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.
Salivary Amylase. Chewing breaks food into small molecules that combine with saliva secreted by the salivary glands in the mouth. Along with mucin and buffers, saliva contains the enzyme salivary amylase, which acts on the starch in food and breaks it down to maltose.his enzyme acts on the remaining polysaccharides and breaks them into disaccharide units of maltose. In the final step of complex carbohydrate digestion, the enzyme maltase present in the lining of the small intestine breaks maltose into two units of glucose.
