to increase the surface area on which enzymes can act upon

The answers about surface area are only partly right. Chewing allows amylase from the saliva to get to, and to better act on the starches within the food. It then forms into a bolus, or lump, of food during swallowing. This bolus sits in your stomach, but, being a bolus, the amylase is protected, and has more time to act on the starch, before being deactivated by the acids in your stomach.
If you did not chew your food well, or eat starchy food like hamburgers, pasta etc without chewing it properly, then the starch is not broken down properly into sugars, and is more likely to become fat deposition.

Chewing breaks down the food into smaller particles. This maximizes the surface area on which enzymes can have contact with the food, facilitating hydrolysis.

chewing gives the enzymes a larger surface to work on so sppeds up the reaction. it also helps the enzymes to get to all the food
