  1. Prepare 2 samples of food product you wish to test. 2. Compare 1 attribute, e.g which one is smoother? 3. Record responses from tasters.
55
Q

Duo Trio Test (Discrimination)

A

56
Q

Ranking (Preference)

A

57
Q

58
Q

Star Diagram/Chart Uses

A

They can be used to: evaluate differences in similar products, gauge consumer response, analyse specific attributes e.g shortness, check that food product meets its original specification, compare similarities in range of products + show new opportunities for product development.

59
Q

How to Model Sensory Attributes

A
  1. Choose range of attributes that describe characteristics of product e.g crunchy, spicy or smooth. 2. Decide on intensity of each attribute, using scale from 0-10 (higher number = higher intensity). 3. Use information to produce star diagram/chart of product’s attributes.
60
Q

Number of Adult Taste Buds

A

62
Q

Where are taste buds mainly found?

A

Most taste buds are on tongue.

63
Q

How Taste Works

A

Chemical substance for taste of food comes into contact with nerve cell in mouth, sensory cell transmits messenger substances, which activate further nerve cells, these nerve cells pass on information for particular flavour perception to brain, taste papillae on tongue contain many sensory cells + together with other cells they make up taste bud that looks bit like orange with its sections arranged around centre + chemical substances responsible for taste are washed on to taste papillae + then are detected + analysed by many taste buds before being swallowed.
