mouth, both chemical digestion and mechanical digestion happen. The mechanical part is your teeth crushing the food into smaller pieces. The chemical part is when the salivary glands give off a special fluid that contains enzymes.igestion of carbohydrates start in the mouth. Amylase, an enzyme in saliva, hydrolyzes starch and glycogen into smaller polysaccharides. This digestion continues in the stomach after the food (bolus) passes through the esophagus.
