Answer to Question 2
The process of digestion begins in the mouth. Fluids help dissolved the food so that the tongue can taste it; only particles in solution can react with taste buds. When stimulated, the taste buds detect one, or a combination, of the five basic taste sensations: sweet, sour, bitter, salty, and umami. In addition to these chemical triggers, aroma, appearance, texture, and temperature also affect a food's flavor.
