What is the process of making chewing gum
The digestive system allows us to take in food and break it down into basic nutrients that can be absorbed into the blood and used by the body. We previously learned that the mouth breaks food down mechanically with the process of chewing. We also learned that food is broken down chemically in the mouth with the presence of enzymes in the saliva called salivary amylase.

Professor Dey believes that through the process of chewing these vegetables, chemicals and enzymes are released that combine to form PEITC. She also believes that PEITIC plays a role in cancer prevention and control. However, it is not just a simple matter of eating some vegetables, but rather, eating lots of the right vegetables, consistently1. Dey’s studies have been designed to support her belief that sufficient cancer-preventing levels of PEITC can be achieved through diet alone.
Yet, the contribution of chewing to good digestion does not even stop there. The process of chewing also activates signaling messages to the rest of the gastrointestinal system that trigger it to begin the entire digestive process. This is because when chewing is a well-paced, thorough process, it can actually be said to belong to the "cephalic stage of digestion," the phase in which you first see, smell, and taste your food. The length of time spent chewing the food is related to the length of the cephalic stage of digestion since with more extensive chewing, the longer the food gets to be seen, tasted, and smelled. Cephalic phase responses have been extensively analyzed in the research literature. The release of small messaging molecules that are critical for digestion—such as cholecystokinin, somatostatin, and neurotensin—have been found to increase by over 50% just by the mere sight and smell of food. Additionally, research has shown how chewing, as well as the activation of taste receptors in the mouth, can prompt the nervous system to relay information to the gastrointestinal system to optimize the process of digestion. For example, stimulation of the taste receptors can signal the stomach lining to produce hydrochloric acid that helps in the breakdown of protein. Additionally, chewing signals the pancreas to prepare to secrete enzymes and bicarbonate into the lumen of the small intestines.The process of chewing causes under the tongue, and in the back of the mouth, to secrete saliva. The chewing then mixes the food with the . Saliva provides three benefits. It moistens and compacts the chewed food so the can roll it into a ball, called a bolus. It also lubricates the food, making it easier to swallow. Lastly, saliva contains digestive enzymes. Salivary amylase begins the breakdown of carbohydrates (e.g., starch). Salivary lipase begins the breakdown of fat. The salivary glands also secrete lysozyme that kills bacteria.
