The answer would probably be starch since this is the only nutrient that start to be digested in mouth and along the esophagus to the stomach.
More accurate to say 'none', for although saliva does start digestion that is added in the mouth and the oesophagus is simply the conduit from mouth to stomach.
It is starch! I think
Starch is digested by ptyalin.
food!!
Protein into amino acids by enzymes and hydrochloric acid!
Peristalsis primarily occurs in the esophagus and the intestines. In the esophagus, it facilitates the movement of food from the throat to the stomach. In the intestines, peristalsis helps propel digested food through the digestive tract, aiding in nutrient absorption and waste elimination.
Amino Acid
Sesame seeds are a very good source of fibre and roughage which cleans out your digestive system. They are also 25% protein, including methionine and tryptophan, which may be missing from other plant foods.
The esophagus leads to the frog's stomach. The esophagus is a tube that connects the mouth to the stomach, allowing food to pass and be digested.
The pharynx is the tube which food passes threw after it is chemically and mechanically digested in the mouth. This leads to the esophagus then to the stomach.

It's because in the mouth we masticate the food.Mastication increases the surface area of the food which helps to accelerate the breakdown of the carbohydrate molecules.Whereas in other parts of the digestive system where foods are chemically digested mastication does not occur.so foods containing starch start to be chemically digested.
The esophagus works with other systems of the body by transporting food down to the stomach so it can be digested.
