Learning objectives

• You will learn how your sense of smell in your nose and the sense of taste in your tongue work together when judging your food.

Would you dare to taste these snails?

No! Definitely not!

Imagine you are eating these chips..

How do you perceive the chips with your sense of..

- light

- touch

- hearing

- taste

- smell

Sense of smell

It is part of your nasal mucous membrane in the nasal cavity.

Aromatic substances= gasses that stimulate the sense of smell

Did you notice the mistake in this picture?

Why do we smell?

- Smell dangerous gasses

- Recognize spoiled food

- To taste better!

What do you think happens to the air when you sniff it?

1. Less air is present in your nasal cavity
2. The air flows more to the top of your nasal cavity
3. The air flows faster through your nasal cavity

Why do you smell better this way, than when you breathe in normally through the nose?

Sense of taste

Taste buds = bumps on the tongue between which the sensory cells are located

Flavours = stimulate the senses of taste

Flavours

• Sweet
  
• Salty
  
• Sour
• Bitter
  
• Umami
  

Umami = a savory taste that you know from meat, broth, soy sauce and tomatoes.

Taste = your brain combines information from your sense of smell and sense of taste.

When you have a cold and your nose is blocked, you taste less. How does that happen?

1. Your nasal cavity is not moist enough.
2. The fragrances do not reach the sense of smell.
3. Your tongue is too dry.
