How do things taste without your sense of smell?

Taste Testing Without Smell

We all know that some foods taste better

 than others but what gives us the ability

 to experience all these unique flavours? This simple

 experiment shows that there's a lot more to taste

 than you might have first thought




What you'll need:

  • A small piece of peeled potato
  • A small piece of peeled apple (same shape as the potato so you                                                    can't tell the difference)

 

Instructions:

  1. Close your eyes and mix up the piece of potato and the piece                                                    of apple so you don't know which is which.
  2. Hold your nose and eat each piece, can you tell the difference?

 

What's happening?

Holding your nose while tasting the potato and apple makes

 it hard to tell the difference between the two. Your nose and

mouth are connected through the same airway which means

 that you taste and smell foods at the same time. Your sense

 of taste can recognize salty, sweet, bitter and sour but when

 you combine this with your sense of smell you can recognize

many other individual 'tastes'. Take away your smell (and sight)

 and you limityour brains ability to tell the difference between

 certain foods.
