Assessment 1
Sensory Analysis
Question #1
Which test helps to find out
whether Sample A or Sample B is
sweeter?
Paired Comparison
Test
Duo-trio Test
Correct!
•
In paired
comparison tests, panellists are asked to say
which of the two samples
is sweeter, spicier, etc.
•
It helps to confirm what a product developer might
predict about the effect of
modifying a food product.
For example, reducing the fat content of a biscuit
may make the end product mo
re crumbly.
Next Question
Think again!
HINTS:
•
There are only two samples: Sample A and Sample B.
•
In duo-trio test, panellists are asked to choose the
sample that matches the reference.
Go BACK and choose
the right answer
Question #2
A panel is asked to rate the taste
level of cream, malt and nut in a
chocolate sample.
This test is called Quantitative Descriptive Analysis.
True
False
Correct!
•
Descriptive tests are used to measure the type and
intensity of particular attributes of a food product
•
The test requires panellists to describe the product in
terms of its characteristics and to measure the
intensity of those characteristics and to measure the
intensity of those characteristics using scaling
methods
Next Question
Think again!
Go BACK and choose
the right answer
•
The answer should be TRUE
•
Descriptive tests are used to measure the type and
intensity of particular attributes of a food product
Questions #3
Which is an affective test?
Triangle test
Hedonic test
Duo-trio test
Think again!
Go BACK and choose
the right answer
HINTS:
•
In
triangle tests, the
panellists are asked to choose the
sample that is most different among three samples.
•
It does not involve affection.
Think again!
Go BACK and choose
the right answer
HINTS:
•
In
duo-trio tests, panellists
are asked to choose the
sample that matches the reference.
•
It does not involve affection.
Correct!
•
Hedonic test is used to measure how much people
like a product
.
•
It is an affective test.
The End
Explore different sensory analysis tests used in food evaluation, including paired comparison tests for sweetness, quantitative descriptive analysis for taste attributes, and affective tests like hedonic tests. Understand the purpose and methodology of each test to enhance product development and quality control in the food industry.
