Taste
How Do We Sense the Taste of Food?
Foods have different flavors. However, if the food is extremely hot or cold, we are often unable to taste it properly.
On the tongue and inside the mouth, there are groups of taste receptors called taste buds. After food dissolves in saliva, the dissolved substances bind to these receptors and trigger nerve signals. These signals are sent to the brain, where the taste is identified and interpreted.

Quick Fact
Taste buds can detect five basic flavors: sweet, salty, sour, bitter, and umami. The full experience of flavor also involves smell and texture.
Important Concept
Taste buds detect dissolved substances in food. These substances trigger nerve signals that are sent to the brain, allowing us to recognize different flavors.
Common Mistake
Some people think we taste food only with the tongue. In fact, the sense of taste also depends on smell, temperature, and texture to create a complete flavor experience.
Questions
Show Answer
The food must dissolve in saliva so that the dissolved substances can bind to taste receptors and trigger nerve signals.
Show Answer
Extreme temperatures can reduce the effectiveness of taste receptors or mask flavor signals, making it harder to detect taste accurately.
