Starch is a complex polysaccharide which cannot be absorbed by the human digestive tract.
Hence, it is hydrolyzed into monosaccharide called maltose.
When the food is ingested, the glands present in mouth secrete a watery fluid called as saliva.
The saliva helps in the "proper mixing of food" in such a way that it is broken into pieces by chewing.
The enzyme present in the saliva hydrolyses the "starch present" in the food as maltose.
Hence, it can be inferred that starch is hydrolyzed in a maltose in mouth.
