Explanation:

Salivary amylase starts digestion of starch. Around 30% of total starch is digested by salivary amylase into maltose in the mouth. Pancreatic juice also has amylase enzyme which digests the remaining starch into disaccharides in the small intestine. Hence, digestion of starch starts in the mouth and continues in the small intestine.
