Chewed food mixed with saliva is called a Bolus, which is swallowed once mastication is complete. Bolus is the food that has been chewed and mixed in the mouth with saliva. Chewing helps to reduce food particles to a size readily swallowed; saliva adds digestive enzymes, water, and mucus that help chemically to reduce food particles, hydrate them for taste, and lubricate them for swallowing.
