Salivary glands located under the tongue, and in the back of the mouth, produce saliva in the mouth. Enzymes in the saliva start the chemical digestion of food. Amylase starts the breakdown of carbohydrates, while salivary lipase begins the breakdown of fats.Once the food arrives at the stomach, gastric glands secrete pepsinogen and hydrochloric acid. Pepsinogen helps with the digestion of protein.nzymes in the saliva start the chemical digestion of food. Amylase starts the breakdown of carbohydrates, while salivary lipase begins the breakdown of fats.
