Our taste buds detect different flavors through tiny sensory organs called taste receptors. These receptors are sensitive to five basic tastes: sweet, sour, salty, bitter, and umami (savory). When food or drink enters the mouth, chemicals from the substance interact with saliva and come into contact with the taste receptors. This interaction sends signals to the brain, allowing us to perceive and identify different flavors.
