mixed with saliva before swallowing starts. starch is decomposed by amylase and another
component of saliva is maltase, an enzyme catalyzing the catabolism of the disaccharide
maltose. assimilation also begins in the mouth. After food is thoroughly mixed with saliva
secretion then swallowing Process is initiated. involuntary peristaltic contractions transport the
food along the esophagus to the stomach.
