c) A method that determines whether a sensory difference exists between four products
d) A method that determines whether a sensory difference exists between five products
View Answer

Answer: a

a) Paired comparison testing
b) Triangle testing
c) Hedonic scaling
d) Du-trio testing
View Answer

Answer: a

4. Which of the following are difference tests?
a) Paired comparison testing
b) Ranking testing
c) Hedonic scaling
d) Du-trio testing
View Answer

Answer: d
Explanation: Du-trio testing and triangle testing are the two tests of difference tests. In a triangle test, the participants are told to taste a tray containing two identical, one different sample and to pick the odd sample out. Whereas in a duo-trio test, participants are told to match samples to a reference sample.

5. Which of the following are preference tests?
a) Paired comparison testing
b) Ranking testing
c) Hedonic scaling
d) Du-trio testing
View Answer

Answer: a
Explanation: Hedonic scaling and attribute rating scale are the two test of preference tests. In the hedonic scale method, the samples are presented singly and are rated on a scale. Attribute rating scale is defined as a closed-ended survey question.

6. What are the methods of sensory evaluation?
a) Discrimination, descriptive and affective
b) Discrimination and descriptive
c) Discrimination and affective
d) Descriptive and affective
View Answer

Answer: a

a) It records the intensity of perception
b) It is an easy method
c) It detects the difference between the samples
d) It requires skill labor
View Answer

Answer: a
Explanation: The scaling system is a more informative. It is therefore a useful form of recording the intensity of perception. The results are critically dependent on how well the panelists have been familiarized with the attribute.

b) False
View Answer

Answer: b
