Question 4

Difference between taste + flavour

• Flavour = perception/interpretation created by the brain

Question 5

Influences on flavour

Answer 5

• Perceptual set (expectations, past experience)
• Colour intensity
• Texture

Question 6

Perceptual set (expectations + past ecperience)

Answer 6

• Flavour interpretation can be manipulated if food is coloured/shaped/etc differently from how we expect
• E.g. we expect a red drink to taste like berry because of past experience

Question 7

Colour intensity

Answer 7

• We expect that foods with a richer/brighter colour will taste better
• Food producers manipulate our flavour perception by adding more colour to foods to make us think they taste better

Question 8

Texture

Answer 8

• The property of food/beverage that is felt in the mouth + contributes to flavour
• Often what we like/dislike about the texture of a food is a direct result of what we expect from that food
