Sensory Evaluation Or…what is that SMELL?

Sensory Evaluation Scientific testing of food using: – Sight – Smell – Taste – Touch – and Hearing

Use your eyes Can you identify each of these foods by sight? Do you like to eat them? Why?

Close your eyes Can you smell coffee? Can you smell popcorn? Can you smell pizza? Can you smell bacon?

So how is it that you can smell things with out them actually being there? Your mind’s memory has recorded each of those for you. Your experiences smelling these food items over time has put an imprint in your brain. The food does not even need to be present.

How does it work? Odor molecules enter nostrils Get caught in the receptor nerve cells Cilia produce impulses that are sent to the olfactory nerve

In the brain the signal is interpreted by the olfactory bulb and you notice an odor. Your eyesight gives that odor a picture in your brain.

Together they create a memory which is stored in the hippocampus.

So the next time you smell a rose…

You’ll know exactly what it is
